LIS2DW12TR

LIS2DW12TR is an STMicroelectronics femto 3-axis MEMS accelerometer in an LGA-12 package (2 x 2 x 0.7 mm), tape and reel, with user-selectable full scales of +/-2 to +/-16 g, output data rates from 1.6 Hz to 1600 Hz and a 16-bit output over I2C and SPI. Its low-power mode draws 0.38 uA at 1.6 Hz (1 noise mode) and high-performance mode runs at 90 uA, with embedded functions for tap, activity/inactivity, orientation, free-fall and 6D/4D detection plus a 32-level FIFO. Selection advice: pick the LIS2DW12 for battery wearables and asset trackers where the always-on current budget is the constraint; note the FIFO is 32 levels here, not the deeper buffers of the LIS2DH12 generation. The ST eStore lists this code as Active. Parameters verified against ST documentation (DS11811).
