Overview
Features
The R8C/34U Group, R8C/34K Group of single-chip MCUs incorporates 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/34U Group, R8C/34K Group has data flash (1 KB × 4 blocks) with the background operation (BGO)
function.
