Knowles' reference design is designed specifically for iot applications and is based on IA611 SmartMic and Trillbit's TrillConnect SDK

     Knowles' IA611 SmartMic always-on audio processor comes with an integrated TrillConnect SDK from Trillbit that uses vibrato to detect wakeup and decode incoming sound data streams, Encoded using Trillbit's Data-over-Sound algorithm, with a sampling rate of 48 kHz (10 ms frame interval), using high-performance acoustic SiSonic MEMS microphone technology, packaged with a miniature top port. IA611 provides flexibility by supporting the most relevant audio and data interfaces.

     Its integrated programmable DSP with 248 KB of RAM, of which 8 KB is available for customer and third party algorithms, enables unlimited creativity. The solution pushes system performance to ultra-low power consumption with a custom kernel design and speeds time to market with a highly integrated hardware, software, and firmware combination.

     Ia611-rdi-01 Xplained Pro Dev kit is a reference design for iot ained Pro, based on IA611 SmartMic and Trillbit's TrillConnect SDK. It supports ultra-low power acoustic vibrato detection, encoding of acoustic data streams, and forwarding of payload data (network credentials) to an embedded processor for network debugging. TrillConnect enables Trillbit's secure one-click connectivity for IoT devices. To quickly prototype SmartMic into iot applications, AI611 has integrated with Microchip SAM D21 Xplained pro MCU board.
