MSM65344A Datasheet | OKI Electric

DESCRIPTION The MSM65344A is a high performance 8-bit microcontroller that employs OKI original CPU core n X-8/50. The MSM65344A includes 12K-byte program memory, 384-byte data memory, LCD driver, timer, PWM, serial I/O, and 8-bit A/D converter. Also available is the MSM65P344, which replace the on-chip program memory with one-time PROM. ..
