Description

The W5230 is a CMOS IC that is used solely for the purpose of demonstrating W523X series Low Voltage PowerSpeech products.

The W5230 employs the same JUMP-GO architecture as Winbond's other PowerSpeech products. Unlike standard products, however, the W5230 does not include built-in memory, because the chip is designed to serve only as a demonstration chip for the W523X series ICs. Hence the W5230 must be operated with an external memory device (e.g., an OTP memory). The W5230's LOAD and JUMP commands and four programmable registers provide powerful user-programmable functions that make this chip suitable for a wide range of speech IC applications.
