Image of Knowles' IA611 SmartMic Audio Processor and Xplained Pro Development KitKnowles’ IA611 SmartMic always-on audio processor features voice wake and voice ID keyword detector, a two-second buffer, and high-performance acoustic SiSonic™ MEMS microphone technology in a miniature top-port package. The IA611 offers flexibility by supporting the most relevant audio and data interfaces. Its integrated programmable DSP with 248 kBytes of RAM is available for customer and third-party algorithms, enabling unlimited creativity. The solution pushes the system performance to ultra-low-power with a custom core design and accelerates time-to-market with a highly integrated combination of hardware, software, and firmware.

The IA611-RDI-01 Xplained pro development kit is a reference design based on IA611 SmartMic for IoT applications. It enables ultra-low-power acoustic event detection, voice keyword detection, and voice commands to develop a voice UI.  To accelerate prototyping the SmartMic into an IoT application, the AI611 has been integrated with the Microchip SAM D21 Xplained pro MCU board.
