SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER
MITSUBISHI
Description
The 32182 Group is a 32-bit, single-chip RISC microcom-
puter with built-in flash memory, which was developed for
use in general industrial and household equipment. To ac-
complish high-precision arithmetic operations, it incorpo-
rates a fully IEEE754 compliant, single-precision FPU.
This microcomputer contains a variety of peripheral func-
tions ranging from 12-channel A-D converters, 37-channel
multijunction timers, 10-channel DMACs, 4-channel serial
I/Os, and 1-channel Real-time Debugger. Also included are
2-channel Full-CAN modules and JTAG (boundary scan
facility). With the software necessary to run these numerous
peripheral functions stored in its large-capacity flash mem-
ory, this microcomputer meets the needs of application sys-
tems for high functionality, high-performance arithmetic
capability, and sophisticated control.
With lower power consumption and low noise characteris-
tics also considered, these microcomputers are ideal for
embedded equipment applications.

37-channel multijunction timers (MJT)
Multijunction timers are incorporated that support various
purposes of use.
16-bit output related timers (TOP) ................... 11 channels
16-bit input/output related timers (TIO)............ 10 channels
16-bit input related timers (TMS) ....................... 8 channels
32-bit input related timers (TML) ....................... 8 channels
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 independ-
ently 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 com-
munication.
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
detector assist function, Injection current bypass circuit)
..................................... 12 channels 10-bit converter
Serial I/O ........................................................... 4 channels
Interrupt controller: 23 interrupt sources, 8 priority levels
Wait controller
Full CAN (CAN Specification 2.0B active) ......... 2 channels
Virtual-Flash emulation function .......... 4K bytes
× 8 banks
JTAG (boundary scan function, Mitsubishi original SDI
debug function)
Port input threshold level select 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 tempera-
ture range of -40 to +125°C when CPU clock operating fre-
quency = 64 MHz. When CPU clock operating frequency =
80 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, and AT),
industrial equipment system control, and high-function OA
equipment (e.g., PPC)
