GENERAL DESCRIPTION
The OKI MSM80C48/MSM80C49/MSM80C50 are 8-bit, low-power, high-performance micro-
controllers 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.
Available in 40-pin plastic DIP (RS) or 44-pin plastic flat packages QFP (GSK).
