BMI270

Product Introduction

The device is a highly integrated, low power inertial measurement unit (IMU) that combines precise acceleration and angular rate measurement in a compact standard size LGA mold package. It integrates a 16-bit digital, triaxial accelerometer with ±2g/±4g/±8g/±16g range and a 16-bit digital, triaxial gyroscope with ±125dps/±250dps/±500dps/±1000dps/±2000dps range.

Features

• Output data rates (ODR): 25 Hz … 6.4 kHz (gyroscope) and 0.78 Hz … 1.6 kHz (accelerometer)
• Programmable low-pass filter (accelerometer | gyroscope): bandwidth 5.5 | 11 … 740 | 751 Hz
• Wide power supply range: Analog VDD 1.71V … 3.6V and independent VDDIO 1.2V…3.6V
• Low current consumption: typ. 685 µA (in full ODR and aliasing free operation)
• Performance mode for gyroscope to minimize noise level: typ. < 7 mdps /√Hz
• Built-in power management unit (PMU) for advanced power management and low power modes
• Rapid startup time: 2 ms for gyroscope (in fast start mode) and 2 ms for accelerometer
• Freely configurable secondary digital interface
• I²C (Fm+) master interface hub for 1 I2C AUX sensor (e.g. ext. magnetometer, pressure) with data synchronized to IMU
• 10 MHz slave SPI (4-wire, 3-wire) for high speed, calibration free OIS / Dual OIS (SPI) applications with up to 6.4 kHz ODR, control register access and down to 680 µs group delay
• Connectible latency optimized low pass-filters with programmable cut-off frequencies
• 2 KB on-chip FIFO buffer for accelerometer, gyroscope, timestamps, and AUX sensor data
• Fast offset error compensation for accelerometer and gyroscope
• Fast sensitivity error compensation for gyroscope (CRT, reducing the error down to typ. 0.4 %)
• HW synchronization of accelerometer, gyroscope, and AUX sensor (< 1 µs)
• Sensortime stamps for accurate system (host) and sensor (IMU) time synchronization (<40 µs)
• 2 independent programmable I/O pins for interrupt and synchronization events
• RoHS compliant, halogen and lead free
