MMA8653FC
3-Axis, 10-bit
Digital Accelerometer
The MMA8653FC is an intelligent, low-power, three-axis, capacitive micromachined
accelerometer with 10 bits of resolution. This accelerometer is packed with
embedded functions with flexible user-programmable options, configurable to two
interrupt pins. Embedded interrupt functions enable overall power savings, by
relieving the host processor from continuously polling data. There is access to
either low-pass or high-pass filtered data, which minimizes the data analysis
required for jolt detection and faster transitions. The device can be configured to
generate inertial wake-up interrupt signals from any combination of the
configurable embedded functions, enabling the MMA8653FC to monitor inertial
events while remaining in a low-power mode during periods of inactivity. The
MMA8653FC is available in a small 10-pin DFN package (2 mm x 2 mm x 1 mm).
