Overview

The R8C/M13B Group is supported only for customers who have already adopted these products. The RL78/G1F, RL78/G1G Groups are recommended for new designs.

The R8C/M11A Group and R8C/M12A Group of single-chip microcontrollers (MCUs) incorporate the R8C CPU core, which provides sophisticated instructions for a high level of efficiency. With 1Mb 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/M11A Group and R8C/M12A Group include data flash (1KB × 2 blocks).
