Description

The W58100 is a CMOS IC that is used solely for the purpose of demonstrating the W581xx series enhanced PowerSpeechä products.

The W58100 employs the same JUMP-GO architecture as Winbond's other PowerSpeechä products. Unlike standard products, however, the W58100 does not include built-in memory, because the chip is designed to serve only as a demonstration chip for the W581xx series ICs. Hence the W58100 must be operated with an external memory device (e.g., a flash EPROM memory IC). The W58100's LOAD and JUMP commands and 8 programmable registers provide powerful user-programmable functions that make this chip suitable for a wide range of speech IC applications.
