R8C/28 Group, R8C/29 Group
SINGLE-CHIP 16-BIT CMOS MCU
1. Overview
These MCUs are fabricated using a high-performance silicon gate CMOS process, embedding the R8C CPU core, and
are packaged in a 20-pin molded-plastic LSSOP. It implements sophisticated instructions for a high level of instruction
efficiency. With 1 Mbyte of address space, they are capable of executing instructions at high speed.
Furthermore, the R8C/29 Group has on-chip data flash (1 KB × 2 blocks).
The difference between the R8C/28 Group and R8C/29 Group is only the presence or absence of data flash. Their
peripheral functions are the same.
1.1 Applications
Electronic household appliances, office equipment, audio equipment, consumer products, automotive, etc.
