MEMS accelerometer for wake-up, context sensing in IoT, wearables
The LIS2DW12 has a 16-bit output and can be set to prioritize low power consumption or low-noise performance, with five settings in either mode. It can avoid waking the system to check for data and allows single-byte transfers.
The unit draws a current as little as 50nA in standby and 380nA in low-power mode at a data output rate of 1.6Hz. The supply voltage range goes from 3.6V down to 1.62V.
Features that support system-level power savings include a 32-level FIFO, a built-in temperature sensor, and a programmable interrupt for freefall, wake up, activity/inactivity, 6D/4D orientation detection, and tap/double-tap detection.
The package measures 2mm by 2mm by 0.7mm.
Engineering samples of the LIS2DW12 are available with volume production due to begin in 1Q17. Budgetary pricing is from $0.75 for orders of 1000 pieces.
