GUIDELINES FOR GETTING
STARTED WITH 32-BIT MCUS
Note 1: This data sheet summarizes the features
of the PIC32MX330/350/370/430/450/
470 family of devices. It is not intended to
be a comprehensive reference source.
To complement the information in this
data sheet, refer to the related section of
the “PIC32 Family Reference Manual”,
which is available from the Microchip
web site (www.microchip.com/PIC32).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
2.1
Basic Connection Requirements
Getting started with the PIC32MX330/350/370/430/
450/470 family of 32-bit Microcontrollers (MCUs)
requires attention to a minimal set of device pin connections before proceeding with development. The following is a list of pin names, which must always be
connected:
• All VDD and VSS pins (see 2.2 “Decoupling Capacitors”)
• All AVDD and AVSS pins, even if the ADC module is
not used (see 2.2 “Decoupling Capacitors”)
• VCAP pin (see 2.3 “Capacitor on Internal Voltage
Regulator (VCAP)”)
• MCLR pin (see 2.4 “Master Clear (MCLR) Pin”)
• PGECx/PGEDx pins, used for In-Circuit Serial Programming (ICSP™) and debugging purposes (see
2.5 “ICSP Pins”)
• OSC1 and OSC2 pins, when external oscillator
source is used (see 2.8 “External Oscillator Pins”)
The following pin may be required, as well:
2.2
Decoupling Capacitors
The use of decoupling capacitors on power supply
pins, such as VDD, VSS, AVDD and AVSS is required.
See Figure 2-1.
Consider the following criteria when using decoupling
capacitors:
• Value and type of capacitor: A value of 0.1 µF
(100 nF), 10-20V is recommended. The capacitor
should be a low Equivalent Series Resistance (lowESR) capacitor and have resonance frequency in
the range of 20 MHz and higher. It is further
recommended that ceramic capacitors be used.
• Placement on the printed circuit board: The
decoupling capacitors should be placed as close to
the pins as possible. It is recommended that the
capacitors be placed on the same side of the board
as the device. If space is constricted, the capacitor
can be placed on another layer on the PCB using a
via; however, ensure that the trace length from the
pin to the capacitor is within one-quarter inch
(6 mm) in length.
• Handling high frequency noise: If the board is
experiencing high frequency noise, upward of tens
of MHz, add a second ceramic-type capacitor in parallel to the above described decoupling capacitor.
The value of the second capacitor can be in the
range of 0.01 µF to 0.001 µF. Place this second
capacitor next to the primary decoupling capacitor.
In high-speed circuit designs, consider implementing a decade pair of capacitances as close to the
power and ground pins as possible. For example,
0.1 µF in parallel with 0.001 µF.
• Maximizing performance: On the board layout
from the power supply circuit, run the power and
return traces to the decoupling capacitors first, and
then to the device pins. This ensures that the decoupling capacitors are first in the power chain. Equally
important is to keep the trace length between the
capacitor and the power pins to a minimum thereby
reducing PCB track inductance.
VREF+/VREF- pins, used when external voltage
reference for the ADC module is implemented.
Note:
The AVDD and AVSS pins must be
connected, regardless of ADC use and
the ADC voltage reference source.

ICSP Pins
2.7
Trace
The PGECx and PGEDx pins are used for In-Circuit
Serial Programming™ (ICSP™) and debugging purposes. It is recommended to keep the trace length
between the ICSP connector and the ICSP pins on the
device as short as possible. If the ICSP connector is
expected to experience an ESD event, a series resistor
is recommended, with the value in the range of a few
tens of Ohms, not to exceed 100 Ohms.
The trace pins can be connected to a hardware
trace-enabled programmer to provide a compressed
real-time instruction trace. When used for trace, the
TRD3, TRD2, TRD1, TRD0 and TRCLK pins should
be dedicated for this use. The trace hardware
requires a 22 Ohm series resistor between the trace
pins and the trace connector.
Pull-up resistors, series diodes and capacitors on the
PGECx and PGEDx pins are not recommended as they
will interfere with the programmer/debugger communications to the device. If such discrete components are
an application requirement, they should be removed
from the circuit during programming and debugging.
Alternatively, refer to the AC/DC characteristics and
timing requirements information in the respective
device Flash programming specification for information
on capacitive loading limits and pin input voltage high
(VIH) and input low (VIL) requirements.
2.8
Ensure that the “Communication Channel Select” (i.e.,
PGECx/PGEDx pins) programmed into the device
matches the physical connections for the ICSP to
MPLAB® ICD 3 or MPLAB REAL ICE™.
For more information on ICD 3 and REAL ICE
connection requirements, refer to the following
documents that are available on the Microchip web

External Oscillator Pins
Many MCUs have options for at least two oscillators: a
high-frequency primary oscillator and a low-frequency
secondary oscillator (refer to Section 8.0 “Oscillator
Configuration” for details).
The oscillator circuit should be placed on the same side
of the board as the device. Also, place the oscillator circuit close to the respective oscillator pins, not exceeding one-half inch (12 mm) distance between them. The
load capacitors should be placed next to the oscillator
itself, on the same side of the board. Use a grounded
copper pour around the oscillator circuit to isolate them
from surrounding circuits. The grounded copper pour
should be routed directly to the MCU ground. Do not
run any signal traces or power traces inside the ground
pour. Also, if using a two-sided board, avoid any traces
on the other side of the board where the crystal is
placed. A suggested layout is illustrated in Figure 2-3.

