The R8C/M12A Group is supported only for customers who have already adopted these products. The RL78/G12, RL78/G11 Groups are recommended for new designs.

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 1Mb 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.
