Overview
Features
The R8C/38T-A Group of single-chip microcontrollers (MCUs) incorporates 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/38T-
A Group is 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/38T-A Group integrates a touch sensor control unit, which enables detection of the floating capacitance of
the electrostatic capacitive touch electrode.
This group also has on-chip data flash (1 KB × 4 blocks) with background operation (BGO) function.
