4. PSoC Functional Overview
The PSoC family consists of many devices with on-chip
controllers. These devices are designed to replace multiple
traditional MCU-based system components with one low-cost
single-chip programmable component. A PSoC device includes
configurable blocks of analog and digital logic, and
programmable interconnect. This architecture makes it possible
for you to create customized peripheral configurations, to match
the requirements of each individual application. Additionally, a
fast central processing unit (CPU), flash program memory,
SRAM data memory, and configurable I/O are included in a
range of convenient pinouts.
4.2 The Digital System
The digital system consists of four digital PSoC blocks. Each
block is an 8-bit resource that is used alone or combined with
other blocks to form 8-, 16-, 24-, and 32-bit peripherals, which
are called user modules. Digital peripheral configurations
include:
■
PWMs (8- to 32-bit)
■
PWMs with dead band (8- to 32-bit)
■
Counters (8- to 32-bit)
■
Timers (8- to 32-bit)
■
UART 8-bit with selectable parity
■
SPI master and slave
■
I2C slave and multi-master
■
CRC/generator (8-bit)
■
IrDA
4.1 The PSoC Core
■
PRS generators (8- to 32-bit)
The PSoC core is a powerful engine that supports a rich
instruction set. It encompasses SRAM for data storage, an
interrupt controller, sleep and watchdog timers, and internal main
oscillator (IMO) and internal low-speed oscillator (ILO). The CPU
core, called the M8C, is a powerful processor with speeds up to
24 MHz. The M8C is a four-million instructions per second
(MIPS) 8-bit Harvard-architecture microprocessor.
The digital blocks are connected to any GPIO through a series
of global buses that can route any signal to any pin. The buses
also allow for signal multiplexing and for performing logic
operations. This configurability frees your designs from the
constraints of a fixed peripheral controller.
The PSoC architecture, shown in “Logic Block Diagram” on
page 1, consists of four main areas: the core, the system
resources, the digital system, and the analog system.
Configurable global bus resources allow combining all of the
device resources into a complete custom system. Each
CY8C24x94 PSoC device includes four digital blocks and six
analog blocks. Depending on the PSoC package, up to 56
GPIOs are also included. The GPIOs provide access to the
global digital and analog interconnects.
■
Digital clocks for increased flexibility
Digital blocks are provided in rows of four, where the number of
blocks varies by PSoC device family. This allows the optimum
choice of system resources for your application. Family
resources are shown in Table 1 on page 5.

4.3 The Analog System
The analog system is composed of six configurable blocks, each
comprised of an opamp circuit allowing the creation of complex
analog signal flows. Analog peripherals are very flexible and can
be customized to support specific application requirements.
Some of the more common PSoC analog functions (most
available as user modules) are as follows.

4.3.1 The Analog Multiplexer System
The analog mux bus can connect to every GPIO pin in ports 0–5.
Pins are connected to the bus individually or in any combination.
The bus also connects to the analog system for analysis with
comparators and analog-to-digital converters. It is split into two
sections for simultaneous dual-channel processing. An
additional 8:1 analog input multiplexer provides a second path to
bring Port 0 pins to the analog array.
Switch-control logic enables selected pins to precharge continuously under hardware control. This enables capacitive
measurement for applications such as touch sensing. Other
multiplexer applications include:

complete systems. Additional resources include a multiplier,
decimator, low-voltage detection, and power-on reset (POR).
Brief statements describing the merits of each resource follow.
■
■
■
Full speed USB (12 Mbps) with five configurable endpoints and
256 bytes of RAM. No external components required except
for two series resistors. Wider than commercial temperature
USB operation (–10 °C to +85 °C).
Digital clock dividers provide three customizable clock
frequencies for use in applications. The clocks can be routed
to both the digital and analog systems. Additional clocks are
generated using digital PSoC blocks as clock dividers.
■
Decimator provides a custom hardware filter for digital signal
processing applications including creation of Delta Sigma
ADCs.
■
The I2C module provides 100- and 400-kHz communication
over two wires. Slave, master, multi-master are supported.
■
Low-voltage detection interrupts signal the application of falling
voltage levels, while the advanced POR circuit eliminates the
need for a system supervisor.
■
An internal 1.3-V reference provides an absolute reference for
the analog system, including ADCs and DACs.
■
Versatile analog multiplexer system.
Two multiply accumulates (MACs) provide fast 8-bit multipliers
with 32-bit accumulate, to assist in both general math and
digital filters.

