ML22Q54 - 2-Channel Mixing Oki ADPCM Algorithm-Based Speech Synthesis LSI

Datasheet Summary

Description

The ML2250 family is a 2-channel mixing speech synthesis device with an on-chip voice data (i.e., phrases) storing mask ROM and a flash memory.

Besides playing the built-in voice data, this device can output voice data that is input from outside the device.

OKI Semiconductor ML2252/54-XXX, ML22Q54 2-Channel Mixing Oki ADPCM Algorithm-Based Speech Synthesis LSI FEDL2250DIGEST-01 Issue Date: Oct. 15, 2002 This document contains minimum specifications. For full specifications, please contact your nearest Oki office or representative. www.DataSheet4U.com GENERAL DESCRIPTION The ML2250 family is a 2-channel mixing speech synthesis device with an on-chip voice data (i.e., phrases) storing mask ROM and a flash memory. Besides playing the built-in voice data, this device can output voice data that is input from outside the device. This ML2250 family allows to select the playback method from the 8-bit PCM, non-linear 8-bit PCM, 16-bit PCM, 2-bit ADPCM2, and 4-bit ADPCM2 algorithms. And the sound volume is adjustable as well.
