Voice Synthesis IC with Built-in Mask ROM

GENERAL DESCRIPTION
The MSM9836 is a PCM voice synthesis IC with built-in 3-Mbit mask ROM, D/A converter, and
low-pass filter (LPF).
The MSM9836 is specifically designed for applications that use a microcontroller.
For this reason, functional support for standalone mode and RC oscillation has been omitted
from the MSM9805, and the ROM capacity and the number of phrases have been increased.
By using Oki's Sound Analysis and Editing Tool, ROM data such as Phrase Control Table can be
easily set, created, edited, and evaluated.
The following table lists the functional differences between the MSM9836 and the MSM9805.
