MSM65354 Datasheet | OKI Electric

DESCRIPTION This MSM65354/65353A version: Jan. 1998 Previous version: Nov. 1996 8-Bit Microcontroller with A/D Converter (with LCD Driver) The MSM65354/MSM65353A is a high performance 8-bit microcontroller that employs OKI original CPU core n X-8/50. The MSM65354 contains 24K-byte program memory, 640byte data memory, LCD driver, A/D converter and shift register. The MSM65353A contains 16K-byte program memory, 384-byte data memory, LCD driver, A/D converter and shift register. Also available is the MSM65P354, which replace the on-chip program memory with .. one-time PROM.
