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.

MSM6352
Built-in DTMF Generator 4-Bit Microcontroller
This version: Jan. 1998
MSM6352
Previous version: Mar. 1996
GENERAL DESCRIPTION
The MSM6352 is a high-performance 4-bit microcontroller employing complementary metal
oxide semiconductor technology. The use of this device for a repertory telephone, which
employed a conventional microcomputer that was difficult to be configured in a single-chip
device, allows a compact and high-performance telephone set to be monufactured easily.
