Cirrus Logic introduces world's smallest microphone inside the Motorola Moto X. The mem mic (we are calling it the WM1706 due to die marks) measures just 2.5mmx1.6mm. Cirrus Logic did not follow the norm though. This mem microphone integrates the amplifier with the mem sensor in a single 1.24mm x .78mm die. The integration reduces overall component size and minimizes wirebonds (3 as opposed to the norm of 5-8). Expect to find this microphone in other smart phones and wearables in the future.
