Previous version: Nov. 1996
GENERAL DESCRIPTION
The MSM65512A is a high-performance 8-bit microcontroller that employs OKI original nX-8/
50 CPU core. With a minimum instruction execution time of 400 ns (10MHz clock), the
MSM65512A is capable of high-speed processing, and includes 8K bytes of program memory,
256 bytes of data memory, timers and serial ports. Also available are the MSM65P512A, which
replaces the MSM65512's built-in program memory with one-time PROM, and the MSM65X512A,
which uses external program memory.
