Overview
Features
The R8C/38A 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/38A Group have data flash (1 KB × 4 blocks) with the background operation (BGO) function.
