Tiny 2x2mm packaged 3-axis accelerometers from Freescale for mobile devices

Freescale Semiconductor has packed three-axis MEMS accelerometer in a 2x2 mm ultra-compact package. The pin-compatible Xtrinsic MMA8652FC 12-bit and MMA8653FC 10-bit accelerometers are designed for motion sensing in mobile devices, including smart phones, tablets, digital cameras, portable navigation solutions and health care applications. MMA8652FC and MMA8653FC supports features such as gesture detection, image stability, tap to control, anti-theft, and tumble and freefall detection.

“Built to complement our extensive portfolio of sensing solutions, the Xtrinsic MMA865xFC family of accelerometers delivers the highest performance available of any 2x2 mm package on the market today,” said Seyed Paransun, vice president and general manager of Freescale’s Sensor & Actuator Solutions Division. “Using these sleek new accelerometers, designers can employ new levels of sensor intelligence through embedded algorithms and computation without compromising sensitivity or performance.”

The MMA865xFC accelerometers deliver advanced sensitivity of 1 mg per LSB and feature six user configurable sample rates that can be set over a range of 1.5 to 800 samples per second. The accelerometers incorporate Freescale’s MEMS transducer and an on-chip FIFO (first-in/first-out) memory buffer.

Other Key Features:
Low noise: 156 micro g per root Hertz (independent of resolution)
Interrupt and IIC interface supply: 1.62 to 3.6 V
Supply voltage : 1.95 to 3.6 V
Output data rate: 1.5 to 800 Hz
Low-power mode: 6 micro amps
Two programmable interrupt pins for seven interrupt sources
Orientation (portrait/landscape) detection with hysteresis

The Xtrinsic MMA8652FC 12-bit accelerometer and MMA8653FC 10-bit accelerometer are now available in sample quantities. Production quantities are planned for Q4 2012 from Freescale and its distribution partners at a suggested resale price of $0.77 (USD) for the MMA8652FC accelerometer and $0.66 (USD) for the MMA8653FC accelerometer in 10,000-piece quantities.
