MSM6353/6353L-xx
Built-in 8 or 5 bit Serial Port 4-Bit Microcontroller
GENERAL DESCRIPTION
The MSM6353/6353L is a low-power 4-bit microcontroller manufactured in CMOS process
technology. It is best suited for the control of battery-driven equipment. The built-in 8-bit or
5-bit serial port provides a data communication capability with external apparatus.
FEATURES

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).
