Infineon AEC-Q103 Qualified MEMS Microphone for Automotive Applications

Article By : Infineon Technologies AG

Infineon has launched the industry's first AEC-Q103 qualified high-performance XENSIV MEMS microphone for automotive applications.

Infineon Technologies AG have launched the XENSIV IM67D130A, the first MEMS microphone to be qualified for automotive applications, which will help simplify the design-in efforts for the industry and reduce the risk of qualification fails.

The microphone has an increased operating temperature range from -40°C to +105°C to enable various use cases in harsh automotive environments. The high acoustic overload point (AOP) of 130dB SPL allows the microphone to capture distortion-free audio signals in loud environments. Because of that, it can be placed inside or outside of the vehicle.

The IM67D130A is ideal for in-cabin applications such as hands-free systems, emergency calls, in-cabin communication and 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 67dB 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 is fully qualified for the AEC-Q103-003 standard for automotive applications.