6. Development Tools
PSoC Designer™ is the revolutionary Integrated Design
Environment (IDE) that you can use to customize PSoC to meet
your specific application requirements. PSoC Designer software
accelerates system design and time to market. Develop your
applications using a library of precharacterized analog and digital
peripherals (called user modules) in a drag-and-drop design
environment. Then, customize your design by leveraging the
dynamically generated application programming interface (API)
libraries of code. Finally, debug and test your designs with the
integrated debug environment, including in-circuit emulation and
standard software debug features. PSoC Designer includes:
■
Application editor graphical user interface (GUI) for device and
user module configuration and dynamic reconfiguration
■
Extensive user module catalog
■
Integrated source-code editor (C and assembly)
■
Free C compiler with no size restrictions or time limits
■
Built-in debugger
■
In-circuit emulation
■
Built-in support for communication interfaces:
2
❐ Hardware and software I C slaves and masters
❐ Full speed USB 2.0
❐ Up to four full-duplex universal asynchronous receiver/transmitters (UARTs), SPI master and slave, and wireless
PSoC Designer supports the entire library of PSoC 1 devices and
runs on Windows XP, Windows Vista, and Windows 7.
6.1 PSoC Designer Software Subsystems
6.1.1 Design Entry
In the chip-level view, choose a base device to work with. Then
select different onboard analog and digital components that use
Document Number: 38-12018 Rev. AD
the PSoC blocks, which are called user modules. Examples of
user modules are analog-to-digital converters (ADCs),
digital-to-analog converters (DACs), amplifiers, and filters.
Configure the user modules for your chosen application and
connect them to each other and to the proper pins. Then
generate your project. This prepopulates your project with APIs
and libraries that you can use to program your application.
The tool also supports easy development of multiple configurations and dynamic reconfiguration. Dynamic reconfiguration
makes it possible to change configurations at run time. In
essence, this allows you to use more than 100 percent of PSoC's
resources for an application.
6.1.2 Code Generation Tools
The code generation tools work seamlessly within the
PSoC Designer interface and have been tested with a full range
of debugging tools. You can develop your design in C, assembly,
or a combination of the two.
Assemblers. The assemblers allow you to merge assembly
code seamlessly with C code. Link libraries automatically use
absolute addressing or are compiled in relative mode, and are
linked with other software modules to get absolute addressing.
C Language Compilers. C language compilers are available
that support the PSoC family of devices. The products allow you
to create complete C programs for the PSoC family devices. The
optimizing C compilers provide all of the features of C, tailored
to the PSoC architecture. They come complete with embedded
libraries providing port and bus operations, standard keypad and
display support, and extended math functionality.
6.1.3 Debugger
PSoC Designer has a debug environment that provides
hardware in-circuit emulation, allowing you to test the program in
a physical system while providing an internal view of the PSoC
device. Debugger commands allow you to read and program and
Page 6 of 61
CY8C24094, CY8C24794
CY8C24894, CY8C24994
read and write data memory, and read and write I/O registers.
You can read and write CPU registers, set and clear breakpoints,
and provide program run, halt, and step control. The debugger
also allows you to create a trace buffer of registers and memory
locations of interest.
6.1.4 Online Help System
The online help system displays online, context-sensitive help.
Designed for procedural and quick reference, each functional
subsystem has its own context-sensitive help. This system also
