The IA610 SmartMic is an “always-on” audio processor featuring high-performance keyword recognition, a 43
MHz audio-optimized DSP, and Knowles’ high-performance acoustic SiSonicTM MEMS microphone
technology in a single, miniature, bottom-port microphone package. The solution pushes the system
performance to ultra-low power with its custom core design and optimized instruction set. It accelerates timeto-
market with its highly integrated combination of hardware, software, and firmware.
