GENERAL DESCRIPTION

The IIM-42352 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-42352 includes multiple capabilities to

enable easy, robust and accurate inertial and

vibration measurements in Industrial applications:

• Wide and flat frequency response range:

from dc to 4 kHz (±3 dB point)

• Low noise: 70 µg/√Hz

• Low power: 0.3 mA with all 3-axes

delivering full performance

• Output data rate up to 32 kHz

• Highly accurate external clock input to

increase ODR accuracy, reduce system level

sensitivity error, and 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, I2

C 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 I2

C 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.
