Bosch IMU enhanced for consumer applications
The BMI323 is six-axis accelerometer and gyroscope suitable for motion-triggered applications in consumer goods.
The inertial measurement unit (IMU) from Bosch comes as a successor to the BMI160 but with improved accelerometer performance as well as lower power consumption.
The BMI323 has a self-calibrating 16-bit triaxial gyroscope, a 16-bit triaxial accelerometer, and a 16-bit digital temperature sensor housed in a 2.5mm by 3.0mm by 0.83mm 14-pin LGA package that is pin-to-pin compatible with the BMI160 and others.
The BMI323 is the first IMU device announced by Bosch Sensortec to include the I3C interface, in addition to the I2C and SPI interfaces.
In high-performance mode, using both the gyroscope and the accelerometer, the BMI323 has a current consumption of 790µA compared to 925µA on the BMI160, which represents a reduction of nearly 15 percent.
The BMI323 includes Bosch Sensortec’s plug-and-play step counter software, so customers don’t need to spend time developing their own algorithms. Other features include motion detection that can turn subsystems on or off when a device, such as a TV remote control, is put down or picked up, thus reducing overall power consumption.
“The BMI323’s combination of simplicity with an excellent price-performance ratio will open up new applications for IMUs,” said Stefan Finkbeiner, CEO at Bosch Sensortec, in a statement. “These will include standard consumer products, such as toys, gaming controllers, remote controls, wearables, fitness trackers, smartwatches as well as tablets and laptops.”
The BMI323 is available now.
