Datasheet R8C/LA3A Group, R8C/LA5A Group, R8C/LA6A Group, R8C/LA8A Group R01DS0011EJ0101 Rev.1.01 RENESAS MCU Oct 28, 2011 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. 1.1.1 Applications Household appliances, office equipment, audio equipment, consumer products, etc. R01DS0011EJ0101 Rev.1.01 Page 1 of 102 Oct 28, 2011R8C/LA3A Group, R8C/LA5A Group, R8C/LA6A Group, R8C/LA8A Group 1.
