1. Overview
1.1 Features
The R8C/2C Group and R8C/2D Group of single-chip MCUs incorporates the R8C/Tiny Series CPU core,
employing sophisticated instructions for a high level of efficiency. With 1 Mbyte of address space, and it is capable
of executing instructions at high speed. In addition, the CPU core boasts a multiplier for high-speed operation
processing.
Power consumption is low, and the supported operating modes allow additional power control. These MCUs also
use an anti-noise configuration to reduce emissions of electromagnetic noise and are designed to withstand EMI.
Integration of many peripheral functions, including multifunction timer and serial interface, reduces the number of
system components.
Furthermore, the R8C/2D Group has on-chip data flash (1 KB × 2 blocks).
The difference between the R8C/2C Group and R8C/2D Group is only the presence or absence of data flash. Their
peripheral functions are the same.
1.1.1 Applications
Electronic household appliances, office equipment, audio equipment, consumer equipment, etc.
