Expanding its low g inertial sensor consumer product portfolio, Freescale Semiconductor Inc. introduces the MMA6271QT and MMA6281QT highly sensitive dual-axis accelerometers for applications ranging from appliances to cellphones.

These dual-axis accelerometers offer a customer selectable sensitivity within a 2.5g to 10g range (2.5/3.3/6.7/10g), which allows the devices to be used for multiple functions. They detect small changes in force resulting from fall, tilt, motion, position, shock or vibration. These MEMS-based accelerometers are housed in a 16-lead 6-by-6-by-1.45mm QFN Pb-free package.

Key specifications include low-current consumption of 500?A, low-voltage operation at 2.2-3.6V and a fast 1ms power-up response. In sleep mode, the accelerometers draw 3?A for extended battery life. It also feature integrated signal conditioning, amplification and temperature compensation with a low-pass filter. The devices are RoHS compliant.

The MMA6271QT (XY-axis) and MMA6281QT (XZ-axis) are currently available in production quantities. The suggested resale price starts at $4.03 for the MMA6271QT and $4.33 for the MMA6281QT in quantities of 10,000. Suggested consumer product pricing is less than $2 in high volume.
