E2E1015-27-Y4 ¡ Semiconductor MSM65522/65P522 ¡ Semiconductor 8-Bit Microcontroller with A/D Converter ThisMSM65522/65P522 version: Jan. 1998 Previous version: Nov. 1996 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. www.DataSheet4U.com FEATURES : 1 to 10MHz (VDD=4.5 to 5.5V) 1 to 5MHz (VDD=2.7 to 5.5V) : 2.7 to 5.5V : – 40 to +85°C : : : : 8K bytes 384 bytes 400ns @ 10 MHz 81 basic instructions 8/16-bit operation instructions Bit manipulation instructions Compound function instructions • Operating range Operating frequency Operating voltage Operating temperature • Memory space Internal program memory Internal data memory • Minimum instruction execution time • Powerful instruction set • Abundant addressing modes • I/O ports Input only port • Timers • Counters • Serial ports • A/D converter • External interrupts • Interrupt sources • Package Options 42-pin plastic shrink DIP (SDIP42-P-600-1.78) : 8-bit ¥ 3 4-bit ¥ 1 : 8-bit ¥ 1 : 8-bit auto-reload timer ¥ 3 (One timer is shared by the baud rate generator.
