MSM64P155/64P155L

4-Bit Microcontroller with Built-in LCD Driver and Melody Circuit

GENERAL DESCRIPTION

The MSM64P155 (1.5 V)/64P155L (3.0 V) is a one-time-programmable ROM version product,
which has one-time PROM (OTP) as internal program memory. On the other hand, the
MSM64155 is a mask ROM-version product, which has mask ROM as internal program memory.
Unlike the mask ROM-version MSM64155 which has a P-well CMOS structure, the MSM64P155/
64P155L has been fabricated with the N-well CMOS-structured EPROM process technology.
Therefore, the MSM64P155/64P155L differs from the MSM64155 in the polarity of the power
supply for LCD bias generation and in the external circuit structure.
Unlike the mask ROM-version product, the MSM64P155/64P155L cannot be supplied in the
form of a chip. The MSM64P155/64P155L is an OTP-version product used to evaluate an
application program.
The MSM64P155/64P155L has two operation modes, microcontroller operation mode and
PROM mode. The microcontroller operation mode is used to operate the MSM64P155/64P155L
like a mask ROM-version product and the PROM mode is used to program or read the PROM.

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).
