CST57005 Product Overview:
CST57005 is a new generation of cost-effective voice chips with a 9-bit high-performance PWM voice engine. And it has a diversified model selection of 5 seconds (6K/4 bits), with no need to add any external components for simple applications, giving the overall cost a market leading advantage. In addition, this series can burn program content in one go, providing a user-friendly compilation interface without the need to write program code, simplifying the product development process.
