Description
The M32170 and M32174 Group are 32-bit single chip RISC
microcomputers designed for use in general industrial and
household equipment.
These microcomputers contains a variety of peripheral
functions ranging from16-channel A-D converters to 64chan-
nel multifunction timers, 10-channel DMAs, 6-channel serial
I/Os, 1-channel real time debugger, 1-channel Full-CAN, 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)

64-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 ......................................... 11ch
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 internal RAM independently
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 micro-
computer contains the following peripheral functions.
• DMAC .............................................................. 10 channels
• Two independent
A-D converter .............. (10-bit converter
× 16 channels) × 2
• Serial I/O ............................................................ 6 channels
• Interrupt controller ........... 31 interrupt sources, 8 priority levels
• Wait controller
• Full CAN .............................................................. 1 channel
• JTAG (boundary scan function)
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)
