Overview
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-
chip peripheral devices — UART, CRC, DMAC, A/D and D/A converters, timers, I
2
C, and watchdog timer
enables to 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, has two channels of CAN module, two
channels of LIN module, and standard peripherals.