The TMS, TDO, TDI and TCK pins are used for testing
and debugging according to the Joint Test Action
Group (JTAG) standard. It is recommended to keep the
trace length between the JTAG connector and the
JTAG pins on the device as short as possible. If the
JTAG connector is expected to experience an ESD
event, a series resistor is recommended, with the value
in the range of a few tens of Ohms, not to exceed 100
Ohms.
Pull-up resistors, series diodes and capacitors on the

as they will interfere with the programmer/debugger
communications to the device. If such discrete components are an application requirement, they should be

3.2.1
EXECUTION UNIT
The MIPS32® M4K® processor core execution unit
implements a load/store architecture with single-cycle
ALU operations (logical, shift, add, subtract) and an
autonomous multiply/divide unit. The core contains
thirty-two 32-bit General Purpose Registers (GPRs)
used for integer operations and address calculation.
One additional register file shadow set (containing
thirty-two registers) is added to minimize context
switching overhead during interrupt/exception processing. The register file consists of two read ports and one
write port and is fully bypassed to minimize operation
latency in the pipeline.
The execution unit includes:
• 32-bit adder used for calculating the data address
• Address unit for calculating the next instruction
address
• Logic for branch determination and branch target
address calculation
• Load aligner
• Bypass multiplexers used to avoid stalls when
executing instruction streams where data
producing instructions are followed closely by
consumers of their results
• Leading Zero/One detect unit for implementing
the CLZ and CLO instructions
• Arithmetic Logic Unit (ALU) for performing bitwise
logical operations
• Shifter and store aligner
TABLE 3-1:
MULTIPLY/DIVIDE UNIT (MDU)
The MIPS32® M4K® processor core includes a Multiply/Divide Unit (MDU) that contains a separate pipeline
for multiply and divide operations. This pipeline operates in parallel with the Integer Unit (IU) pipeline and
does not stall when the IU pipeline stalls. This allows
MDU operations to be partially masked by system stalls
and/or other integer unit instructions.
The high-performance MDU consists of a 32x16 booth
recoded multiplier, result/accumulation registers (HI
and LO), a divide state machine, and the necessary
multiplexers and control logic. The first number shown
(‘32’ of 32x16) represents the rs operand. The second
number (‘16’ of 32x16) represents the rt operand. The
PIC32 core only checks the value of the latter (rt) operand to determine how many times the operation must
pass through the multiplier. The 16x16 and 32x16
operations pass through the multiplier once. A 32x32
operation passes through the multiplier twice.
The MDU supports execution of one 16x16 or 32x16
multiply operation every clock cycle; 32x32 multiply
operations can be issued every other clock cycle.
Appropriate interlocks are implemented to stall the
issuance of back-to-back 32x32 multiply operations.
The multiply operand size is automatically determined
by logic built into the MDU.
Divide operations are implemented with a simple 1 bit
per clock iterative algorithm. An early-in detection
checks the sign extension of the dividend (rs) operand.
If rs is 8 bits wide, 23 iterations are skipped. For a 16-bit
wide rs, 15 iterations are skipped and for a 24-bit wide
rs, 7 iterations are skipped. Any attempt to issue a subsequent MDU instruction while a divide is still active
causes an IU pipeline stall until the divide operation is
completed.
Table 3-1 lists the repeat rate (peak issue rate of cycles
until the operation can be reissued) and latency (number of cycles until a result is available) for the PIC32
core multiply and divide instructions. The approximate
latency and repeat rates are listed in terms of pipeline
clocks.

PIC32MX330/350/370/430/450/470
The MIPS architecture defines that the result of a
multiply or divide operation be placed in the HI and LO
registers. Using the Move-From-HI (MFHI) and MoveFrom-LO (MFLO) instructions, these values can be
transferred to the General Purpose Register file.
In addition to the HI/LO targeted operations, the
MIPS32® architecture also defines a multiply instruction,
MUL, which places the least significant results in the primary register file instead of the HI/LO register pair. By
avoiding the explicit MFLO instruction required when
using the LO register, and by supporting multiple destination registers, the throughput of multiply-intensive
operations is increased.
3.2.3
SYSTEM CONTROL 
COPROCESSOR (CP0)
In the MIPS architecture, CP0 is responsible for the
virtual-to-physical address translation, the exception
control system, the processor’s diagnostics capability,
the operating modes (Kernel, User and Debug) and
whether interrupts are enabled or disabled. Configuration information, such as presence of options like
MIPS16e®, is also available by accessing the CP0
registers, listed in Table 3-2.
Two other instructions, Multiply-Add (MADD) and
Multiply-Subtract (MSUB), are used to perform the
multiply-accumulate and multiply-subtract operations.
The MADD instruction multiplies two numbers and then
adds the product to the current contents of the HI and
LO registers. Similarly, the MSUB instruction multiplies
two operands and then subtracts the product from the
HI and LO registers. The MADD and MSUB operations
are commonly used in DSP algorithms.

Power Management
3.4
MIPS®
The
M4K® processor core offers a number of
power management features, including low-power
design, active power management and power-down
modes of operation. The core is a static design that
supports slowing or Halting the clocks, which reduces
system power consumption during Idle periods.
3.3.1
INSTRUCTION-CONTROLLED
POWER MANAGEMENT
The mechanism for invoking Power-Down mode is
through execution of the WAIT instruction. For more
information on power management, see Section 26.0
“Power-Saving Features”.
3.3.2
LOCAL CLOCK GATING
The majority of the power consumed by the
PIC32MX330/350/370/430/450/470 family core is in
the clock tree and clocking registers. The PIC32MX
family uses extensive use of local gated-clocks to
reduce this dynamic power consumption.
DS60001185B-page 36
EJTAG Debug Support
The MIPS® M4K® processor core provides for an
Enhanced JTAG (EJTAG) interface for use in the software debug of application and kernel code. In addition
to standard User mode and Kernel modes of operation,
the M4K® core provides a Debug mode that is entered
after a debug exception (derived from a hardware
breakpoint, single-step exception, etc.) is taken and
continues until a Debug Exception Return (DERET)
instruction is executed. During this time, the processor
executes the debug exception handler routine.
The EJTAG interface operates through the Test Access
Port (TAP), a serial communication port used for transferring test data in and out of the core. In addition to the
standard JTAG instructions, special instructions
defined in the EJTAG specification define which
registers are selected and how they are used.

