Overview
Features
The R8C/34W Group, R8C/34X Group, R8C/34Y Group, and R8C/34Z Group of single-chip MCUs incorporate
the R8C CPU core, employing sophisticated instructions for a high level of efficiency. With 1 Mbyte of address
space, and it is capable of executing instructions at high speed. In addition, the CPU core boasts 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, reduces the number of
system components.
The R8C/34W Group and R8C/34X Group have a single channel CAN module and are suitable for LAN systems in
vehicles and for FA.
The R8C/34Y Group and R8C/34Z Group do not have CAN modules.
The R8C/34W Group and R8C/34Y Group have data flash (1 KB × 4 blocks) with the background operation
(BGO) function.
