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
M32R RISC CPU core
• 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
• Maximum operating frequency of the CPU clock
40MHz(when operating at -40 to +85oC)
32MHz(when operating at -40 to +125oC)

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.
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 +125oC 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 +85oC.
Note: This does not guarantee continuous operation at
125oC. If you are considering use of the microcom
puter at 125oC, 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)