“Memory Organization” (DS60001115)
in the “PIC32 Family Reference Manual”,
which is available from the Microchip
web site (www.microchip.com/PIC32).
PIC32MX330/350/370/430/450/470 microcontrollers
provide 4 GB of unified virtual memory address space.
All memory regions, including program, data memory,
SFRs and Configuration registers, reside in this
address space at their respective unique addresses.
The program and data memories can be optionally partitioned into user and kernel memories. In addition, the
data memory can be made executable, allowing
PIC32MX330/350/370/430/450/470 devices to execute
from data memory.
Memory Layout
PIC32MX330/350/370/430/450/470 microcontrollers
implement two address schemes: virtual and physical.
All hardware resources, such as program memory,
data memory and peripherals, are located at their
respective physical addresses. Virtual addresses are
exclusively used by the CPU to fetch and execute
instructions as well as access peripherals. Physical
addresses are used by bus master peripherals, such as
DMA and the Flash controller, that access memory
independently of the CPU.
The memory maps for the PIC32MX330/350/370/430/
450/470 devices are illustrated in Figure 4-1 through
Figure 4-3.
Key features include:
• 32-bit native data width
• Separate User (KUSEG) and Kernel (KSEG0/
KSEG1) mode address space
• Flexible program Flash memory partitioning
• Flexible data RAM partitioning for data and
program space
• Separate boot Flash memory for protected code
• Robust bus exception handling to intercept 
runaway code
• Simple memory mapping with Fixed Mapping
Translation (FMT) unit

FLASH PROGRAM MEMORY
Note 1: This data sheet summarizes the features
of the PIC32MX330/350/370/430/450/
470 family of devices. It is not intended to
be a comprehensive reference source.
To complement the information in this
data sheet, refer to Section 5. “Flash
Program Memory” (DS60001121) in the
“PIC32 Family Reference Manual”, which
is available from the Microchip web site
(www.microchip.com/PIC32).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
PIC32MX330/350/370/430/450/470 devices contain an
internal Flash program memory for executing user
code. There are three methods by which the user can
program this memory:
• Run-Time Self-Programming (RTSP)
• EJTAG Programming
• In-Circuit Serial Programming™ (ICSP™)
RTSP is performed by software executing from either
Flash or RAM memory. Information about RTSP
techniques is available in Section 5. “Flash Program
Memory” (DS60001121) in the “PIC32 Family
Reference Manual”.
EJTAG is performed using the EJTAG port of the
device and an EJTAG capable programmer.
ICSP is performed using a serial data connection to the
device and allows much faster programming times than
RTSP.
The EJTAG and ICSP methods are described in the
“PIC32
Flash
Programming
Specification”
(DS60001145), which can be downloaded from the
Microchip web site.

DIRECT MEMORY ACCESS
(DMA) CONTROLLER
Note 1: This data sheet summarizes the features
of the PIC32MX330/350/370/430/450/
470 family of devices. It is not intended to
be a comprehensive reference source.
To complement the information in this
data sheet, refer to Section 31. “Direct
Memory Access (DMA) Controller”
(DS60001117) in the “PIC32 Family
Reference Manual”, which is available
from
the
Microchip
web
site
(www.microchip.com/PIC32).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
The PIC32 Direct Memory Access (DMA) controller is a
bus master module useful for data transfers between
different devices without CPU intervention. The source
and destination of a DMA transfer can be any of the
memory mapped modules existent in the PIC32 (such
as Peripheral Bus (PBUS) devices: SPI, UART, PMP,
etc.) or memory itself.
Following are some of the key features of the DMA
controller module:
• Four identical channels, each featuring:
- Auto-increment source and destination
address registers
- Source and destination pointers
- Memory to memory and memory to
peripheral transfers
FIGURE 10-1:
INT Controller
Peripheral Bus
• Automatic word-size detection:
- Transfer granularity, down to byte level
- Bytes need not be word-aligned at source
and destination
• Fixed priority channel arbitration
• Flexible DMA channel operating modes:
- Manual (software) or automatic (interrupt)
DMA requests
- One-Shot or Auto-Repeat Block Transfer
modes
- Channel-to-channel chaining
• Flexible DMA requests:
- A DMA request can be selected from any of
the peripheral interrupt sources
- Each channel can select any (appropriate)
observable interrupt as its DMA request
source
- A DMA transfer abort can be selected from
any of the peripheral interrupt sources
- Pattern (data) match transfer termination
• Multiple DMA channel status interrupts:
- DMA channel block transfer complete
- Source empty or half empty
- Destination full or half full
- DMA transfer aborted due to an external
event
- Invalid DMA address generated
• DMA debug support features:
- Most recent address accessed by a DMA
channel
- Most recent DMA channel to transfer data
• CRC Generation module:
- CRC module can be assigned to any of the
available channels
- CRC module is highly configurable

Writing to this register will seed the CRC generator. Reading from this register will return the current value of
the CRC. Bits greater than PLEN will return ‘0’ on any read.
When CRCTYP (DCRCCON<15>) = 1 (CRC module is in IP Header mode):
Only the lower 16 bits contain IP header checksum information. The upper 16 bits are always ‘0’. Data written
to this register is converted and read back in 1’s complement form (i.e., current IP header checksum value).
When CRCTYP (DCRCCON<15>) = 0 (CRC module is in LFSR mode):
Bits greater than PLEN will return ‘0’ on any read.

The chain selection bit takes effect when chaining is enabled (i.e., CHCHN = 1).
When the channel is suspended by clearing this bit, the user application should poll the CHBUSY bit (if
available on the device variant) to see when the channel is suspended, as it may take some clock cycles
to complete a current transaction before the channel is suspended.

USB ON-THE-GO (OTG)
Note 1: This data sheet summarizes the features
of the PIC32MX330/350/370/430/450/
470 family of devices. It is not intended to
be a comprehensive reference source.
To complement the information in this
data sheet, refer to Section 27. “USB
On-The-Go (OTG)” (DS60001126) in the
“PIC32 Family Reference Manual”, which
is available from the Microchip web site
(www.microchip.com/PIC32).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
The Universal Serial Bus (USB) module contains
analog and digital components to provide a USB 2.0
full-speed and low-speed embedded host, full-speed
device or OTG implementation with a minimum of
external components. This module in Host mode is
intended for use as an embedded host and therefore
does not implement a UHCI or OHCI controller.
The USB module consists of the clock generator, the
USB voltage comparators, the transceiver, the Serial
Interface Engine (SIE), a dedicated USB DMA controller, pull-up and pull-down resistors, and the register
interface. A block diagram of the PIC32 USB OTG
module is presented in Figure 11-1.
 2012-2013 Microchip Technology Inc.
The clock generator provides the 48 MHz clock
required for USB full-speed and low-speed communication. The voltage comparators monitor the voltage on
the VBUS pin to determine the state of the bus. The
transceiver provides the analog translation between
the USB bus and the digital logic. The SIE is a state
machine that transfers data to and from the endpoint
buffers and generates the hardware protocol for data
transfers. The USB DMA controller transfers data
between the data buffers in RAM and the SIE. The integrated pull-up and pull-down resistors eliminate the
need for external signaling components. The register
interface allows the CPU to configure and
communicate with the module.
The PIC32 USB module includes the following
features:
•
•
•
•
•
•
•
•
•
USB Full-speed support for host and device
Low-speed host support
USB OTG support
Integrated signaling resistors
Integrated analog comparators for VBUS
monitoring
Integrated USB transceiver
Transaction handshaking performed by hardware
Endpoint buffering anywhere in system RAM
Integrated DMA to access system RAM and Flash

