Three-axis gyroscope for motion-sensing applications

The LEGD20H gyroscope by STMicroelectronics is designed for advanced motion-sensing applications and is small enough to be used in experimental projects like wearable electronics.

STMicroelectronics’ (NYSE: STM) ST LEGD20H gyroscope, which is designed for advanced motion-sensing applications, measures only 3mm x 3mm and 1mm high. The device enables smaller sensing mechanisms in smart consumer electronics, including mobile phones and tablets, game consoles, digital cameras and industrial tools.

The ultra-small dimensions of this gyroscope also allow experimental projects such as wearable electronics to move closer towards true practicality.

ST’s L3GD20H also helps conserve battery power by drawing 25% lower current than the previous generation of devices. The L3GD20H is also ready for action in only one-fifth of the time after turn on, enabling the end-user application to deliver a better overall experience. Finally, the gyroscope’s output has 60% lower noise, which can help to simplify hardware and software design and speed up communication with the host system leading to faster application performance.

The gyroscope retains a similar register structure as its predecessor (L3GD20),  making it easy for designers to reuse existing software code.
