GENERAL DESCRIPTION
The OKI MSM80C48/MSM80C49/MSM80C50 are 8-bit, low-power, high-performance microcontrollers implemented in silicon-gate complementary 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. Eleven new instructions have been added to the NMOS version's instruction set, thereby optimizing power down, port data transfer, decrement and port float functions.
