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
MSM65354/65353A
version: Jan. 1998
Previous version: Nov. 1996
8-Bit Microcontroller with A/D Converter (with LCD Driver)
The MSM65354/MSM65353A is a high performance 8-bit microcontroller that employs
OKI original CPU core nX-8/50. The MSM65354 contains 24K-byte program memory, 640-
byte data memory, LCD driver, A/D converter and shift register. The MSM65353A contains
16K-byte program memory, 384-byte data memory, LCD driver, A/D converter and shift
register. Also available is the MSM65P354, which replace the on-chip program memory with
one-time PROM.
