STMicroelectronics have announced the LSM6DB0, the latest addition to its iNEMO family. It packs a 3-axis accelerometer, 3-axis gyro and low energy ARM-based Cortex processor in a tiny 3 x 3 mm package.
This chip is designed to interface with baseband chipsets that don't have a sensor co-processor. Additional external sensors can also be hooked up via its I2C interface, allowing the on-board processor to take care of all sensor-related functions to help minimize application latency at a system level. The device is fully compatible with all of the latest mobile operating systems including Android Kit-Kat 4.4. The sensor’s performance is the result of true 6-axis sensing, where both the 3-axis accelerometer and 3-axis gyroscope are manufactured on the same chip. They operate synchronously at the same output data rate,combinig correlated, true six-degree-of-freedom motion and not just separate acceleration and angular-rate inputs.
The accelerometer features a maximum zero-g offset of 100 mg with a typical gyro rate noise of 0.008 dps per square root of Hz at full-scale. Its low power 'always on' aspect allows it to quickly detect orientation and gesture motions while consuming 40% less power than other designs.
