MPL3115A2
I2C Precision Altimeter, Freescale Semiconductor, RoHS


The MPL3115A2 employs a MEMS pressure sensor with an I 2 C interface to 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 uA 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.

Features:

  • 1.95V to 3.6V Supply Voltage, internally regulated by LDO
  • 1.6V to 3.6V Digital Interface Supply Voltage
  • Fully Compensated internally
  • Direct Reading, Compensated:
    • Pressure: 20-bit measurement (Pascals)
    • Altitude: 20-bit measurement (meters)
    • Temperature: 12-bit measurement (degrees Celsius)
  • Programmable Events
  • Autonomous Data Acquisition
  • Resolution down to 1 ft. / 30 cm
  • 32 Sample FIFO
  • Ability to log data up to 12 days using the FIFO
  • 1 second to 9 hour data acquisition rate
  • I2C digital output interface (operates up to 400 kHz)
