MSM65522中文资料冲电线数据手册PDF规格书

GENERAL DESCRIPTION

The MSM65522 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 MSM65522 is capable of high-speed processing, and includes 8K bytes of program memory, 384 bytes of data memory (RAM), timers, serial ports and an A/D converter on chip. Also available is the MSM65P522, which replaces the on-chip program memory with one-time PROM.
