MP23DB01HPTR

Microphones Overview

The MP23DB01HPTR is an ultracompact, low-power, omnidirectional digital MEMS microphone manufactured by STMicroelectronics. It integrates a capacitive sensing element with an IC interface supporting stereo configuration options. The device features multiple performance modes enabled by varying clock frequencies: power-down, low-power, and high-performance. Key electrical parameters include a sensitivity of -41 dBFS ±1 dB in performance mode and -24 dBFS ±1 dB in low-power mode. It offers a 135 dBSPL acoustic overload point and a signal-to-noise ratio of 65 dB in performance mode. Typical current consumption is 2 µA in sleep mode, 285 µA in low-power mode, and 800 µA in performance mode.

Microphones Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status via official datasheets as regulatory requirements may vary by region. Check manufacturing lifecycle status, as this component has been marked as Not Recommended for New Designs (NRND) or End-of-Life by the manufacturer. Ensure supply chain partners provide valid traceability documentation for quality assurance purposes.

Microphones Selection Notes

Select this component when high acoustic overload point and tight sensitivity matching are critical for array-based processing. It is suitable for applications requiring low power consumption across multiple operating states. Consider the RHLGA package constraints for PCB layout. Verify compatibility with host microcontrollers supporting PDM or I²S interfaces for digital audio data reception.

Microphones Part Context

This part belongs to the MP23DB01HP series of digital MEMS microphones from STMicroelectronics. It is designed to replace older analog microphone solutions in modern digital audio systems. The device is commonly integrated into reference platforms like the STEVAL-MKBOXPRO-Audio and B-U585AI-IOT02A boards for voice recognition and audio processing development.

Microphones Replacement Considerations

The MP23DB02MM is a verified substitute within the same family, offering similar omnidirectional characteristics and package type but with different sensitivity specifications (-26 dBFS). Evaluate pinout compatibility and software configuration adjustments when migrating between these variants.
