1. Overview
1.1 Features
The R8C/M13B Group of single-chip microcontrollers (MCUs) incorporates the R8C CPU core, which provides
sophisticated instructions for a high level of efficiency. With 1 Mbyte of address space, the CPU core is capable of
executing instructions at high speed. In addition, it features a multiplier for high-speed arithmetic processing.
Power consumption is low, and the supported operating modes allow additional power control. These MCUs are
designed to maximize EMI/EMS performance.
Integration of many peripheral functions on the same chip, including multifunction timer and serial interface,
reduces the number of system components.
The R8C/M13B Group includes data flash (1 KB × 2 blocks).
1.1.1 Applications
Home appliances, office equipment, audio equipment, consumer products, etc.
