IIM-42352 Product Brief
High-performance 3-Axis SmartIndustrial Accelerometer
MEMS Device for Industrial Applications
GENERAL DESCRIPTION
APPLICATIONS
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.

Robotics
The IIM-42352 includes multiple capabilities to
enable easy, robust and accurate inertial and
vibration measurements in Industrial applications:
FEATURES
•
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
•
Digital-output X-, Y-, and Z-axis
accelerometer with programmable full-
scale range of ±2g, ±4g, ±8g and ±16g
User-programmable interrupts
I3CSM / I2C / SPI slave host interface
Digital-output temperature sensor
External clock input supports highly
accurate clock input from 31 kHz to 50 kHz
Small and thin package:
2.5 mm x 3 mm x 0.91 mm (14-pin LGA)
20,000g shock tolerant
MEMS structure hermetically sealed and
bonded at wafer level
RoHS and Green compliant

TYPICAL OPERATING CIRCUIT
AP_CS
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.
