ML610Q305 and ML610Q306 of CMOS MCUs with speech output function utilizes a proprietary 8bit U8 core to achieve superior performance.In addition, a hardware-based high fidelity speech playback function and high output speaker amplifier make it possible to provide voice functionality on a single chip, improving audio quality, simplifying control, and maximizing MCU performance.ML610Q305 and ML610Q306 adopt the newly developed high fidelity, high compression sound algorithm HQ-ADPCM that provides a clearer sound and richer audio range while reducing data size compared with conventional ADPCM, providing a more comfortable listening experience.This superior playback functionality, combined with a low power high performance U8 core,3V/5V compatible power supply and broad peripheral control functions, provide a single-chip solution for both battery- and AC-driven products.
