Overview

The R8C/28 Group is supported only for customers who have already adopted these products. The RL78/G14 Group is recommended for new designs.

These MCUs are fabricated using a high-performance silicon gate CMOS process, embedding the R8C CPU core, and are packaged in a 32-pin molded-plastic LQFP. It implements sophisticated instructions for a high level of instruction efficiency. With 1Mb of address space, they are capable of executing instructions at high speed. Furthermore, the R8C/27 Group has on-chip data flash (1KB × 2 blocks). The difference between the R8C/26 Group and R8C/27 Group is only the presence or absence of data flash. Their peripheral functions are the same.
