The sensor module is housed in an extremely compact 10-pin metal-lid LGA package with a footprint of only 2.0 × 2.0 mm² and max 0.8 mm package height. Its small dimensions and its low power consumption of 3.4 µA @1Hz allow the implementation in battery driven devices such as mobile phones, GPS modules or watches. Typical applications • Vertical velocity indication (e.g. rise/sink speed) • Internet of things • Enhancement of GPS navigation (e.g. time-to-first-fix improvement, dead-reckoning, slope detection) • Indoor navigation & localization (floor detection, elevator detection) • Outdoor navigation, leisure and sports applications • Weather forecast • Health care applications (e.g. spirometry) • Fitness applications like enhancement of calorie detection • AR & VR applications • Context awareness Target Devices • Flying toys • Drones • Handsets such as mobile phones, tablet PCs, GPS devices • Navigation systems • Portable health care devices • Home weather stations • Watches • White goods Modifications reserved |Data subject to change without notice | Printed in Germany Document number: BST-BMP388-DS001-06 Revision_1.6_042020 Bosch Sensortec | BMP388 Datasheet 3 | 59 Key features Package Table 1: Key Features of BMP388 2.0 mm x 2.0 mm x 0.75 mm metal lid LGA Digital interface I²C (up to 3.4 MHz) and SPI (3 and 4 wire, up to 10 MHz) Supply voltage VDD main supply voltage range: 1.65 V to 3.6 V VDDIO interface voltage range: 1.2 V to 3.6 V Relative accuracy typ. ± 8 Pa, equiv. to ± 0.66 m (900 … 1100 hPa, 25 . . . 40 °C ) Absolute accuracy typ. ± 50 Pa (300 ...1100 hPa, -20 ...+65 °C) Temperature coefficient offset typ. ± 0.75 Pa/K (0 ... 55°C @700 -1100 hPa) Current consumption 3.4 µA at 1 Hz pressure and temperature 2.0 µA in sleep mode Operating range -40 ‒ +85 °C, 300‒1250 hPa The product is RoHS compliant, halogen-free, MSL1 BMP388 enables accurate altitude tracking and is specifically suited for drone applications. The best-in-class TCO between -20-65°C for accurate altitude measurement over a wide temperature range of the BMP388 greatly enhance the drone flying experience by making accurate steering easier. It is compatible for use with other Bosch sensors, including the new BMI088 for better performance, robustness and stability. The new BMP388 sensor offers outstanding design flexibility, providing a single package solution that can also be easily integrated into other existing and upcoming devices such as smart homes, industrial products and wearables. The sensor is more accurate than its predecessor BMP280, covering a wide measurement range from 300 hPa to 1250 hPa. This new barometric pressure sensor exhibits an attractive price-performance ratio coupled with low power consumption. It is available in a compact 10-in 2.0 x 2.0 x 0.75 mm³ LGA package with metal lid Due to the built-in hardware synchronization of the pressure sensor data and its ability to synchronize data from external devices such as acceleration sensors, the BMP388 is ideally suited for fitness and navigation applications which require highly accurate, low power and low latency sensor data fusion. The new interrupt functionality provides simple access to data and storage. Examples of interrupts than can be used in a power efficient manner without using software algorithms include: Data ready interrupt, watermark interrupt (on byte level) or FIFO full interrupt. BMP388 also includes a new FIFO functionality. This greatly improves ease of use while helping to reduce power consumption of the overall device system during full operation. The integrated 512 byte FIFO buffer supports low power applications and prevents data loss in non-real-time systems.
