• Multiply/accumulator
• On-chip peripherals with individual power-down
PR31100 Processor is a single-chip, low-cost, integrated embedded
processor consisting of MIPS R3000 core and system support logic
to interface with various types of devices.
PR31100 consists of a MIPS R3000 RISC CPU with 4 KBytes of
instruction cache memory and 1 KByte of data cache memory, plus
integrated functions for interfacing to numerous system components
and external I/O modules. The R3000 RISC CPU is also augmented
with a multiply/accumulate module to allow integrated DSP
functions, such as a software modem for high-performance standard
data and fax protocols. PR31100 also contains multiple DMA
channels and a high-performance and flexible Bus Interface Unit
(BIU) for providing an efficient means for transferring data between
external system memory, cache memory, the CPU core, and
external I/O modules. The types of external memory devices
supported include dynamic random access memory (DRAM),
synchronous dynamic random access memory (SDRAM), static
random access memory (SRAM), Flash memory, read-only memory
(ROM), and expansion cards (PCMCIA and/or MagicCard).
PR31100 also contains a System Interface Module (SIM) containing
integrated functions for interfacing to numerous external I/O
modules such as liquid crystal displays (LCDs), the UCB1100 (which
handles most of the analog functions of the system, including sound
and telecom codecs and touchscreen ADC), ISDN/high-speed
serial, infrared, wireless peripherals, Magicbus, etc. Lastly, PR31100
contains support for implementation of power management,
whereby various PR31100 internal modules and external
subsystems can be individually (under software control) powered up
and down.

PIN DESCRIPTIONS
Overview
The PR31100 processor contains 208 pins consisting of input, output, bi–directional, and power and ground pins. These pins are used to
support various functions. The following sections will describe the function of each pin including any special power–down considerations for
each pin.
Pins
The PR31100 PROCESSOR contains 208 total pins, consisting of 136 signal pins, 4 spare pins, 34 power pins, and 34 ground pins. Of the 136
signal pins, 32 of them are multi–function and can be independently programmed either as IO ports or for an alternate standard/normal function.
As an IO port, any of these pins can be programmed as an input or output port, with the capability of generating a separate positive and
negative edge interrupt. See Section 2.3 for a summary of the multi–function IO ports versus their standard functions.

NAME AND FUNCTION
Memory Pins
D(31:0)
I/O
These pins are the data bus for the system. 8–bit SDRAMs should be connected to bits 7:0 and
16–bit SDRAMs and DRAMs should be connected to bits 15:0. All other 16–bit ports should be
connected to bits 31:16. Of course, 32–bit ports should be connected to bits 31:0. These pins are
normally outputs and only become inputs during reads, thus no resistors are required since the
bus will only float for a short period of time during bus turn–around.
A(12:0)
O
These pins are the address bus for the system. The address lines are multiplexed and can be
connected directly to SDRAM and DRAM devices. To generate the full 26–bit address for static
devices, an external latch must be used to latch the signals using the ALE signal. For static
devices, address bits 25:13 are provided by the external latch and address bits 12:0 (directly
connected from PR31100’s address bus) are held afterward by PR31100 processor for the
remainder of the address bus cycle.

slot(s). This signal will assert whenever /CARD2CSH or /CARD2CSL or /CARD1CSH or
/CARD1CSL is asserted and a read transaction is taking place.
105
/CARD2WAIT
I
This pin is the card wait signal from PCMCIA card slot 2.
113
/CARD1WAIT
I
This pin is the card wait signal from PCMCIA card slot 1.
Bus Arbitration Pins
167
/DREQ
I
This pin is used to request external arbitration. If the TESTSIU signal is high and the TESTSIU
function has been enabled, then once /DGRNT is asserted, external logic can initiate reads or
writes to PR31100 processor registers by driving the appropriate input signals. If the TESTSIU
signal is low or the TESTSIU function has not been enabled, then PR31100 memory transactions
are halted and certain memory signals will be tri–stated when /DGRNT is asserted in order to allow
an external master to access memory.
166
/DGRNT
O
This pin is asserted in response to /DREQ to inform the external test logic or bus master that it can
now begin to drive signals.

