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

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.

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.
