Overview

The R8C/26 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/Tiny Series CPU core, and are packaged in a 52-pin molded-plastic LQFP or a 64-pin molded-plastic FLGA. 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/25 Group has on-chip data flash (1KB x 2 blocks). The difference between the R8C/24 Group and R8C/25 Group is only the presence or absence of data flash. Their peripheral functions are the same.

  3. What is the differences between the R8C Family and the M16C/60 Series

    The R8C Family doesn't support JMPS and JSRS instructions. These instructions branch to the program set from F0000h to FFFFFh block number, but the R8C Family has no ROM in this area, so you can't use these.
