SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER
Description
32171 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.
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, 3-channel serial I/Os, and 1-channel
real time debugger. Also included 1-channel Full-CAN mod-
ules and JTAG (boundary scan facility).
With lower power consumption and low noise characteristics
also considered, these microcomputers are ideal for embed-
ded equipment applications.
Features

• Uses the M32R family RISC CPU core (Instruction set
common to all microcomputers in the M32R family)
• Five-stage pipelined processing
• Sixteen 32-bit general-purpose registers
• 16-bit/32-bit instructions implemented
• DSP function instructions (sum-of-products calculation
using 56-bit accumulator)
• Built-in flash memory
• Built-in flash programming boot program
• Built-in RAM
• PLL clock generating circuit .............. Built-in × 4 PLL circuit

Real-time Debugger
• Includes dedicated clock-synchronized serial I/O that can
read and write the contents of the internalRAM indepen-
dently of the CPU.
• Can look up and update the data table in real time while the
program is running.
• Can generate a dedicated interrupt based on RTD commu-
nication.
Abundant internal peripheral functions
In addition to the timers and real-time debugger, the
microcomputer contains the following peripheral functions.
• DMAC ............................................................ 10 channels
• A-D converter .................... 10-bit converter × 16 channels
• Serial I/O ........................................................... 3 channels
• Interrupt controller ......... 22 interrupt sources, 8 priority levels
• Wait controller
• Full CAN ............................................................ 1 channel
• JTAG (Boundary scan function, Mitsubishi original)
Designed to operate at high temperatures
To meet the need for use at high temperatures, the micro-
computer is designed to be able to operate in the temperature
range of -40 to +125^oC 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^oC.
Note: This does not guarantee continuous operation at
125^oC. If you are considering use of the microcom
puter at 125^oC, please consult Mitsubishi.
Applications
Automobile equipment control (e.g., Engine, ABS, AT), indus-
trial equipment system control, and high-function OA equip-
ment (e.g., PPC)
37-channel multijunction timers (MJT)
Multifunction timers are incorporated that support various
purposes of use.
16-bit output related timers ....................................... 35ch
16-bit input/output related timers .............................. 10ch
16-bit input related timers ........................................... 8ch
32-bit input related timers ........................................... 8ch
• Flexible configuration is possible through interconnection
of timers.
• The internal DMAC and A-D converter can be started by a timer.
