InvenSense Announces World’s First TDM Microphone With an Array of 16 Devices on a Single Bus

SAN JOSE, Calif. & SHANGHAI--(BUSINESS WIRE)--InvenSense, Inc. (NYSE: INVN), a leading provider of MEMS sensor platforms, today announced the world’s first TDM (Time Division Multiplexed) MEMS microphone that can support up to 16 microphones on one bus. With proliferation of connected devices where the main means of communication is far field voice communication, having an array of microphones that can pick up the user’s voice from any direction is key to their success. These microphone arrays allow the device to form a narrow audio band to pick up user’s command in its direction while effectively ignoring noise from every other direction making reliable communication possible. Up to now, device makers had to pick from microphones with interfaces that supported no more than two on a bus leading to complex and expensive solutions for an array of microphones. InvenSense’ ICS-52000 is a low noise microphone that allows a microphone array to connect directly to digital processors without the need for audio converters in the system. All microphones in the array are able to synchronize their acoustic capture enabling precise audio processing.
