Fixed 10-bit resolution

Full resolution, where resolution increases with g range,

up to 13-bit resolution at ±16 g (maintaining 4 mg/LSB

scale factor in all g ranges)

Embedded memory management system with FIFO

technology minimizes host processor load

Single tap/double tap detection

Activity/inactivity monitoring

Free-fall detection

Concurrent four- and six-position orientation detection
