MSM65352B Datasheet | OKI Electric

DESCRIPTION This MSM65352/65352B version: Jan. 1998 Previous version: Nov. 1996 8-Bit Microcontroller with 4-Bit A/D Converter (with LCD Driver) The MSM65352 is a high performance 8-bit microcontroller that employs OKI original CPU core, the n X-8/50. The MSM65352 includes 8K-byte program memory, 256-byte data memory, LCD driver, timer, serial I/O and 4-bit A/D converter. Also available is the MSM65352B, which has four LCD outputs in place of four output ports. Also available are the MSM65P352 and MSM65P352B, which replace the on-chip program memory with one-time PROM. ..
