Shenzhen Mingjiada Electronics specializes in the long-term supply and recycling of the Bosch BMI323 Inertial Measurement Unit (IMU)—a 6-axis motion sensing solution suitable for wearable devices, game controllers, and smart remote controls
I. Product Overview
The BMI323 is a versatile, low-power 6-axis Inertial Measurement Unit (IMU) introduced by Bosch Sensortec. This device integrates precise acceleration and angular rate (gyroscope) measurement capabilities with intelligent on-chip motion-triggered interrupt features, designed to provide fast and accurate inertial sensing solutions for a wide range of applications.
As an easy-to-use standard IMU, the BMI323 is redefining the way consumer electronics and industrial applications interact through its combination of cost-effectiveness, outstanding performance, and integrated functionality. Shenzhen Mingjiada Electronics Co., Ltd., as a professional electronic component supply chain service provider, has long been supplying and recycling Bosch BMI323 and sensor chips from other brands.
II. Key Features
1. Highly Integrated Six-Axis Sensing
The BMI323 integrates a 16-bit three-axis gyroscope, a 16-bit three-axis accelerometer, and a 16-bit digital temperature sensor into a single chip. The combined design of this six-axis IMU enables it to simultaneously detect linear acceleration and rotational angular velocity, providing comprehensive data support for motion sensing.
2. Ultra-Low Power Consumption
When the gyroscope and accelerometer are used simultaneously in high-performance mode, the BMI323 consumes only 790 µA of current. Compared to the 925 µA of its predecessor, the BMI160, power consumption has been reduced by nearly 15%. This feature makes it particularly suitable for battery-powered portable and wearable devices.
3. Intelligent On-Chip Features
The BMI323 integrates a wealth of embedded features that significantly simplify the development process:
Plug-and-Play Step Counter: Incorporates Bosch’s proven step detection algorithm, eliminating the need for engineers to develop from scratch and enabling direct output of precise step counts
Gesture and Motion Recognition: Supports single-tap, double-tap, and triple-tap detection, as well as stationary/motion detection
Orientation and Plane Detection: Can be used for device screen rotation and attitude determination
Motion-Triggered Interrupts: Intelligent on-chip interrupt functionality automatically wakes up or puts subsystems into sleep mode, further reducing overall power consumption
4. Self-Calibrating Gyroscope
The BMI323 features a self-calibrating 16-bit triaxial gyroscope that uses a stationary CRT (Component Re-Tuning) function to compensate for typical MEMS soldering drift, reducing post-soldering sensitivity error to ±0.7%.
5. Advanced Digital Interfaces
The BMI323 is the first IMU product from Bosch Sensortec to include a new I3C interface in addition to I2C and SPI interfaces. The I3C interface provides faster data transfer rates while further reducing power consumption and system complexity.
6. Compact Package
The BMI323 is housed in a miniature 2.5 mm × 3.0 mm × 0.83 mm 14-pin LGA package that is pin-compatible with the BMI160 and other products, facilitating product upgrades and replacements for customers.
7. Wide Voltage and Temperature Ranges
Supply voltage VDD: 1.71 V to 3.63 V
I/O voltage (VDDIO): 1.08 V to 3.63 V
Operating temperature range: -40°C to +85°C
III. Key Application Areas
With its low power consumption, high integration, and rich on-chip features, the BMI323 is suitable for a wide range of consumer electronics and industrial applications:
Wearable and audio devices
Smartwatches, smart bracelets, fitness trackers, ear-worn devices, etc. The BMI323’s plug-and-play pedometer and ultra-low-power always-on mode make it an ideal choice for health monitoring and activity tracking.
Smartphones and Tablets
Screen rotation detection, gesture control, motion-based games, etc.
Gaming and Toys
Game controllers, smart remote controls, and head movement tracking for augmented reality (AR) and virtual reality (VR) devices.
Smart IoT Devices
Smart home devices, as well as fall detection and posture sensing for laptops and tablets.
Industrial and Robotics
Industrial vibration monitoring, robotic posture control, and equipment orientation and motion control.
