Description

The Bosch BMI160 is a MEMS-based inertial measurement unit designed for high-precision motion sensing in space- and power-constrained applications. It provides simultaneous linear acceleration and angular rate measurements with 16-bit digital resolution, enabling accurate orientation tracking and motion analysis.

Engineered for robustness, the sensor operates reliably across an extended industrial temperature range from -40°C to +85°C. Its configurable on-chip interrupt engine allows for autonomous detection of specific motion events like tap, double-tap, orientation change, and any-motion, reducing the need for continuous polling by the host processor and further optimizing system power consumption.

Key Features

High-precision 16-bit digital output for both accelerometer and gyroscope axes
Ultra-low current consumption profile ideal for always-on wearable and mobile devices
Flexible I2C (up to 400 kHz) and SPI (up to 10 MHz) digital communication interfaces
Integrated 1024-byte FIFO buffer stores sensor data to minimize host processor load
Wide operating temperature range ensures reliable performance in harsh environments
Compact 2.0 x 2.0 x 0.98 mm LGA package for minimal PCB footprint
Advanced on-chip features for gesture recognition, step counting, and context awareness
High-value build optimized for performance-to-cost ratio in volume applications

Applications

Augmented Reality (AR) and Virtual Reality (VR) headset orientation tracking
Indoor navigation and pedestrian dead reckoning for smartphones and wearables
Gesture-based control interfaces for consumer electronics and IoT devices
Activity recognition, step counting, and fitness monitoring in smartwatches
Gimbal stabilization and flight control in drones and robotics

Frequently Asked Questions

What is the operating voltage range for the Bosch BMI160 IMU?

The BMI160 has a dual supply architecture. The core sensor (VDD) operates from 1.71V to 3.6V, while the digital I/O pins (VDDIO) can be powered from 1.2V to 3.6V. This allows flexible interfacing with both 3.3V and lower-voltage logic microcontrollers like the ESP32 or nRF52 series.

How do I communicate with the BMI160 sensor?

The BMI160 supports both I2C and SPI digital communication protocols. You can select the interface via a dedicated pin (SPI/I2C select). The I2C address is 0x68 (or 0x69 with SDO pulled high). For SPI, use standard 4-wire mode with maximum clock frequency of 10 MHz.

What is the purpose of the integrated FIFO buffer?

The 1024-byte FIFO buffer stores accelerometer and gyroscope data, allowing the host microcontroller to read data in bursts. This significantly reduces power consumption by letting the MCU sleep between readings and minimizes communication overhead, which is critical for battery-powered always-on applications.

Can the BMI160 detect specific motion gestures autonomously?

Yes. The sensor features a configurable on-chip interrupt engine that can autonomously detect events like tap, double-tap, orientation change, and any-motion/no-motion. When a configured event occurs, an interrupt pin is triggered, waking the host processor only when needed, which optimizes overall system power efficiency.
