TDK InvenSense IIM-42351 series 3-axis SmartIndustrial™

The IIM-42351 is a 3-axis accelerometer packaged in a small 2.5mm x 3mm x 0.91mm (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: 70μg/√Hz
• Low power: 0.3mA with all 3 axes delivering full performance
• Output data rate up to 8kHz
• 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 12.5MHz (data rates up to 12.5Mbps in SDR mode, 25Mbps in DDR mode), the I²C interface supports speeds up to 1MHz, and the SPI interface supports speeds up to 24MHz.The device features an operating voltage range from 3.6V down to 1.71V
