FXPS7550D4 Digital absolute pressure sensor, 20 kPa to 550 kPa Rev. 6 28 August 2020 Product data sheet 1 General description The FXPS7550D4 high-performance, high-precision barometric absolute pressure (BAP) sensor consists of a compact capacitive micro-electro-mechanical systems (MEMS) device coupled with a digital integrated circuit (IC) producing a fully calibrated digital output. The sensor is based on NXP s high-precision capacitive pressure cell technology. The architecture benefits from redundant pressure transducers as an expanded quality measure. This sensor delivers highly accurate pressure and temperature readings 2 through either a serial peripheral interface (SPI) or an inter-integrated circuit (I C) interface. The FXPS7550D4 uses either a 3.3 V or 5.0 V power supply. Furthermore, the sensor employs an on-demand digital self-test for the digital IC and the MEMS transducers. The sensor operates over a pressure range of 20 kPa to 550 kPa and over a wide temperature range of 40 C to 130 C. The sensor comes in an industry-leading 4 mm x 4 mm x 1.98 mm, restriction of hazardous substances (RoHS) compliant, high power quad flat no lead (HQFN) 1 2 package suitable for small PCB integration. Its AEC-Q100 compliance, high accuracy, reliable performance, and high media resistivity make it ideal for use in automotive, industrial, and consumer applications. 2 Features and benefits Absolute pressure range: 20 kPa to 550 kPa Operating temperature range: 40 C to 130 C Pressure transducer and digital signal processor (DSP) Digital self-test 2 I C compatible serial interface Slave mode operation Standard mode, fast mode, and fast-mode plus support 32-bit SPI compatible serial interface Sensor data transmission commands 12-bit data for absolute pressure 8-bit data for temperature 2-bit basic status and 2-bit detailed status fields 3, 4, or 8-bit configurable CRC Capacitance to voltage converter with anti-aliasing filter Sigma delta ADC plus sinc filter 800 Hz or 1000 Hz low-pass filter for absolute pressure Lead-free, 16-pin HQFN, 4 mm x 4 mm x 1.98 mm packageNXP Semiconductors FXPS7550D4 Digital absolute pressure sensor, 20 kPa to 550 kPa 3 Applications 3.1 Automotive Engine management digital BAP Small engine control Liquid propane gas (LPG) or compressed natural gas (CNG) engine management 3.2 Industrial Compressed air Manufacturing line control Gas metering Weather stations 3.3 Medical/Consumer Blood pressure monitor Medicine dispensing systems White goods 4 Ordering information Table 1.Ordering information Type number Package Name Description Version FXPS7550DI4 HQFN16 HQFN16, plastic, thermal enhanced quad flat pack no leads 16 terminals 0.8 mm SOT1573-1 pitch 4 mm x 4 mm x 1.98 mm body FXPS7550DS4 4.1 Ordering options Table 2.Ordering options Device Range kPa Packing Interface Temperature range 2 FXPS7550DI4T1 20 kPa to 550 kPa Tape and reel I C -40 C to 130 C FXPS7550DS4T1 20 kPa to 550 kPa Tape and reel SPI 40 C to 130 C FXPS7550D4 All information provided in this document is subject to legal disclaimers.
