Dear customers,
About the change in the name such as "Oki Electric Industry Co. Ltd." and
"OKI" in documents to OKI Semiconductor Co., Ltd.
The semiconductor business of Oki Electric Industry Co., Ltd. was succeeded to OKI
Semiconductor Co., Ltd. on October 1, 2008.
Therefore, please accept that although
the terms and marks of "Oki Electric Industry Co., Ltd.", “Oki Electric”, and "OKI"
remain in the documents, they all have been changed to "OKI Semiconductor Co., Ltd.".
It is a change of the company name, the company trademark, and the logo, etc. , and
NOT a content change in documents.

GENERAL DESCRIPTION
This version: Sep. 1998
MSM64158A/64158AL
Previous version: Mar. 1996
4-Bit Microcontroller with Built-in LCD Driver and Melody Circuit
The MSM64158A (1.5 V)/64158AL (3.0 V) is a high-performance 4-bit microcontroller that
incroporates Oki-original CPU core nX-4/20.
The MSM64158A/64158AL has an LCD driver for up to 144 segments, an event counter, and a
melody circuit. It is best suited for applications such as clocks and LCD games.
