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.

PACKAGE DIMENSIONS

Notes for Mounting the Surface Mount Type Package

The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which
are very susceptible to heat in reflow mounting and humidity absorbed in storage.
Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the
product name, package name, pin number, package code and desired mounting conditions
(reflow method, temperature and times).
