Description

The W52900 is a CMOS IC used solely for the purpose of demonstrating the W529xx series PowerSpeech II products.

The W52900 is a 4-bit ADPCM and/or 8-bit PCM ROMless voice synthesizer that provides basic PowerSpeech instructions and a number of more powerful commands, including basic ALU operations, data move, branch, and random number generation. When used with a Winbond OTP or flash EPROM, the W52900 allows users to create demonstration devices quickly and easily.
