Description
This MCU is built using the high-performance silicon gate CMOS process using a R8C/Tiny Series CPUcore 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.
