1 Basic Description
The BMP585 is an absolute barometric pressure sensor. Its small dimensions, its low power consumption and the high-end 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: < 0.1 PaRMS natively (without low-pass filter enabled)
1.3 μA at 1 Hz in low power mode
Absolute pressure accuracy: ± 30 Pa (typ)
Relative pressure accuracy: ± 6 Pa (typ) per 10 kPa step
Pressure Temperature-induced offset: ± 0.5 Pa/K (typ)
BMP585 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), 12.5 MHz I3C and up to 1 MHz I²C (Fm+)
Output data rates:
o up to 622 Hz in FORCED mode
o up to 480 Hz in CONTINOUS mode
o 0.125…240 Hz in NORMAL mode
Wide power supply range: VDD 1.71...3.6 V and VDDIO 1.08...3.6 V, both independent
Programmable low-pass filter
On-chip FIFO buffer for up to 32 pressure samples
Programmable interrupts, including pressure-changed detection
6 bytes user programmable non-volatile memory
Compact 8-pin metal-lid LGA package with a footprint of typ. 3.25 × 3.25 mm2 and max. 1.96 mm package height.
RoHS compliant, halogen and lead free
Media-robustness
o No impact on performance and reliability by storage at 15 bar
o No failure upon exposure to common household chemicals (chlorine bleach, acetic acid, acetone, oleic acid, and insect repellent)
o Robustness of package to a combination of environmental stress factors (such as heat, moisture and mechanical forces)
o Proposal for Second Level design available to facilitate customers the system integration procedure
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, including water sports
Emergency caller location
Weather forecast
Vertical velocity indication (e.g., rise/sink speed)
Altitude control of drones and flying toys
