MEMS motion sensor: 3-axis digital gyroscope

The L3GD20 is a low-power three-axis angular rate sensor.

It includes a sensing element and an IC interface capable of providing the measured angular rate to the external world through a digital interface (I2C/SPI).

The sensing element is manufactured using a dedicated micro-machining process developed by STMicroelectronics to produce inertial sensors and actuators on silicon wafers.

The IC interface is manufactured using a CMOS process that allows a high level of integration to design a dedicated circuit which is trimmed to better match the sensing element characteristics. The L3GD20 has a full scale of ±250/±500/ ±2000 dps and is capable of measuring rates with a user-selectable bandwidth.

The L3GD20 is available in a plastic land grid array (LGA) package and can operate within a temperature range of -40 °C to +85 °C.

Key Features

  • Three selectable full scales (250/500/2000 dps)
  • I2 C/SPI digital output interface
  • 16 bit-rate value data output
  • 8-bit temperature data output
  • Two digital output lines (interrupt and data ready)
  • Integrated low- and high-pass filters with user-selectable bandwidth
  • Wide supply voltage: 2.4 V to 3.6 V
  • Low voltage-compatible IOs (1.8 V)
  • Embedded power-down and sleep mode
  • Embedded temperature sensor
  • Embedded FIFO
  • High shock survivability
  • Extended operating temperature range (-40 °C to +85 °C)
  • ECOPACK® RoHS and “Green” compliant
