Freescale Semiconductor Document Number: MPL3115A2 Data Sheet: Advance Information Rev 2.2, 07/2012 An Energy Efficient Solution by Freescale 2 I C Precision Altimeter MPL3115A2 2 The MPL3115A2 employs a MEMS pressure sensor with an I C interface to 50 to 110 kPa provide accurate Pressure/Altitude and Temperature data. The sensor outputs are digitized by a high resolution 24-bit ADC. Internal processing removes compensation tasks from the host MCU system. Multiple user-programmable, power saving, interrupt and autonomous data acquisition modes are available, including programmed acquisition cycle timing, and poll-only modes. Typical active supply current is 40 A per measurement-second for a stable 30 cm output resolution. Pressure output can be resolved with output in fractions of a Pascal, and Altitude can be resolved in fractions of a meter. The MPL3115A2 is offered in a 5 mm by 3 mm by 1.1 mm LGA package and specified for operation from -40C to 85C. Package is surface mount with a stainless steel lid and is RoHS compliant. Features LGA PACKAGE • 1.95V to 3.6V Supply Voltage, internally regulated by LDO 5.0 mm by 3.0 mm by 1.1 mm • 1.6V to 3.6V Digital Interface Supply Voltage • Fully Compensated internally • Direct Reading, Compensated Top View