12.0
General purpose I/O pins are the simplest of peripherals. They allow the PIC® MCU to monitor and control
other devices. To add flexibility and functionality, some
pins are multiplexed with alternate function(s). These
functions depend on which peripheral features are on
the device. In general, when a peripheral is functioning,
that pin may not be used as a general purpose I/O pin.
I/O PORTS
Note 1: This data sheet summarizes the features
of the PIC32MX330/350/370/430/450/

12.1
12.1.3
Parallel I/O (PIO) Ports
All port pins have ten registers directly associated with
their operation as digital I/O. The data direction register
(TRISx) determines whether the pin is an input or an
output. If the data direction bit is a ‘1’, then the pin is an
input. All port pins are defined as inputs after a Reset.
Reads from the latch (LATx) read the latch. Writes to
the latch write the latch. Reads from the port (PORTx)
read the port pins, while writes to the port pins write the
latch.
12.1.1
OPEN-DRAIN CONFIGURATION
In addition to the PORTx, LATx, and TRISx registers for
data control, some port pins can also be individually
configured for either digital or open-drain output. This is
controlled by the Open-Drain Control register, ODCx,
associated with each port. Setting any of the bits configures the corresponding pin to act as an open-drain
output.
The open-drain feature allows the generation of outputs higher than VDD (e.g., 5V) on any desired 5V-tolerant pins by using external pull-up resistors. The
maximum open-drain voltage allowed is the same as
the maximum VIH specification.
See the “Pin Diagrams” section for the available pins
and their functionality.
12.1.2
CONFIGURING ANALOG AND
DIGITAL PORT PINS
The ANSELx register controls the operation of the
analog port pins. The port pins that are to function as
analog inputs must have their corresponding ANSEL
and TRIS bits set. In order to use port pins for I/O
functionality with digital modules, such as Timers,
UARTs, etc., the corresponding ANSELx bit must be
cleared.
The ANSELx register has a default value of 0xFFFF;
therefore, all pins that share analog functions are
analog (not digital) by default.
If the TRIS bit is cleared (output) while the ANSELx bit
is set, the digital output level (VOH or VOL) is converted
by an analog peripheral, such as the ADC module or
Comparator module.
When the PORT register is read, all pins configured as
analog input channels are read as cleared (a low level).
Pins configured as digital inputs do not convert an
analog input. Analog levels on any pin defined as a
digital input (including the ANx pins) can cause the
input buffer to consume current that exceeds the
device specifications.
DS60001185B-page 168
I/O PORT WRITE/READ TIMING
One instruction cycle is required between a port
direction change or port write operation and a read
operation of the same port. Typically this instruction
would be an NOP.
12.1.4
INPUT CHANGE NOTIFICATION
The input change notification function of the I/O ports
allows the PIC32MX330/350/370/430/450/470 devices
to generate interrupt requests to the processor in
response to a change-of-state on selected input pins.
This feature can detect input change-of-states even in
Sleep mode, when the clocks are disabled. Every I/O
port pin can be selected (enabled) for generating an
interrupt request on a change-of-state.
Five control registers are associated with the CN functionality of each I/O port. The CNENx registers contain
the CN interrupt enable control bits for each of the input
pins. Setting any of these bits enables a CN interrupt
for the corresponding pins.
The CNSTATx register indicates whether a change
occurred on the corresponding pin since the last read
of the PORTx bit.
Each I/O pin also has a weak pull-up and every I/O
pin has a weak pull-down connected to it. The pullups act as a current source or sink source connected
to the pin, and eliminate the need for external
resistors when push-button or keypad devices are
connected. The pull-ups and pull-downs are enabled
separately using the CNPUx and the CNPDx
registers, which contain the control bits for each of the
pins. Setting any of the control bits enables the weak
pull-ups and/or pull-downs for the corresponding pins.
Note:
Pull-ups and pull-downs on change notification pins should always be disabled
when the port pin is configured as a digital
output.
An additional control register (CNCONx) is shown in
Register 12-3.
12.2
CLR, SET, and INV Registers
Every I/O module register has a corresponding CLR
(clear), SET (set) and INV (invert) register designed to
provide fast atomic bit manipulations. As the name of
the register implies, a value written to a SET, CLR or
INV register effectively performs the implied operation,
but only on the corresponding base register and only
bits specified as ‘1’ are modified. Bits specified as ‘0’
are not modified.
Reading SET, CLR and INV registers returns undefined
values. To see the affects of a write operation to a SET,
CLR or INV register, the base register must be read.

12.3
Peripheral Pin Select
A major challenge in general purpose devices is providing the largest possible set of peripheral features while
minimizing the conflict of features on I/O pins. The challenge is even greater on low pin-count devices. In an
application where more than one peripheral needs to
be assigned to a single pin, inconvenient workarounds
in application code or a complete redesign may be the
only option.
Peripheral pin select configuration provides an
alternative to these choices by enabling peripheral set
selection and their placement on a wide range of I/O
pins. By increasing the pinout options available on a
particular device, users can better tailor the device to
their entire application, rather than trimming the
application to fit the device.
The peripheral pin select configuration feature operates over a fixed subset of digital I/O pins. Users may
independently map the input and/or output of most digital peripherals to these I/O pins. Peripheral pin select
is performed in software and generally does not require
the device to be reprogrammed. Hardware safeguards
are included that prevent accidental or spurious
changes to the peripheral mapping once it has been
established.
12.3.1
AVAILABLE PINS
The number of available pins is dependent on the
particular device and its pin count. Pins that support the
peripheral pin select feature include the designation
“RPn” in their full pin designation, where “RP”
designates a remappable peripheral and “n” is the
remappable port number.
12.3.2
When a remappable peripheral is active on a given I/O
pin, it takes priority over all other digital I/O and digital
communication peripherals associated with the pin.
Priority is given regardless of the type of peripheral that
is mapped. Remappable peripherals never take priority
over any analog functions associated with the pin.
12.3.3
Peripheral pin select features are controlled through
two sets of SFRs: one to map peripheral inputs, and
one to map outputs. Because they are separately controlled, a particular peripheral’s input and output (if the
peripheral has both) can be placed on any selectable
function pin without constraint.
The association of a peripheral to a peripheral-selectable pin is handled in two different ways, depending on
whether an input or output is being mapped.
12.3.4
INPUT MAPPING
The inputs of the peripheral pin select options are
mapped on the basis of the peripheral. That is, a control
register associated with a peripheral dictates the pin it
will be mapped to. The [pin name]R registers, where [pin
name] refers to the peripheral pins listed in Table 12-1,
are used to configure peripheral input mapping (see
Register 12-1). Each register contains sets of 4 bit
fields. Programming these bit fields with an appropriate
value maps the RPn pin with the corresponding value to
that peripheral. For any given device, the valid range of
values for any bit field is shown in Table 12-1.
For example, Figure 12-2 illustrates the remappable
pin selection for the U1RX input.
FIGURE 12-2:
AVAILABLE PERIPHERALS
The peripherals managed by the peripheral pin select
are all digital-only peripherals. These include general
serial communications (UART and SPI), general purpose timer clock inputs, timer-related peripherals (input
capture and output compare) and interrupt-on-change
inputs.
REMAPPABLE INPUT
EXAMPLE FOR U1RX
U1RXR<3:0>

