Overview
Description
The R8C/22 Group is supported only for customers who have already adopted these products. The RL78/F12, F13, F14, F15 Groups are recommended for new designs.
This MCU is built using the high-performance silicon gate CMOS process using the R8C CPU core and is packaged in a 48-pin plastic molded LQFP. This MCU operates using sophisticated instructions featuring a high level of instruction efficiency. With 1Mb of address space, it is capable of executing instructions at high speed. This Furthermore, the data flash (1KB x 2 blocks) is embedded in the R8C/21 Group. The difference between R8C/20 and R8C/21 Groups is only the existence of the data flash. Their peripheral functions are the same.
