BMI055

Overview

The Bosch Sensortec BMI055 is a compact 6-axis Inertial Measurement Unit (IMU) designed for motion detection and rotation measurement. It integrates a digital 3-axis accelerometer with 12-bit resolution and a digital 3-axis gyroscope offering a range of ±2000°/s. The device operates within a supply voltage range of 2.4 V to 3.6 V and supports I2C and SPI interfaces. Housed in a small LGA-16 package measuring 3x4.5 mm, it provides precise data for applications requiring accurate orientation tracking.

Feature Summary

• Integrates 3-axis low-g acceleration sensor and 3-axis gyroscope for 6 degrees of freedom
• Features high-resolution digital output with 12-bit acceleration and 16-bit gyroscope data
• Compact LGA-16 package design suitable for space-constrained mobile devices

Applications

• Smartphone and tablet orientation sensing
• Wearable device motion tracking
• Virtual reality headsets
• Gaming controllers

Procurement Notes

Verify the specific ordering suffix to ensure correct interface configuration and packaging type. Confirm RoHS compliance status as required by project specifications. Check the latest lifecycle status from the manufacturer to ensure availability for new designs. Validate that the selected variant matches the required operating temperature range and voltage specifications for the target application environment.

Selection Notes

Select the BMI055 when a small form factor is critical alongside 6-axis motion sensing capabilities. This component is appropriate for battery-powered devices due to its efficient power consumption profile. Consider this part over higher-axis solutions if magnetic field data is not required. Ensure the host system supports the necessary digital communication protocols for seamless integration into the embedded architecture.

Part Context

The BMI055 belongs to Bosch Sensortec's portfolio of MEMS sensors tailored for mobile electronics. It complements other IMU offerings like the BMI088 but focuses on a smaller footprint and lower cost structure. This series is engineered to meet the stringent size and power requirements of modern consumer electronics while maintaining reliable performance standards.

Replacement Considerations

The BMX055 serves as a direct upgrade path if 9-axis functionality including magnetometer data is needed. For applications requiring higher precision or automotive-grade stability, the BMI088 offers improved noise performance and wider dynamic ranges.