In comparison, some digital-only peripheral modules
are never included in the peripheral pin select feature.
This is because the peripheral’s function requires special I/O circuitry on a specific port and cannot be easily
connected to multiple pins. These modules include I2C
among others. A similar requirement excludes all modules with analog inputs, such as the Analog-to-Digital
Converter (ADC).
RPB6
A key difference between remappable and non-remappable peripherals is that remappable peripherals are
not associated with a default I/O pin. The peripheral
must always be assigned to a specific I/O pin before it
can be used. In contrast, non-remappable peripherals
are always available on a default pin, assuming that the
peripheral is active and not conflicting with another
peripheral.

Note:
Preliminary
For input only, peripheral pin select functionality
does not have priority over TRISx settings.
Therefore, when configuring RPn pin for input,
the corresponding bit in the TRISx register must
also be configured for input (set to ‘1’).

OUTPUT MAPPING
12.3.6.1
In contrast to inputs, the outputs of the peripheral pin
select options are mapped on the basis of the pin. In
this case, a control register associated with a
particular pin dictates the peripheral output to be
mapped. The RPnR registers (Register 12-2) are
used to control output mapping. Like the [pin name]R
registers, each register contains sets of 4 bit fields.
The value of the bit field corresponds to one of the
peripherals, and that peripheral’s output is mapped
to the pin (see Table 12-2 and Figure 12-3).
A null output is associated with the output register reset
value of ‘0’. This is done to ensure that remappable
outputs remain disconnected from all output pins by
default.

Control Register Lock
Under normal operation, writes to the RPnR and [pin
name]R registers are not allowed. Attempted writes
appear to execute normally, but the contents of the
registers remain unchanged. To change these registers, they must be unlocked in hardware. The register lock is controlled by the IOLOCK Configuration bit
(CFGCON<13>). Setting IOLOCK prevents writes to
the control registers; clearing IOLOCK allows writes.
To set or clear the IOLOCK bit, an unlock sequence
must be executed. Refer to Section 6. “Oscillator”
(DS60001112) in the “PIC32 Family Reference
Manual” for details.
12.3.6.2
Configuration Bit Select Lock
As an additional level of safety, the device can be
configured to prevent more than one write session to
the RPnR and [pin name]R registers. The IOL1WAY
Configuration bit (DEVCFG3<29>) blocks the IOLOCK
bit from being cleared after it has been set once. If
IOLOCK remains set, the register unlock procedure
does not execute, and the peripheral pin select control
registers cannot be written to. The only way to clear the
bit and re-enable peripheral remapping is to perform a
device Reset.
In the default (unprogrammed) state, IOL1WAY is set,
restricting users to one write session.

CONTROLLING CONFIGURATION
CHANGES
Because peripheral remapping can be changed during
run time, some restrictions on peripheral remapping
are needed to prevent accidental configuration
changes. PIC32 devices include two features to
prevent alterations to the peripheral map:
• Control register lock sequence
• Configuration bit select lock

Note 1: This data sheet summarizes the features
of the PIC32MX330/350/370/430/450/
470 family of devices. It is not intended to
be a comprehensive reference source.
To complement the information in this
data sheet, refer to Section 15. “Input
Capture” (DS60001122) of the “PIC32
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com/PIC32).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
Each input capture channel can select between one of
two 16-bit timers (Timer2 or Timer3) for the time base,
or two 16-bit timers (Timer2 and Timer3) together to
form a 32-bit timer. The selected timer can use either
an internal or external clock.
The Input Capture module is useful in applications
requiring frequency (period) and pulse measurement.
Other operational features include:
The Input Capture module captures the 16-bit or 32-bit
value of the selected Time Base registers when an
event occurs at the ICx pin. The following events cause
capture events:
FIGURE 15-1:
• Device wake-up from capture pin during CPU
Sleep and Idle modes
• Interrupt on input capture event
• 4-word FIFO buffer for capture values
Interrupt optionally generated after 1, 2, 3 or 4
buffer locations are filled
• Input capture can also be used to provide
additional sources of external interrupts

The Output Compare module (OCMP) is used to generate a single pulse or a train of pulses in response to
selected time base events. For all modes of operation,
the OCMP module compares the values stored in the
OCxR and/or the OCxRS registers to the value in the
selected timer. When a match occurs, the OCMP
module generates an event based on the selected
mode of operation.

This bit can only be written when the ON bit = 0.
This bit is not used in the Framed SPI mode. The user should program this bit to ‘0’ for the Framed SPI
mode (FRMEN = 1).
When AUDEN = 1, the SPI module functions as if the CKP bit is equal to ‘1’, regardless of the actual value
of CKP.

CIRCUIT™ (I2C™)
Note 1: This data sheet summarizes the
features of the PIC32MX330/350/370/
430/450/470 family of devices. It is not
intended to be a comprehensive
reference source. To complement the
information in this data sheet, refer to
Section 24. “Inter-Integrated Circuit™
(I2C™)” (DS60001116) in the “PIC32
Family Reference Manual”, which is
available from the Microchip web site
(www.microchip.com/PIC32).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.

