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.

  • High-accuracy, low-power voice wake and Voice ID keyword recognition to wake up any system from a trigger phrase
  • Onboard buffer enables seamless voice wake operation
  • Ultra-low power “always on” Acoustic Activity Detector (AAD)
  • Beamforming for enhanced sound quality
  • Open Developer Platform with SDK
  • High Performance SiSonic MEMS with ±1 dB matched sensitivity, 65 dB SNR and 135 dB SPL Acoustic Overload Point
  • Application Memory Size: 168KB
  • IA610 available in bottom port SPH 3.50 x 2.65 x 0.98 mm package, and IA611 available in open DSP top port SPK 4 x 3 x 1.2 mm package

  • High-accuracy Voice Wake and Voice ID keyword recognition to wake-up any system from a trigger phrase
  • Minimum latency when burst out two-second audio buffer using SPI
  • Ultra-low-power “always on” Acoustic Activity Detector (AAD) capable waking the embedded DSP
  • Interrupt signal to the host processor when a voice keyword trigger is detected
  • Integrated power tree from a single 1.8 V supply
  • Extra flexibility with I2C/UART interfaces
  • 248 kB RAM, 160 MFLOPS, 43 MHz, 32-bit complex- valued floating-point ALU, low-power open developer platform with SDK
  • High-Performance Acoustic SiSonic MEMS with ±1 dB matched sensitivity, 65.5 dB SNR and 132.5 dB SPL AOP
