Low-Noise Bottom Port Piezoelectric MEMS Microphone With Wake on Sound Feature Data Sheet VM1010 TM The VM1010 is the worlds first ZeroPower Listening piezoelectric MEMS microphone. It provides an ultra-low power always listening solution, bringing voice activation to battery powered consumer devices. Features: ZeroPower Listening Technology Full audio output upon waking Capable of voice detection with just 18 W operation Extends battery life up to 10x Dust resistant to IP5x The VM1010 is a low-noise single-ended analog MEMS microphone with a Wake on Sound mode that allows detection of voice activity while consuming only 10 A of supply current (or 18 W of power). In this Wake on Sound mode, the microphone detects sounds in the voice band above a configurable acoustic threshold level. When the microphone detects a sound above the threshold, it instantly alerts the system of the acoustic event. The system can then switch the VM1010 to Normal mode with full audio output within 200 Sec. This is fast enough for the VM1010 to capture the sound that exceeds the threshold and send it to the system for processing. This creates the system architecture for ZeroPower Listening. Vesper Technologies Inc - Preliminary Version The VM1010s Wake on Sound mode brings voice activation to battery-powered consumer devices while drawing nearly zero power, making it ideal for voice- interface devices such as smart speakers, TV remotes, smart earbuds, and smart home products. The VM1010 has a small 3.76 mm X 2.95 mm X 1.3 mm package and is reflow solder-compatible with no sensitivity degradation. It operates in environmentally harsh surroundings because it is dust- and moisture-resistant. Specifications All specifications are at 25C, VDD = 1.8 V unless otherwise noted.
