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 μA of supply current (or 18

μW 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 μSec. 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.
