Accelerometer consumes 90% less power than competitors claims ST
STMicroelectronics has announced a 3-axis digital-output accelerometer that incorporates reduced power consumption – more than 90% lower than available solutions on the market, according to the MEMS supplier.
With operating current consumption as low as 2 microamps, the 3x3x1mm LIS3DH accelerometer is said to be suitable for motion-sensing features and applications in space and power constrained consumer devices, such as mobile phones, remotes and game controllers.
The accelerometer contains a temperature sensor and three analogue to digital converter channels for integration with companion chips, such as gyroscopes. It embeds features including click and double-click recognition, 4D/6D orientation detection, and the power-saving sleep-to-wake-up mode. In this mode, the device keeps the read chain active and wakes up when an event occurs, automatically increasing the output data rate.
Volume production is scheduled for early Q3 2010.
