16-bit Microcontrollers with R8C CPU Core (Non Promotion)

The R8C/54x Group is supported only for customers who have already adopted these products. The RL78/F1x Group is recommended for new designs.

The R8C/54E Group, R8C/54F Group, R8C/54G Group, R8C/54H 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 additional power control is possible by selecting the operating mode. The R8C/54E Group, R8C/54F Group, R8C/54G Group, R8C/54H Group are also designed to maximize EMI/EMS performance. Integration of many peripheral functions, including multifunction timer and serial interface on the same chip, reduces the number of system components. The R8C/54E Group and R8C/54F Group incorporate one channel of CAN module, ideal for the LAN systems of automotive and factory automation applications. The R8C/54G Group and R8C/54H Group do not incorporate the CAN module. The R8C/54E Group and R8C/54G Group also have on-chip data flash (1KB × 4 blocks) with background operation (BGO) function.
