LIS331EB

MEMS advanced smart sensor: 3D high performance accelerometer and signal processing core
  • active 活性

The LIS331EB is an advanced low-power high-performance smart sensor system which includes a three-axis linear accelerometer and Cortex-M0 core with 64 KB Flash, 128 KB SRAM, 8 dual timers, 2 I2C (master/slave), 1 SPI (master/slave) and 1 UART (transmitter/receiver) in a 3x3x1 mm LGA package. The device features ultra-low-power operational modes that allow advanced power saving and smart sleep-to-wakeup functions. The LIS331EB has user-selectable full scales and 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. One possible use of the LIS331EB is as a sensor hub. For example, the device can collect inputs from the accelerometer (embedded), gyroscopes, compasses, pressure and other sensors through the master I2C and elaborates/fuses together 9 or 10 axes (iNemo Engine software) to provide quaternions to the main application processor. The LIS331EB is ECOPACK®, RoHS and “Green” compliant.
