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 at 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 622 Hz in FORCED and CONTINOUS 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
