VM3011 Low-Noise PDM Digital Piezoelectric MEMS Microphone with TM Adaptive ZeroPower Listening PRELIMINARY DATASHEET GENERAL DESCRIPTION The VM3011 is a high performance, low noise digital MEMS microphone. It features Vespers Adaptive ZeroPower TM Listening that dramatically extends the battery life of always- on, always listening systems. Adaptive Intelligence constantly monitors the ambient level to activate the system only when a sound is detected above the background noise level. The entire signal chain of always-listening system is in hibernate mode while listening for an event or a wake word. When an event is detected, the microphone switches to a Normal Mode where it will operate as any standard PDM multi-mode microphone. The VM3011 has an industry standard 3.76 x 2.95 x 1.3mm package. The microphone is solder reflow compatible with no sensitivity degradation. Vespers Piezoelectric MEMS construction also enables operation in in environmentally harsh surroundings due to IP57 dust and moisture resistance rating. See Lid Marking Section for actual product marking It is ideal for applications requiring voice activation in battery powered consumer devices.