The I2C module provides complete hardware support
for both Slave and Multi-Master modes of the I2C serial
communication standard. Figure 18-1 illustrates the
I2C module block diagram.
Each I2C module has a 2-pin interface: the SCLx pin is
clock and the SDAx pin is data.
Each I2C module offers the following key features:
• I2C interface supporting both master and slave
operation
• I2C Slave mode supports 7-bit and 10-bit addressing
• I2C Master mode supports 7-bit and 10-bit
addressing
• I2C port allows bidirectional transfers between
master and slaves
• Serial clock synchronization for the I2C port can
be used as a handshake mechanism to suspend
and resume serial transfer (SCLREL control)
• I2C supports multi-master operation; detects bus
collision and arbitrates accordingly
• Provides support for address bit masking

3:
When using 1:1 PBCLK divisor, the user’s software should not read/write the peripheral’s SFRs in the
SYSCLK cycle immediately following the instruction that clears the module’s ON bit.
If ASAM = 0, software can write a ‘1’ to start sampling. This bit is automatically set by hardware if
ASAM = 1. If SSRC = 0, software can write a ‘0’ to end sampling and start conversion. If SSRC ‘0’, this
bit is automatically cleared by hardware to end sampling and start conversion.
This bit is automatically set by hardware when analog-to-digital conversion is complete. Software can
write a ‘0’ to clear this bit (a write of ‘1’ is not allowed). Clearing this bit does not affect any operation
already in progress. This bit is automatically cleared by hardware at the start of a new conversion.

The CVREF module is a 16-tap, resistor ladder network
that provides a selectable reference voltage. Although
its primary purpose is to provide a reference for the
analog comparators, it also may be used independently
of them.

A block diagram of the module is illustrated in
Figure 24-1. The resistor ladder is segmented to
provide two ranges of voltage reference values and has
a power-down function to conserve power when the
reference is not being used. The module’s supply reference can be provided from either device VDD/VSS or an
external voltage reference. The CVREF output is available for the comparators and typically available for pin

POWER-SAVING FEATURES
Note 1: This data sheet summarizes the features
of the PIC32MX330/350/370/430/450/
470 family of devices. It is not intended to
be a comprehensive reference source. To
complement the information in this data
sheet, refer to Section 10. “PowerSaving Features” (DS60001130) in the
“PIC32 Family Reference Manual”, which
is available from the Microchip web site
(www.microchip.com/PIC32).
2: Some registers and associated bits
described in this section may not be
available on all devices. Refer to
Section 4.0 “Memory Organization” in
this data sheet for device-specific register
and bit information.
This section describes power-saving features for the
PIC32MX330/350/370/430/450/470. The PIC32 devices
offer a total of nine methods and modes, organized into
two categories, that allow the user to balance power
consumption with device performance. In all of the
methods and modes described in this section, powersaving is controlled by software.
26.1
Power Saving with CPU Running
When the CPU is running, power consumption can be
controlled by reducing the CPU clock frequency,
lowering the PBCLK and by individually disabling
modules. These methods are grouped into the
following categories:
• FRC Run mode: the CPU is clocked from the FRC
clock source with or without postscalers.
• LPRC Run mode: the CPU is clocked from the
LPRC clock source.
• SOSC Run mode: the CPU is clocked from the
SOSC clock source.
In addition, the Peripheral Bus Scaling mode is available
where peripherals are clocked at the programmable
fraction of the CPU clock (SYSCLK).
26.2
CPU Halted Methods
The device supports two power-saving modes, Sleep
and Idle, both of which Halt the clock to the CPU. These
modes operate with all clock sources, as listed below:
• POSC Idle mode: the system clock is derived from
the POSC. The system clock source continues to
operate. Peripherals continue to operate, but can
optionally be individually disabled.
• FRC Idle mode: the system clock is derived from
the FRC with or without postscalers. Peripherals
continue to operate, but can optionally be
individually disabled.
• SOSC Idle mode: the system clock is derived from
the SOSC. Peripherals continue to operate, but
can optionally be individually disabled.
 2012-2013 Microchip Technology Inc.
• LPRC Idle mode: the system clock is derived from
the LPRC. Peripherals continue to operate, but
can optionally be individually disabled. This is the
lowest power mode for the device with a clock
running.
• Sleep mode: the CPU, the system clock source
and any peripherals that operate from the system
clock source are Halted. Some peripherals can
operate in Sleep using specific clock sources.
This is the lowest power mode for the device.
26.3
Power-Saving Operation
Peripherals and the CPU can be Halted or disabled to
further reduce power consumption.
26.3.1
SLEEP MODE
Sleep mode has the lowest power consumption of the
device power-saving operating modes. The CPU and
most peripherals are Halted. Select peripherals can
continue to operate in Sleep mode and can be used to
wake the device from Sleep. See the individual
peripheral module sections for descriptions of
behavior in Sleep.
Sleep mode includes the following characteristics:
• The CPU is Halted.
• The system clock source is typically shutdown.
See Section 26.3.3 “Peripheral Bus Scaling
Method” for specific information.
• There can be a wake-up delay based on the
oscillator selection.
• The Fail-Safe Clock Monitor (FSCM) does not
operate during Sleep mode.
• The BOR circuit remains operative during Sleep
mode.
• The WDT, if enabled, is not automatically cleared
prior to entering Sleep mode.
• Some peripherals can continue to operate at
limited functionality in Sleep mode. These
peripherals include I/O pins that detect a change
in the input signal, WDT, ADC, UART and
peripherals that use an external clock input or the
internal LPRC oscillator (e.g., RTCC, Timer1 and
Input Capture).
• I/O pins continue to sink or source current in the
same manner as they do when the device is not in
Sleep.
• The USB module can override the disabling of the
Posc or FRC. Refer to the USB section for
specific details.
• Modules can be individually disabled by software
prior to entering Sleep in order to further reduce
consumption.
Preliminary
DS60001185B-page 247
PIC32MX330/350/370/430/450/470
The processor will exit, or ‘wake-up’, from Sleep on one
of the following events:
• On any interrupt from an enabled source that is
operating in Sleep. The interrupt priority must be
greater than the current CPU priority.
• On any form of device Reset.
• On a WDT time-out.
The processor will wake or exit from Idle mode on the
following events:
If the interrupt priority is lower than or equal to the
current priority, the CPU will remain Halted, but the
PBCLK will start running and the device will enter into
Idle mode.
26.3.2
IDLE MODE
In Idle mode, the CPU is Halted but the System Clock
(SYSCLK) source is still enabled. This allows peripherals to continue operation when the CPU is Halted.
Peripherals can be individually configured to Halt when
entering Idle by setting their respective SIDL bit.
Latency, when exiting Idle mode, is very low due to the
CPU oscillator source remaining active.
Note 1: Changing the PBCLK divider ratio
requires recalculation of peripheral timing. For example, assume the UART is
configured for 9600 baud with a PB clock
ratio of 1:1 and a POSC of 8 MHz. When
the PB clock divisor of 1:2 is used, the
input frequency to the baud clock is cut in
half; therefore, the baud rate is reduced
to 1/2 its former value. Due to numeric
truncation in calculations (such as the
baud rate divisor), the actual baud rate
may be a tiny percentage different than
expected. For this reason, any timing calculation required for a peripheral should
be performed with the new PB clock frequency instead of scaling the previous
value based on a change in the PB divisor
ratio.
2: Oscillator start-up and PLL lock delays
are applied when switching to a clock
source that was disabled and that uses a
crystal and/or the PLL. For example,
assume the clock source is switched from
POSC to LPRC just prior to entering Sleep
in order to save power. No oscillator startup delay would be applied when exiting
Idle. However, when switching back to
POSC, the appropriate PLL and/or
oscillator start-up/lock delays would be
applied.
DS60001185B-page 248
The device enters Idle mode when the SLPEN bit
(OSCCON<4>) is clear and a WAIT instruction is
executed.
• On any interrupt event for which the interrupt
source is enabled. The priority of the interrupt
event must be greater than the current priority of
the CPU. If the priority of the interrupt event is
lower than or equal to current priority of the CPU,
the CPU will remain Halted and the device will
remain in Idle mode.
• On any form of device Reset
• On a WDT time-out interrupt
26.3.3
PERIPHERAL BUS SCALING
METHOD
Most of the peripherals on the device are clocked using
the PBCLK. The peripheral bus can be scaled relative to
the SYSCLK to minimize the dynamic power consumed
by the peripherals. The PBCLK divisor is controlled by
PBDIV<1:0> (OSCCON<20:19>), allowing SYSCLK to
PBCLK ratios of 1:1, 1:2, 1:4 and 1:8. All peripherals
using PBCLK are affected when the divisor is changed.
Peripherals such as the USB, Interrupt Controller, DMA,
and the bus matrix are clocked directly from SYSCLK.
As a result, they are not affected by PBCLK divisor
changes.
Changing the PBCLK divisor affects:
• The CPU to peripheral access latency. The CPU
has to wait for next PBCLK edge for a read to
complete. In 1:8 mode, this results in a latency of
one to seven SYSCLKs.
• The power consumption of the peripherals. Power
consumption is directly proportional to the frequency at which the peripherals are clocked. The
greater the divisor, the lower the power consumed
by the peripherals.
To minimize dynamic power, the PB divisor should be
chosen to run the peripherals at the lowest frequency
that provides acceptable system performance. When
selecting a PBCLK divider, peripheral clock requirements, such as baud rate accuracy, should be taken
into account. For example, the UART peripheral may
not be able to achieve all baud rate values at some
PBCLK divider depending on the SYSCLK value.

