1 Basic Description

The BMP581 is an absolute barometric pressure sensor. Its small dimensions, its low power consumption and the

highend performance allow the implementation in a wide range of applications.

Key features:

Pressure operating range: 30 .. 125 kPa

Temperature operating range: -40 .. 85°C

Ultra low noise and current consumption:



Ultra low noise: < 0.1PaRMS natively (without low-pass filter enabled)



1.3 µA 1Hz in low power mode

Absolute pressure accuracy: ± 0.5 hPa (max)

Relative pressure accuracy: 0.06 hPa per 10kPa step

Pressure Temperature-induced offset: ± 0.5 Pa/K

BMP581 provides true absolute pressure and temperature, due to on-chip linearization and temperature-

compensation

Primary digital interface with 12 MHz slave SPI (4-wire, 3-wire), 12.5MHz I3C and up to 1MHz I²C (Fm+)

Output data rates:



up to 480 Hz in CONTINUOUS mode



0.125 .. 240 Hz in NORMAL mode

Wide power supply range: VDD 1.71 V ... 3.6 V and VDDIO 1.08 V ... 3.6 V, both independent

Programmable low-pass filtering

On-chip FIFO buffer for up to 32 pressure samples

Programmable interrupts, including pressure-changed detection

6 bytes user programmable non-volatile memory

Compact 10-pin metal-lid LGA package with a footprint of only 2.0 × 2.0 mm2 and max 0.8 mm package height.

RoHS compliant, halogen and lead free

Typical applications:

Enhancement of GPS navigation (e.g. time-to-first-fix improvement, dead-reckoning, slope detection)

Indoor navigation (floor detection, elevator detection)

Outdoor navigation

Sports applications like calorie counting, fitness activity identification

Emergency caller location

Weather forecast

Vertical velocity indication (e.g. rise/sink speed)

Altitude control of drones and flying toys

Target devices:

Handsets such as mobile phones, tablet PCs, GPS devices

Navigation systems

Portable health care devices

Home weather stations

Drones and flying toys

Smart watches

Virtual and augmented reality devices
