Tiny Triaxial Accelerometers from Freescale
February 21, 2007
The MMA7360L, MMA7340L, and MMA7330L triaxial accelerometers from Freescale Semiconductor Inc., Austin, TX, are suited for motion sensing in smart mobile devices. The devices feature zero-g detect for freefall protection, customer-selectable ranges (1.5 g/6 g for MMA7360L, 3 g/12 g for MMA7340L, and 4 g/16 g for the MMA7330L), 400 μA current draw, 3 μA draw in sleep mode, 2.2–3. V operation, self-test function, 1 ms power-up response time, and 0.5 enable response time. The devices can detect fall, tilt, motion, position, shock, and vibration for multiple portable applications and functions.
