The IIS2MDC includes an I²C serial bus interface that supports standard, fast mode, fast mode plus, and high-
speed (100 kHz, 400 kHz, 1 MHz, and 3.4 MHz).
The device can be configured to generate an interrupt signal for magnetic field detection. It can be used as a
slave device with the
ISM330DHCX device configured as a master using the solder bridge configuration.

2.7 Microphone: MP23DB02MM
The MP23DB02MM is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a
capacitive sensing element and an IC interface with optional stereo configuration. The sensing element, capable
of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to
produce audio sensors. It has a narrow sensitivity range of ±1 dB, high SNR, and low distortion for all operative
modes.

Package RHLGA 5LD
Two digital microphones are available on the board to give flexibility for different configurations. Both are mounted
from the bottom with hole on the PCB to input the audio signal.
MP23DB02MM offers multiple performance
modes enabled by different clock frequency ranges (power down, low power, and normal mode).
