SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER
Under Development
Description
37-channel multijunction timers (MJT)
Multifunction timers are incorporated that support various
purposes of use.
32176 Group is a 32-bit, single-chip RISC microcomputer
with built-in flash memory, which was developed for use in
general industrial and household equipment.
16-bit output related timers...........................11 channels
16-bit input/output related timers..................10 channels
16-bit input related timers ............................... 8 channels
32-bit input related timers ............................... 8 channels
• Flexible configuration is possible through interconnection
of timers.
To make full use of microcomputer built-in mass volume
flash memory, this microcomputer contains a variety of pe-
ripheral functions ranging from two independent blocks of
16-channel A-D converters to 37-channel multifunction tim-
ers, 10-channel DMAs, 4-channel serial I/Os, and 1-channel
real-time debugger. Also included 2-channel Full-CAN mod-
ules and JTAG (boundary scan facility).
• The internal DMAC and A-D converter can be started by a
timer.
With lower power consumption and low noise characteris
tics also considered, these microcomputers are ideal for em-
bedded equipment applications.
Real-time Debugger
• Includes dedicated clock-synchronized serial I/O that can
read and write the contents of the internal RAM indepen-
dently of the CPU.
Features
M32R RISC CPU core
• Can look up and update the data table in real time while the
program is running.
• Uses the M32R family RISC CPU core (Instruction set
common to all microcomputers in the M32R family)
• Five-stage pipelined processing
• Can generate a dedicated interrupt based on RTD commu-
nication.
• Sixteen 32-bit general-purpose registers
• 16-bit/32-bit instructions implemented
• DSP function instructions (sum-of-products calculation us-
ing 56-bit accumulator)
Abundant internal peripheral functions
In addition to the timers and real-time debugger, the micro-
computer contains the following peripheral functions.
• DMAC ............................................................. 10 channels
• A-D converters (Sample & hold function, Disconnection de-
tector assist function, Injection current bypass circuit)
..................................... 16 channels 10-bit converter
• Serial I/O ...........................................................4 channels
• Interrupt controller ...... 23 interrupt sources, 8 priority levels
• Wait controller
• Built-in flash memory
• Built-in flash programming boot program
• Built-in RAM
• PLL clock generating circuit........................... Multiply by 4
• Oscillation stop detection function
• Maximum operating frequency of the CPU clock
M32176F4VFP/M32176F3VFP/M32176F2VFP
.......... 32 MHz (when operating at -40°C to +125°C)
M32176F4TFP/M32176F3TFP/M32176F2TFP
............ 40 MHz (when operating at -40°C to +85°C)
• Single power supply: 5V (+0.5V) or 3.3V (+0.3V)
• Full CAN (CAN Specification 2.0B active) ........2 channels
• JTAG (boundary scan function, Mitsubishi original SDI de-
bug function)
• Port input threshold level select function .............. 3 levels

Designed to operate at high temperatures
To meet the need for use at high temperatures, the microcom-
puter is designed to be able to operate in the temperature
range of -40 to +125°C when CPU clock operating frequency =
32 MHz. When CPU clock operating frequency = 40 MHz, the
microcomputer can be used in the temperature range of -40 to
+85°C.

Note: • This does not guarantee continuous operation at
125°C. If you are considering use of the micro-
computer at 125°C, please consult Mitsubishi.
Applications
Automobile equipment control (e.g., Engine, ABS, AT), in-
dustrial equipment system control, and high-function OA
equipment (e.g., PPC)
