Oki Electric Industry MSM65514
The MSM65514 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 MSM65514 is capable of high-speed processing, and includes 16K bytes of program memory, 384 bytes of data memory, timers and serial ports on chip.GENERAL DESCRIPTION
Also available are the MSM65P514, which replaces the on-chip program memory with one-time PROM, and the MSM65X514, which uses external program memory.FEATURES
