Pressure Sensors Transducers Procurement Notes

Verify current availability status as the component may be discontinued or subject to restricted supply conditions. Confirm that the specific T1 suffix matches the required reel packaging configuration. Ensure compatibility with existing PCB footprints for the LGA-8 package. Cross-reference the manufacturer part number against official NXP documentation to avoid counterfeit components. Check for any pending product change notices related to the MEMS acquisition history.

Pressure Sensors Transducers Selection Notes

Select this component when a low-cost, absolute pressure sensor with digital output is required. The 50 kPa to 115 kPa range suits atmospheric pressure monitoring tasks. Consider the LGA-8 package size for tight spatial constraints. Verify that the SPI interface aligns with the host controller's communication capabilities. Ensure the operating temperature range meets the environmental requirements of the target application.

Pressure Sensors Transducers Part Context

The MPL115A1T1 belongs to the MPL115A1 family of miniature SPI digital barometers. Originally developed by Freescale Semiconductor, the product line was transferred to NXP Semiconductors following the acquisition of Freescale's MEMS business. This series is characterized by its small footprint and integration of pressure sensing elements with signal processing circuitry on a single chip.
