Datasheet
http://cache.freescale.com/files/sensors/doc/data_sheet/MPL3115A2.pdfNotes
The Xtrinsic MPL3115A2 pressure sensor smart features include digital output, two interrupts for auto-wake, minimum/maximum threshold detection and autonomous data acquisition. MCU usage can be limited since the MPL3115A2 pressure sensor can process sensor data locally, reducing communications required with the host processor.
