MSM9802/03/05-xxx
Voice Synthesis IC with Built-in Mask ROM
This version: Sep. 1999
MSM9802/03/05-xxx
Previous version: May. 1997
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.
