This new device combines Infineon’s expertise in the automotive industry with its technical lead in high-end MEMS microphones to address the need for high performance, low-noise MEMS microphones for automotive applications. The XENSIV IM67D130A is the first microphone in the market to be qualified for automotive applications according to the AEC-Q103 specifications that determine the stress test qualification for sensors in automotive applications. This will help simplify the design-in efforts for the industry and reduce the risk of qualification fails.
The new XENSIV microphone will enable various use cases in harsh automotive environments and can be placed inside or outside of the vehicle. This makes the IM67D130A ideal for in-cabin applications such as hands-free systems, emergency calls, in-cabin communication and to feed all types of sound signals for active noise cancellation (ANC). The microphone is also suited for exterior applications such as siren or road condition detection. These features enable the use of sound as a complementary sensor for advanced driver assistance systems and predictive maintenance.
The high signal-to-noise ratio (SNR) of 67 dB combined with an exceptionally low distortion level leads to optimum speech quality and superior speech intelligence for applications based on speech recognition. Additionally, the microphones have tight sensitivity matching allowing optimized beamforming algorithms for multi-microphone arrays.
The XENSIV MEMS microphone IM67D130A can be ordered now in a PG-LLGA-5-4 package.
