IA611 Preliminary Brochure Proprietary and Confidential © Copyright 2018 Knowles IA611 The IA611 is an “always-on” Acoustic Processor featuring Voice Wake and Voice ID keyword detector, a three second buffer, and Knowles’ proven high performance acoustic SiSonicTM MEMS 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 times to market with its unique combination of hardware, software, and firmware. Product Features ▪ High-accuracy Voice Wake and Voice ID keyword recognition to wake-up any system from a trigger phrase ▪ Minimum latency when burst out three-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 ▪ Packaged in SPK 4.00 x 3.00 x 1.30 mm Typical Applications ▪ Smartphones ▪ Wearables ▪ Tablets ▪ Small, portable electronics ▪ Remote controllers ▪ Connected home devices IA611 Acoustic Processor Application Processor Acoustic SiSonic MEMS Wake ASR Command Stage 0 Stage 1 Stage 2 Voice Wake Processing Acoustic Activity Detection
