ST cuts size of smartphone gyro chip

The L3G462A is a low-power 3-axis angular rate sensor.

It includes a sensing element and an IC interface able to provide the measured angular rate to the external world through three analog outputs.

The sensing element is manufactured using a dedicated micromachining process developed by ST 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 L3G462A is available in a plastic land grid array (LGA) package and can operate within a temperature range from -40 °C to +85 °C.

Key Features

  • ± 625 dps full scale
  • Wide supply voltage range 2.4 V to 3.6 V
  • Embedded power-down and sleep mode to save power consumption and shorten turn-on time
  • Integrated temperature sensor
  • Embedded low pass filter
  • High shock survivability
  • Extended operating temperature range (-40 °C to 85 °C)
  • ECOPACK® RoHS and “Green” compliant

STMicroelectronics is offering a 3-axis analogue output gyroscope in a small 4x4x1mm3 package.

The L3G462A gyroscope provides angular-rate detection with a separate output for each of the three axes.

The full scale of ±625dps will measure gestures and movements of different types and speeds, enabling applications from navigation to motion-activated user interface and gaming.

Stability over temperature is specified as ±0.04dps/°C and sensitivity at ±0.017%/°C.

Noise is specified  0.017dps/?Hz.

It can operate with any supply voltage in the range of 2.4 to 3.6V and the power-down and sleep-to-wake modes contribute to the reduction in power consumption of the entire system.