NAME AND FUNCTION
MBUSINT
I
This pin is the Magicbus interrupt signal. This signal is used to interrupt PR31100 whenever a
peripheral has been attached to or detached from the bus, or whenever a peripheral has initiated
an interrupt event.
88
/CPURES
I
This pin is used to reset the CPU core. This pin should be connected to a switch for initiating a
reset in the event that a software problem might hang the CPU core. The pin should also be pulled
up to VSTANDBY through an external pull–up resistor.
87
/PON
I
This pin serves as the Power On Reset signal for PR31100. This signal must remain low when
VSTANDBY is asserted until VSTANDBY is stable. Once VSTANDBY is asserted, this signal
should never go low unless all power is lost in the system.
Reset Pins
Power Supply Pins
86
ONBUTN
I
This pin is used as the On Button for the system. Asserting this signal will cause PWRCS to set to
indicate to the System Power Supply to turn power on to the system. PWRCS will not assert if the
PWROK signal is low.
82
PWRCS
O
This pin is used as the chip select for the System Power Supply. When the system is off, the
assertion of this signal will cause the System Power Supply to turn VCCDRAM and VCC3 on to
power up the system. The Power Supply will latch SPI commands on the falling edge of PWRCS.
Power Supply Pins (continued)
84
PWROK
I
This pin provides a status from the System Power Supply that there is a good source of power in
the system. This signal typically will be asserted if there is a Battery Charger supplying current or
if the Main Battery is good and the Battery Door is closed. If PWROK is low when the system is
powered off, PWRCS will not assert as a result of the user pressing the ONBUTN or an interrupt
attempting to wake up the system. If the device is on when the PWROK signal goes low, the
software will immediately shut down the system since power is about to be lost. When PWROK
goes low, there must be ample warning so that the software can shut down the system before
power is actually lost.
83
PWRINT
I
This pin is used by the System Power Supply to alert the software that some status has changed
in the System Power Supply and the software should read the status from the System Power
Supply to find out what has changed. These will be low priority events, unlike the PWROK status,
which is a high priority emergency case.
76
VCC3
I
This pin provides the status of the power supply for the ROM, UCB1100, system buffers, and other
transient components in the system. This signal will be asserted by the System Power Supply
when PWRCS is asserted, and will always be turned off when the system is powered down.
41
SIBDIN
I
This pin contains the input data shifted from UCB1100 and/or external codec device.
42
SIBDOUT
O
This pin contains the output data shifted to UCB1100 and/or external codec device.
39
SIBSCLK
O
This pin is the serial clock sent to UCB1100 and/or external codec device. The programmable
SIBSCLK rate is derived by dividing down from SIBMCLK.
40
SIBSYNC
O
This pin is the frame synchronization signal sent to UCB1100 and/or external codec device. This
frame sync is asserted for one clock cycle immediately before each frame starts and all devices
connected to the SIB monitor SIBSYNC to determine when they should transmit or receive data.
44
SIBIRQ
I
This pin is a general purpose input port used for the SIB interrupt source from UCB1100. This
interrupt source can be configured to generate an interrupt on either a positive and/or negative
edge.
37
SIBMCLK
I/O
This pin is the master clock source for the SIB logic. This pin is available for use in one of two
modes. First, SIBMCLK can be configured as a high–rate output master clock source required by
certain external codec devices. In this mode all SIB clocks are synchronously slaved to the main
PR31100 system clock CLK2X. Conversely, SIBMCLK can be configured as an input slave clock
source. In this mode, all SIB clocks are derived from an external SIBMCLK oscillator source,
which is asynchronous with respect to CLK2X. Also, for this mode, SIBMCLK can still be
optionally used as a high–rate master clock source required by certain external codec devices.
67
SPICLK
O
This pin is used to clock data in and out of the SPI slave device.
69
SPIOUT
O
This pin contains the data that is shifted into the SPI slave device.

91
FRAME
O
This pin is the frame synchronization pulse signal between the Video Module and the LCD, and is
used by the LCD to return it’s pointers to the top of the display. The Video Module asserts FRAME
after all the lines of the LCD have been shifted and transferred, producing a full frame of display.
93
DF
O
This pin is the AC signal for the LCD. Since LCD plasma tends to deteriorate whenever subjected
to a DC voltage, the DF signal is used by the LCD to alternate the polarity of the row and column
voltages used to turn the pixels on and off. The DF signal can be configured to toggle on every
frame or can be configured to toggle every programmable number of LOAD signals.
94
LOAD
O
This pin is the line synchronization pulse signal between the Video Module and the LCD, and is
used by the LCD to transfer the contents of it’s horizontal line shift register to the LCD panel for
display. The Video Module asserts LOAD after an entire horizontal line of data has been shifted
into the LCD.

demultiplex the 4–bit data into the desired 8 parallel data lines needed for the LCD.
90
DISPON
O
This pin is the display–on enable signal for the LCD.
74
TESTSIU
I
This pin allows external logic to initiate read or write transactions to PR31100 registers. The
TESTSIU mode is enabled by toggling this signal after the device has powered up. Once the
function is enabled, if the TESTSIU pin is high when the bus is arbitrated (using /DREQ and
/DGRNT), then external logic can initiate read and write transactions to PR31100 registers. This
pin is used for debugging purposes only.
71
TESTCPU
I
This pin allows numerous internal CPU core signals to be brought to external PR31100 pins, in
place of the normal signals assigned to these pins. The CPU core signals assigned to their
respective pins during TESTCPU mode are vendor–dependent. The TESTCPU mode is enabled
by asserting this TESTCPU signal, and this function is provided for generating test vectors for the
CPU core. This pin is used for debugging purposes only.
