ML22P808/ML22P804/ML22P802

OKI ADPCM Algorithm-Based Speech Synthesis LSI

This document contains minimum specifications. For full specifications, please contact your nearest OKI office

or representative.

GENERAL DESCRIPTION

The ML22808/ML22804/ML22802-xxx are speech synthesis LSI devices that have P2ROM for storing voice

data. The voice output component has an ADPCM2 decoder to enable high speech quality, a D/A converter,

and a low-pass filter.

It is easy to configure a speech synthesizer by connecting a power amplifier and a CPU externally.

The ML22808/ML22804/ML22802-xxx allow selection of a playback method from among the 8-bit PCM,

non-linear 8-bit PCM, 16-bit PCM, and 4-bit ADPCM2 algorithms and enable volume control.

The ML22808/ML22804/ML22802-xxx, supported by the ROM codes, are the products in which written speech

data is included.

The ML22P808/ML22P804/ML22P802 are OTP products in which speech data can be easily written by the user

using a dedicated writer. These devices are suitable for applications in developing products, manufacturing of a

wide variety of products in small quantities, and requiring quick turn around.
