MSM65344A
8-Bit Microcontroller with A/D Converter (with LCD Driver)
GENERAL DESCRIPTION
The MSM65344A is a high performance 8-bit microcontroller that employs OKI original CPU
core nX-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.
