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.

MSM9802/03/05-xxx
Voice Synthesis IC with Built-in Mask ROM
FEDL9802-03-05-05
Issue Date: Nov. 4, 2003
GENERAL DESCRIPTION
The MSM9802/03/05 is a PCM voice synthesis IC with built-in mask ROM.
This IC has two user selectable playback algorithms, OKI Non-linear PCM and straight PCM. It also contains a
current mode 10-bit D/A converter and a low-pass filter.
External control has been made easy by the built-in edit ROM that can form sentences by linking phrases. By
using Oki's Sound Analysis and Editing Tool, ROM data such as Phrase Control Table can be easily set, created,
edited, and evaluated.
With the stand-alone mode/microcontroller interface mode switching pin, the MSM9802/03/05 can support
various applications.
