Overview

The IIM-42351 is a 3-axis accelerometer packaged in a small 2.5 mm x 3 mm x 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:

• Low noise: 70 μg/√Hz
• Low power: 0.3 mA with all 3-axes delivering full performance
• Output data rate up to 8 kHz
• Highly accurate external clock input to increase ODR accuracy, reduce system level sensitivity error, improve measurement impacts from device to device variation.
• 2K-byte FIFO that can lower the traffic on the serial bus interface, and reduce power consumption by allowing the system processor to burst read sensor data and then go into a low-power mode
• Wake-on-motion interrupt for low power operation of applications processor
• Operating temperature range: -40°C to 105°C

The host interface can be configured to support I3CSM slave, I2C slave, or SPI slave modes. The I3CSM 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 3.6V down to 1.71V.
