The IA610 and IA611 (IA61x) are a family of “always-on” SmartMics (microphones) featuring Voice Wake and Voice ID keyword detectors, a 43MHz Tensilica audio-optimized DSP and KNOWLES’ high performance acoustic SiSonicTM MEMS technology in a single, miniature, microphone package. The integrated programmable DSP is made available to 3rd-party algorithms, enabling full customization (IA611). The solution pushes the system performance to ultra-low power with its custom core design and optimized instruction set. It accelerates time-to-market with its complete hardware, software, firmware, code and tools package. The SmartMic family offers the DSP Concepts Audio WEAVER® tool as a complement to the Knowles AuVid design suite.
