This MCU is built using the high-performance silicon gate CMOS process using a R8C/Tiny Series CPU core and is packaged in a 20-pin plastic molded LSSOP. This MCU operates using sophisticated instructions featuring a high level of instruction efficiency. With 1 Mbyte of address space, it is capable of executing instructions at high speed. Furthermore, the data flash ROM (1KB × 2blocks) is embedded in the R8C/15 group.
The difference between R8C/14 and R8C/15 groups is only the existence of the data flash ROM. Their peripheral functions are the same.

Electric household appliance, office equipment, housing equipment (sensor, security), general industrial equipment, audio, etc.
