M80C49 Overview
The OKI MSM80C48/MSM80C49/MSM80C50 are 8-bit, low-power, high-performance microcontrollers implemented in silicon-gate plementary metal-oxide semiconductor technology. Integrated within these chips are 8K/16K/32K bits of mask program ROM, 512/1024/2048 bits of data RAM, 27 I/O lines, built-in 8 bit timer/counter, and oscillator. Program memory and data paths are byte wide.