provides tutorials and links to FAQs and an online support forum
to aid the designer.
6.1.5 In-Circuit Emulator
A low-cost, high-functionality In-Circuit Emulator (ICE) is
available for development support. This hardware can program
single devices.
The emulator consists of a base unit that connects to the PC
using a USB port. The base unit is universal and operates with
all PSoC devices. Emulation pods for each device family are
available separately. The emulation pod takes the place of the
PSoC device in the target board and performs full speed
(24-MHz) operation.
7. Designing with PSoC Designer
The development process for the PSoC® device differs from that
of a traditional fixed function microprocessor. The configurable
analog and digital hardware blocks give the PSoC architecture a
unique flexibility that pays dividends in managing specification
change during development and by lowering inventory costs.
These configurable resources, called PSoC Blocks, have the
ability to implement a wide variety of user-selectable functions.
The PSoC development process is summarized in four steps:
1. Select User Modules
2. Configure User Modules
3. Organize and Connect
4. Generate, Verify, and Debug
7.1 Select User Modules
PSoC Designer provides a library of prebuilt, pretested hardware
peripheral components called “user modules.” User modules
make selecting and implementing peripheral devices, both
analog and digital, simple.
7.2 Configure User Modules
Each user module that you select establishes the basic register
settings that implement the selected function. They also provide
parameters and properties that allow you to tailor their precise
configuration to your particular application. For example, a PWM
User Module configures one or more digital PSoC blocks, one
for each 8 bits of resolution. The user module parameters permit
you to establish the pulse width and duty cycle. Configure the
parameters and properties to correspond to your chosen application. Enter values directly or by selecting values from
drop-down menus. All the user modules are documented in
datasheets that may be viewed directly in PSoC Designer or on
the Cypress website. These user module datasheets explain the
internal operation of the user module and provide performance
specifications. Each datasheet describes the use of each user
module parameter, and other information you may need to
successfully implement your design.
Document Number: 38-12018 Rev. AD
7.3 Organize and Connect
You build signal chains at the chip level by interconnecting user
modules to each other and the I/O pins. You perform the
selection, configuration, and routing so that you have complete
control over all on-chip resources.
7.4 Generate, Verify, and Debug
When you are ready to test the hardware configuration or move
on to developing code for the project, you perform the “Generate
Configuration Files” step. This causes PSoC Designer to
generate source code that automatically configures the device to
your specification and provides the software for the system. The
generated code provides application programming interfaces
(APIs) with high-level functions to control and respond to
hardware events at run time and interrupt service routines that
you can adapt as needed.
A complete code development environment allows you to
develop and customize your applications in either C, assembly
language, or both.
The last step in the development process takes place inside
PSoC Designer’s debugger (access by clicking the Connect
icon). PSoC Designer downloads the HEX image to the ICE
where it runs at full speed. PSoC Designer debugging capabilities rival those of systems costing many times more. In addition
to traditional single-step, run-to-breakpoint, and watch-variable
features, the debug interface provides a large trace buffer and
allows you to define complex breakpoint events. These include
monitoring address and data bus values, memory locations and
external signals.

