Overview
Features
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 1
Mbyte 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 (1 KB × 4 blocks) with background
operation (BGO) function.
