1. Overview
1.1 Features
The R8C/LA3A Group, R8C/LA5A Group, R8C/LA6A Group, and R8C/LA8A Group of single-chip MCUs
incorporate the R8C CPU core, which implements a powerful instruction set for a high level of efficiency and
supports a 1 Mbyte address space, allowing execution of instructions at high speed. In addition, the CPU core
integrates a multiplier for high-speed operation 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, including multifunction timer and serial interface, helps reduce the
number of system components.
The R8C/LA3A Group, R8C/LA5A Group, R8C/LA6A Group, and R8C/LA8A Group have data flash (1 KB × 2
blocks).
1.1.1 Applications
Household appliances, office equipment, audio equipment, consumer products, etc.