9. Register Reference
This section lists the registers of the CY8C24x94 PSoC device family. For detailed register information, see the
PSoC Technical Reference Manual.
9.1 Register Conventions
9.2 Register Mapping Tables
The register conventions specific to this section are listed in the
following table.
The PSoC device has a total register address space of
512 bytes. The register space is referred to as I/O space and is
divided into two banks, Bank 0 and Bank 1. The XOI bit in the
Flag register (CPU_F) determines which bank the user is
currently in. When the XOI bit is set to 1, the user is in Bank 1.
Convention
Description
R
Read register or bit(s)
W
Write register or bit(s)
L
Logical register or bit(s)
C
Clearable register or bit(s)
#
Access is bit specific

10.3.7 DC Analog Reference Specifications
The following tables list guaranteed maximum and minimum specifications for the voltage and temperature ranges: 4.75 V to 5.25 V
and –40 °C  TA  85 °C, or 3.0 V to 3.6 V and –40 °C  TA  85 °C, respectively. Typical parameters apply to 5 V and 3.3 V at 25 °C
and are for design guidance only.
The guaranteed specifications for RefHI and RefLo are measured through the Analog Continuous Time PSoC blocks. The power
levels for RefHi and RefLo refer to the Analog Reference Control register. AGND is measured at P2[4] in AGND bypass mode. Each
Analog Continuous Time PSoC block adds a maximum of 10mV additional offset error to guaranteed AGND specifications from the
local AGND buffer. Reference control power can be set to medium or high unless otherwise noted.
Note Avoid using P2[4] for digital signaling when using an analog resource that depends on the Analog Reference. Some coupling
of the digital signal may appear on the AGND.

17. The 50,000 cycle flash endurance per block is only guaranteed if the flash is operating within one voltage range. Voltage ranges are 3.0 V to 3.6 V and 4.75 V to 5.25 V.
18. A maximum of 36 × 50,000 block endurance cycles is allowed. This may be balanced between operations on 36 × 1 blocks of 50,000 maximum cycles each,
36 × 2 blocks of 25,000 maximum cycles each, or 36 × 4 blocks of 12,500 maximum cycles each (to limit the total number of cycles to 36 × 50,000 and ensure that
no single block ever sees more than 50,000 cycles).
For the full industrial range, the user must employ a temperature sensor user module (FlashTemp) and feed the result to the temperature argument before writing.
See the Flash APIs application note Design Aids – Reading and Writing PSoC® Flash – AN2015 for more information.
19. All GPIOs meet the DC GPIO VIL and VIH specifications found in the DC GPIO Specifications sections. The I2C GPIO pins also meet the mentioned specifications.

26. A fast-mode I2C-bus device can be used in a standard-mode I2C-bus system, but the requirement tSU;DAT 250 ns it must meet. This automatically is the case if the
device does not stretch the LOW period of the SCL signal. If the device does stretch the LOW period of the SCL signal, it must output the next data bit to the SDA line
trmax + tSU;DAT = 1000 + 250 = 1250 ns (according to the Standard-Mode I2C-bus specification) before the SCL line is released.

the negative temperature coefficient of VBE, to produce a zero temperature coefficient (ideally)
reference.
bandwidth
1. The frequency range of a message or information processing system measured in hertz.
2. The width of the spectral region over which an amplifier (or absorber) has substantial gain (or
loss); it is sometimes represented more specifically as, for example, full width at half maximum.
bias
1. A systematic deviation of a value from a reference value.

external to that process, and performed in such a way that the process can be resumed.
interrupt service
routine (ISR)
A block of code that normal code execution is diverted to when the M8C receives a hardware
interrupt. Many interrupt sources may each exist with its own priority and individual ISR code
block. Each ISR code block ends with the RETI instruction, returning the device to the point in
the program where it left normal program execution.

serial data streams.
2. The abrupt and unwanted variations of one or more signal characteristics, such as the interval between
successive pulses, the amplitude of successive cycles, or the frequency or phase of successive cycles.
low-voltage detect A circuit that senses VDD and provides an interrupt to the system when VDD falls lower than a

selected threshold.
M8C
An 8-bit Harvard-architecture microprocessor. The microprocessor coordinates all activity inside
a PSoC by interfacing to the Flash, SRAM, and register space.
master device
A device that controls the timing for data exchanges between two devices. Or when devices are
cascaded in width, the master device is the one that controls the timing for data exchanges
between the cascaded devices and an external interface. The controlled device is called the
slave device.

