First MIPI standard microphone for IoT and other consumer devices

14-01-2020 | TDK | Test & Measurement

TDK Corporation presents what is claimed to be the world’s first MIPI Standard SoundWire microphone for IoT, mobile and other consumer devices. This multimode microphone pushes the boundaries of digital microphone acoustic performance whilst giving advanced feature sets with very low power.


The T5808 SoundWire microphone features 66dBA SNR and 135dB SPL AOP at 650µA in high-quality mode and decreases power consumption to 215µA in low power mode. The microphone also features concurrent mode, enabling simultaneous audio streams from HQM and LPM that can seamlessly transition back and forth with no audio glitches.


The SoundWire Standards Committee, who conceived the MIPI standard for SoundWire, incorporates technology leaders in application processors, audio DSPs and codecs, and other ICs. SoundWire is a standard audio bus that underpins multiple audio devices including speakers, microphones, codecs and class D amplifiers. The standard transforms how audio devices and ICs communicate by integrating audio and control data for up to 11 devices (e.g. seven mics, four speakers) on a single bus.


“As a member of the SoundWire Standards Committee, Qualcomm Technologies has supported the SoundWire interface on speaker amplifier products for a number of years. We are excited to see TDK’s microphone technology now incorporating this interface,” says Rahul Shinkre, director, Product Management at Qualcomm Technologies, Inc.
