±4g, ±12g Three Axis Low-g
Micromachined Accelerometer
accelerometer featuring signal conditioning, a 1-pole low pass filter,
temperature compensation, self test, and g-Select which allows for the
selection between 2 sensitivities. Zero-g offset and sensitivity are factory set
and require no external devices. The MMA7331L includes a Sleep Mode that
makes it ideal for handheld battery powered electronics.

... The Freescale accelerometer is a surface-micromachined integrated-circuit accelerometer. The device consists of a surface micromachined capacitive sensing cell (g-cell) and a signal conditioning ASIC contained in a single package. The sensing element is sealed hermetically at the wafer level using a bulk micromachined cap wafer. The g-cell is a mechanical structure formed from semiconductor materials (polysilicon) using semiconductor processes (masking and etching) ...
