W5280
ADPCM VOICE SYNTHESIZER
(ROM-less
PowerSpeech)
GENERAL DESCRIPTION
The W5280 is a CMOS IC that is used solely for the purpose of demonstrating W528X series
PowerSpeech
products.
The W5280 employs the same JUMP-GO architecture as most of Winbond's other speech
synthesizers. Unlike standard products, however, the W5280 does not include a built-in memory,
because the chip is designed to serve only as a demonstration chip for the W528X series
PowerSpeech
ICs. The W5280 has an ADPCM synthesizer, an 8-bit D/A converter, and all other
necessary control and timing logic, but it must be operated with an external memory device (OTP). The
W5280's LOAD and JUMP commands and four programmable registers provide powerful user-
programmable functions that make this chip suitable for an extremely wide range of speech IC
applications.