To disable a peripheral, the associated PMDx bit must
be set to ‘1’. To enable a peripheral, the associated
PMDx bit must be cleared (default). See Table 26-1 for
more information.
Peripheral Module Disable
The Peripheral Module Disable (PMD) registers
provide a method to disable a peripheral module by
stopping all clock sources supplied to that module.
When a peripheral is disabled using the appropriate
PMD control bit, the peripheral is in a minimum power
consumption state. The control and status registers
associated with the peripheral are also disabled, so
writes to those registers do not have effect and read
values are invalid.
TABLE 26-1:
Note:
Disabling a peripheral module while it’s
ON bit is set, may result in undefined
behavior. The ON bit for the associated
peripheral module must be cleared prior to
disable a module via the PMDx bits.

26.4.1
CONTROLLING CONFIGURATION
CHANGES
Because peripherals can be disabled during run time,
some restrictions on disabling peripherals are needed
to prevent accidental configuration changes. PIC32
devices include two features to prevent alterations to
enabled or disabled peripherals:
• Control register lock sequence
• Configuration bit select lock
26.4.1.1
Control Register Lock
Under normal operation, writes to the PMDx registers
are not allowed. Attempted writes appear to execute
normally, but the contents of the registers remain
unchanged. To change these registers, they must be
unlocked in hardware. The register lock is controlled by
the PMDLOCK Configuration bit (CFGCON<12>). Setting PMDLOCK prevents writes to the control registers; 
clearing PMDLOCK allows writes.
To set or clear PMDLOCK, an unlock sequence must
be executed. Refer to Section 6. “Oscillator”
(DS60001112) in the “PIC32 Family Reference
Manual” for details.
26.4.1.2
Configuration Bit Select Lock
As an additional level of safety, the device can be
configured to prevent more than one write session to
the PMDx registers. The PMDL1WAY Configuration bit
(DEVCFG3<28>) blocks the PMDLOCK bit from being
cleared after it has been set once. If PMDLOCK
remains set, the register unlock procedure does not
execute, and the peripheral pin select control registers
cannot be written to. The only way to clear the bit and
re-enable PMD functionality is to perform a device
Reset.

