The IA611 SmartMic is an “always-on” Audio Processor featuring Voice Wake and Voice ID keyword detector, a two-second buffer1, and Knowles’ proven high performance acoustic SiSonicTM MEMS microphone technology in a single, 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 3rd party algorithms, enabling unlimited creativity. The solution pushes the system performance to ultra-low power with its custom core design, and accelerates time to market with its highly integrated combination of hardware, software, and firmware.
