ST's MEMS microphones are designed, developed and manufactured inside ST, creating an industry-unique vertical integrated supply chain. Both analog- and digital-input as well as top and bottom port solutions are available. Our best-in-class acoustic overload point (AOP) and signal-to-noise ratio (SNR) makes ST’s MEMS microphones suitable for applications that require a very high dynamic range, improving audio experience in every environment. Very tight sensitivity matching allows to optimize beamforming and noise cancelling algorithms for multi-microphone arrays. Low power consumption products allow for an extended battery life.

STM32F7 series of very high-performance MCUs with Arm® Cortex®-M7 core:
Taking advantage of ST’s ART Accelerator™ as well as an L1 cache, STM32F7 microcontrollers deliver the maximum theoretical performance of the Cortex-M7 core, regardless if code is executed from embedded Flash or external memory: 1082 CoreMark /462 DMIPS at 216 MHz fCPU.
