High-Performance 3-Axis SmartIndustrial™ MEMS Accelerometer for Industrial Applications

The IIM-42351 is a 3-axis accelerometer packaged in a small 2.5 × 3 × 0.91 mm (14-pin LGA) package.

The IIM-42351 includes multiple capabilities to enable easy, robust and accurate inertial and inclination measurements in Industrial applications, such as low noise, low power, and an output data rate of up to 8 kHz.

The IIM-42351's host interface can be configured to support I3C℠ slave, I²C slave, or SPI slave modes. The I3C℠ interface supports speeds up to 12.5 MHz (data rates up to 12.5 Mbps in SDR mode, 25 Mbps in DDR mode), the I²C interface supports speeds up to 1 MHz, and the SPI interface supports speeds up to 24 MHz.

The device features an operating voltage range from 3.6 V down to 1.71 V.
