MSM65352/65352B
8-Bit Microcontroller with 4-Bit A/D Converter (with LCD Driver)
GENERAL DESCRIPTION
The MSM65352 is a high performance 8-bit microcontroller that employs OKI original CPU core,
the nX-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.
