version: Jan. 1998
Previous version: Nov. 1996
GENERAL DESCRIPTION
The MSM65516 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 MSM65516
is capable of high-speed processing, and includes 32K bytes of program memory, 640 bytes of
data memory, timers and serial ports. Also available are the MSM65P516, which replaces the on-
chip program memory with one-time PROM, and the MSM65X516, which uses external
program memory.