Glossary
(continued)
microcontroller
An integrated circuit chip that is designed primarily for control systems and products. In addition
to a CPU, a microcontroller typically includes memory, timing circuits, and IO circuitry. The reason
for this is to permit the realization of a controller with a minimal quantity of chips, thus
achieving maximal possible miniaturization. This in turn, reduces the volume and the cost of
the controller. The microcontroller is normally not used for general-purpose computation as is a
microprocessor.
mixed-signal
The reference to a circuit containing both analog and digital techniques and components.
modulator
A device that imposes a signal on a carrier.
noise
1. A disturbance that affects a signal and that may distort the information carried by the signal.
2. The random variations of one or more characteristics of any entity such as voltage, current, or data.
oscillator
A circuit that may be crystal controlled and is used to generate a clock frequency.
parity
A technique for testing transmitting data. Typically, a binary digit is added to the data to make the
sum of all the digits of the binary data either always even (even parity) or always odd (odd parity).
phase-locked
loop (PLL)
An electronic circuit that controls an oscillator so that it maintains a constant phase angle relative
to a reference signal.
pinouts
The pin number assignment: the relation between the logical inputs and outputs of the PSoC
device and their physical counterparts in the printed circuit board (PCB) package. Pinouts
involve pin numbers as a link between schematic and PCB design (both being computer generated
files) and may also involve pin names.
port
A group of pins, usually eight.
power on reset
(POR)
A circuit that forces the PSoC device to reset when the voltage is lower than a pre-set level. This is
one type of hardware reset.
PSoC®
Cypress Semiconductor’s PSoC® is a registered trademark and Programmable System-onChip™ is a trademark of Cypress.
PSoC Designer™ The software for Cypress’ Programmable System-on-Chip technology.
pulse width
An output in the form of duty cycle which varies as a function of the applied measurand
modulator (PWM)
RAM
An acronym for random access memory. A data-storage device from which data can be read out
and new data can be written in.
register
A storage device with a specific capacity, such as a bit or byte.
reset
A means of bringing a system back to a know state. See hardware reset and software reset.
ROM
An acronym for read only memory. A data-storage device from which data can be read out, but
new data cannot be written in.
serial
1. Pertaining to a process in which all events occur one after the other.
2. Pertaining to the sequential or consecutive occurrence of two or more related activities in a single device or
channel.

settling time
The time it takes for an output signal or value to stabilize after the input has changed from one
value to another.
shift register
A memory storage device that sequentially shifts a word either left or right to output a stream of
serial data.
slave device
A device that allows another device to control the timing for data exchanges between two
devices. Or when devices are cascaded in width, the slave device is the one that allows another
device to control the timing of data exchanges between the cascaded devices and an external
interface. The controlling device is called the master device.
SRAM
An acronym for static random access memory. A memory device allowing users to store and
retrieve data at a high rate of speed. The term static is used because, after a value has been
loaded into an SRAM cell, it remains unchanged until it is explicitly altered or until power is
removed from the device.
SROM
An acronym for supervisory read only memory. The SROM holds code that is used to boot the
device, calibrate circuitry, and perform Flash operations. The functions of the SROM may be
accessed in normal user code, operating from Flash.
stop bit
A signal following a character or block that prepares the receiving device to receive the next
character or block.
synchronous
1. A signal whose data is not acknowledged or acted upon until the next active edge of a clock signal.
2. A system whose operation is synchronized by a clock signal.
tristate
A function whose output can adopt three states: 0, 1, and Z (high-impedance). The function does
not drive any value in the Z state and, in many respects, may be considered to be disconnected
from the rest of the circuit, allowing another output to drive the same net.
UART
A UART or universal asynchronous receiver-transmitter translates between parallel bits of data
and serial bits.
user modules
Pre-build, pre-tested hardware/firmware peripheral functions that take care of managing and
configuring the lower level Analog and Digital PSoC Blocks. User Modules also provide high
level API (Application Programming Interface) for the peripheral function.
user space
The bank 0 space of the register map. The registers in this bank are more likely to be modified
during normal program execution and not just during initialization. Registers in bank 1 are most
likely to be modified only during the initialization phase of the program.
VDD
A name for a power net meaning "voltage drain." The most positive power supply signal. Usually
5 V or 3.3 V.
VSS
A name for a power net meaning "voltage source." The most negative power supply signal.
watchdog timer
A timer that must be serviced periodically. If it is not serviced, the CPU resets after a specified
period of time.
