Product Overview: 

AX8 series is a cost-effective voice chip with 20~170 seconds (6K/4bits) model options for simple applications without adding any external components. In addition, the AX8 series can be burned in one time, providing a user-friendly compilation interface that eliminates the need to write program code and simplifies the product development process.
