Description

General part information

R8C/38T-A Series

The R8C/38T-A Group of single-chip MCUs incorporates the R8C CPU core, which provides sophisticated instructions for a high level of efficiency.

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 1Mb 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/38TA 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 (1KB × 4 blocks) with background operation (BGO) function.
