Overview

1.1

Features

The M16C Family offers a robust platform of 32-/16-bit CISC microcomputers (MCUs) featuring high ROM

code efficiency, extensive EMI/EMS noise immunity, ultra-low power consumption, high-speed processing

in actual applications, and numerous and varied integrated peripherals. Extensive device scalability from

low- to high-end, featuring a single architecture as well as compatible pin assignments and peripheral

functions, provides support for a vast range of application fields.

The R32C/100 Series is a high-end microcontroller series in the M16C Family. With a 4-Gbyte memory

space, it achieves maximum code efficiency and high-speed processing with 32-bit CISC architecture,

multiplier, multiply-accumulate unit, and floating point unit. The selection from the broadest choice of on-

minimize external components.

The R32C/100 Series, in particular, provides the R32C/121 Group, a product specific to vehicle network.

This product, provided as 100-pin plastic molded LQFP package, configures two channels of CAN, two

channels of LIN, and standard peripherals.
