Mitsubishi Microcomputers

32176 Group

Under Development

Description

32176 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, 4-channel serial I/Os, and 1-channel

real-time debugger. Also included 2-channel Full-CAN mod-

ules and JTAG (boundary scan facility).

With lower power consumption and low noise characteris

tics also considered, these microcomputers are ideal for em-

bedded equipment applications.

SINGLE-CHIP 32-BIT CMOS MICROCOMPUTER

37-channel multijunction timers (MJT)

Multifunction timers are incorporated that support various

purposes of use.

16-bit output related timers ........................... 11 channels

16-bit input/output related timers .................. 10 channels

16-bit input related timers ............................... 8 channels

32-bit input related timers ............................... 8 channels

鈥?Flexible configuration is possible through interconnection

of timers.

鈥?The internal DMAC and A-D converter can be started by a

timer.

Real-time Debugger

鈥?Includes dedicated clock-synchronized serial I/O that can

read and write the contents of the internal RAM indepen-

dently of the CPU.

鈥?Can look up and update the data table in real time while the

program is running.

鈥?Can generate a dedicated interrupt based on RTD commu-

nication.

Features

M32R RISC CPU core

鈥?Uses the M32R family RISC CPU core (Instruction set

common to all microcomputers in the M32R family)

鈥?Five-stage pipelined processing

鈥?Sixteen 32-bit general-purpose registers

鈥?16-bit/32-bit instructions implemented

鈥?DSP function instructions (sum-of-products calculation us-

ing 56-bit accumulator)

鈥?Built-in flash memory

鈥?Built-in flash programming boot program

鈥?Built-in RAM

鈥?PLL clock generating circuit ........................... Multiply by 4

鈥?Oscillation stop detection function

鈥?Maximum operating frequency of the CPU clock

M32176F4VFP/M32176F3VFP/M32176F2VFP

.......... 32 MHz (when operating at -40擄C to +125擄C)

M32176F4TFP/M32176F3TFP/M32176F2TFP

............ 40 MHz (when operating at -40擄C to +85擄C)

鈥?Single power supply: 5V (+0.5V) or 3.3V (+0.3V)

Abundant internal peripheral functions

In addition to the timers and real-time debugger, the micro-

computer contains the following peripheral functions.

鈥?DMAC ............................................................. 10 channels

鈥?A-D converters (Sample & hold function, Disconnection de-

tector assist function, Injection current bypass circuit)

..................................... 16 channels 10-bit converter

鈥?Serial I/O ........................................................... 4 channels

鈥?Interrupt controller ...... 23 interrupt sources, 8 priority levels

鈥?Wait controller

鈥?Full CAN (CAN Specification 2.0B active) ........ 2 channels

鈥?JTAG (boundary scan function, Mitsubishi original SDI de-

bug function)

鈥?Port input threshold level select function .............. 3 levels

Table 1. Type Name List (32176 Group)

Type Name

M32176F4VFP/M32176F4TFP

M32176F3VFP/M32176F3TFP

M32176F2VFP/M32176F2TFP

Designed to operate at high temperatures

To meet the need for use at high temperatures, the microcom-

puter is designed to be able to operate in the temperature

range of -40 to +125擄C 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擄C.

Note: 鈥?This does not guarantee continuous operation at

125擄C. If you are considering use of the micro-

computer at 125擄C, please consult Mitsubishi.