Watchdog Timer (WDT)
This section describes the operation of the WDT and
Power-up Timer of the PIC32MX330/350/370/430/450/
470.
The WDT, when enabled, operates from the internal
Low-Power Oscillator (LPRC) clock source and can be
used to detect system software malfunctions by resetting the device if the WDT is not cleared periodically in
software. Various WDT time-out periods can be
selected using the WDT postscaler. The WDT can also
be used to wake the device from Sleep or Idle mode.
FIGURE 27-1:
The following are some of the key features of the WDT
module:
• Configuration or software controlled
• User-configurable time-out period
• Can wake the device from Sleep or Idle

On-Chip Voltage Regulator
27.4
All PIC32MX330/350/370/430/450/470 devices’ core
and digital logic are designed to operate at a nominal
1.8V. To simplify system designs, most devices in the
PIC32MX330/350/370/430/450/470 family incorporate
an on-chip regulator providing the required core logic
voltage from VDD.
A low-ESR capacitor (such as tantalum) must be
connected to the VCAP pin (see Figure 27-2). This
helps to maintain the stability of the regulator. The
recommended value for the filter capacitor is provided
in Section 30.1 “DC Characteristics”.
It is important that the low-ESR capacitor
is placed as close as possible to the VCAP
pin.
Note:
27.3.1
HIGH VOLTAGE DETECT (HVD)
The HVD module monitors the core voltage at the VCAP
pin. If a voltage above the required level is detected on
VCAP, the I/O pins are disabled and the device is held
in Reset as long as the HVD condition persists. See
parameter HV10 (VHVD) in Table 30-11 in Section 30.1
“DC Characteristics” for more information.
27.3.2
Programming and Diagnostics
PIC32MX330/350/370/430/450/470 devices provide a
complete range of programming and diagnostic features that can increase the flexibility of any application
using them. These features allow system designers to
include:
• Simplified field programmability using two-wire 
In-Circuit Serial Programming™ (ICSP™)
interfaces
• Debugging using ICSP
• Programming and debugging capabilities using
the EJTAG extension of JTAG
• JTAG boundary scan testing for device and board
diagnostics
PIC32 devices incorporate two programming and diagnostic modules, and a trace controller, that provide a
range of functions to the application developer.

It takes a fixed delay for the on-chip regulator to generate
an output. During this time, designated as TPU, code
execution is disabled. TPU is applied every time the
device resumes operation after any power-down,

PIC32MX330/350/370/430/450/470 devices also have
a simple brown-out capability. If the voltage supplied to
the regulator is inadequate to maintain a regulated
level, the regulator Reset circuitry will generate a
Brown-out Reset. This event is captured by the BOR
flag bit (RCON<1>). The brown-out voltage levels are
specific in Section 30.1 “DC Characteristics”.

external square wave from rail-to-rail, (OSC1 input clock input over/undershoot < 100 mV required)
• OSC2/CLKO is configured as an I/O input pin
• USB PLL oscillator is disabled if the USB module is implemented, PBCLK divisor = 1:8
• CPU is in Sleep mode, program Flash memory Wait states = 7, Program Cache and Prefetch are disabled and SRAM data memory Wait states = 1
• No peripheral modules are operating, (ON bit = 0), but the associated PMD bit is set
• WDT, Clock Switching, Fail-Safe Clock Monitor, and Secondary Oscillator are disabled
• All I/O pins are configured as inputs and pulled to VSS
• MCLR = VDD
• RTCC and JTAG are disabled
• Voltage regulator is off during Sleep mode (VREGS bit in the RCON register = 0)
Data in the “Typical” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance
only and are not tested.
The  current is the additional current consumed when the module is enabled. This current should be
added to the base IPD current.
Test conditions for ADC module differential current are as follows: Internal ADC RC oscillator enabled.

Note 1: Data in “Typical” column is at 3.3V, 25°C unless otherwise stated. Parameters are for design guidance only
and are not tested.
2: The leakage current on the MCLR pin is strongly dependent on the applied voltage level. The specified
levels represent normal operating conditions. Higher leakage current may be measured at different input
voltages.
3: Negative current is defined as current sourced by the pin.
4: This parameter is characterized, but not tested in manufacturing.
5: See the “Pin Diagrams” section for the 5V tolerant pins.
6: The VIH specifications are only in relation to externally applied inputs, and not with respect to the userselectable internal pull-ups. External open drain input signals utilizing the internal pull-ups of the PIC32
device are guaranteed to be recognized only as a logic “high” internally to the PIC32 device, provided
that the external load does not exceed the minimum value of ICNPU. For External “input” logic inputs that
require a pull-up source, to guarantee the minimum VIH of those components, it is recommended to use
an external pull-up resistor rather than the internal pull-ups of the PIC32 device.
7: VIL source < (VSS - 0.3). Characterized but not tested.
8: VIH source > (VDD + 0.3) for non-5V tolerant pins only.
9: Digital 5V tolerant pins do not have an internal high side diode to VDD, and therefore, cannot tolerate any
“positive” input injection current.
10: Injection currents > | 0 | can affect the ADC results by approximately 4 to 6 counts (i.e., VIH Source > (VDD
+ 0.3) or VIL source < (VSS - 0.3)).
11: Any number and/or combination of I/O pins not excluded under IICL or IICH conditions are permitted provided the “absolute instantaneous” sum of the input injection currents from all pins do not exceed the specified limit. If Note 7, IICL = (((Vss - 0.3) - VIL source) / Rs). If Note 8, IICH = ((IICH source - (VDD + 0.3)) /
RS). RS = Resistance between input source voltage and device pin. If (VSS - 0.3)  VSOURCE  (VDD +
0.3), injection current = 0.

The minimum SYSCLK for row programming is 8 MHz. Care should be taken to minimize bus activities
during row programming, such as suspending any memory-to-memory DMA operations. If heavy bus loads
are expected, selecting Bus Matrix Arbitration mode 2 (rotating priority) may be necessary. The default
Arbitration mode is mode 1 (CPU has lowest priority).

Data in “Typical” column is at 3.3V, 25°C unless otherwise stated. Parameters are characterized but are not
tested.
Instruction cycle period (TCY) equals the input oscillator time base period. All specified values are based on
characterization data for that particular oscillator type under standard operating conditions with the device
executing code. Exceeding these specified limits may result in an unstable oscillator operation and/or
higher than expected current consumption. All devices are tested to operate at “min.” values with an
external clock applied to the OSC1/CLKI pin.

This jitter specification is based on clock-cycle by clock-cycle measurements. To get the effective jitter for
individual time-bases on communication clocks, use the following formula:
D CLK
EffectiveJitter = -------------------------------------------------------------SYSCLK
--------------------------------------------------------CommunicationClock
For example, if SYSCLK = 40 MHz and SPI bit rate = 20 MHz, the effective jitter is as follows:

These parameters are characterized, but not tested in manufacturing.
Because the sample caps will eventually lose charge, clock rates below 10 kHz can affect linearity
performance, especially at elevated temperatures.
Characterized by design but not tested.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
