This highly integrated MCU has the performance of an ARM Cortex-M7 core and flash capacity to manage high-end cloud-based voice UI functionality, including fast wake word detection, advanced audio front end (AFE), and full connectivity stack on a cost- effective LQFP 100-pin package, without additional peripheral or memory requirements.
The qualified software for Amazon AVS for AWS IoT is fully functional and free of charge, except for the evaluation version of the Alexa wake word component, which requires Amazon licensing in a final product.
The ultra-compact, low-power, omnidirectional, digital MEMS microphone consists of a capacitive sensing element and an IC interface with stereo operation capability. The device has a very high AOP in performance mode, a sensitivity range of ±1 dB and a high SNR for all operating modes
This high efficiency 45 W single bridge class-D amplifier with I2S input includes a high-performance D/A converter with performance output MOSFET.
- Highly integrated Amazon-qualified AVS for AWS IoT reference design
- Amazon-qualified acoustic far-field and noisy environment support
- A two microphone-mems-based advanced audio front end with mics spacing down to 25 mm
- Maximum integration and cost-effectiveness with <$10 POS BOM in volume
