SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER
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.

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 +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)
