8-Bit Microcontroller with A/D Converter (with LCD Driver)
GENERAL DESCRIPTION
The MSM65354/MSM65353A is a high performance 8-bit microcontroller that employs
OKI original CPU core nX-8/50. The MSM65354 contains 24K-byte program memory, 640-
byte 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.
