LIS331EBMEMS advanced smart sensor: 3D high performance accelerometer and signal processing core
The LIS331EB is an advanced low-power high performance smart sensor system in 3x3x1 mm LGA package, including a three-axis linear accelerometer (LIS3DSH) and Cortex-M0 core with 64 KB Flash, 128 KB RAM, RTC, timers, 2 I2C (Master/Slave) and SPI (Master/Slave).
The device features ultra low-power operational modes that allow advanced power saving and smart sleep to wake-up functions.
The LIS331EB has dynamically user selectable full scales and it is capable of measuring accelerations with selectable output data rates up to 1.6 KHz. An embedded self-test capability allows the user to check the functioning of the sensor in the final application. A possible use of the LIS331EB is as a sensor hub.
The device can collect the inputs from accelerometers (embedded), gyroscopes, compasses, and pressure and other sensors through the master I2C and elaborates/fuses together 9 or 10-axes (iNemo Engine software) to provide to the main app processor, for example, with the quaternions.
The LIS331EB is ECOPACK® RoHS and “Green” compliant.
