STMicroelectronics has collaborated with Microsoft Corp. to develop a motion and orientation Human Interface Device (HID) sensor solution for the Windows 8 operating system. ST's MEMS sensors and the sensor-hub solution are now ready to ship in high volumes with the release of Windows 8, said the firm.

ST's sensor hub combines a 3-axis digital gyroscope, a 3-axis digital accelerometer, and a 3-axis digital magnetometer with a proximity sensor, a barometric pressure sensor, and a high-performance STM32 microcontroller that runs ST's iNEMO Engine sensor-fusion algorithms and HID using the Inter-Integrated Circuit (I2C) protocol.

Since 2003, ST has been supplying accelerometers and drivers for Windows for hard-disc-drive data protection to major laptop OEMs. Several major worldwide OEMs and ODMs have selected ST's sensor solutions for their Windows 8-based devices, said the firm.

"The STMicroelectronics sensor-hub solution allows OEMs/ODMs to incorporate sensors into Windows 8-based tablets quickly and achieve a consistent and superior level of performance," said Benedetto Vigna, Executive Vice President and General Manager, Analogue, MEMS and Sensors Group, STMicroelectronics.

Demonstrated through inclusion in Windows 8-based devices, with a standard plug-and-play HID/I2C interface and protocol, ST has significantly reduced the effort necessary to incorporate sensors for OEMs and ODMs. The ST sensor-hub solution is scalable and the BOM costs and board space can be further reduced through the implementation of additional features, including temperature monitoring and battery charging, with the embedded STM32 microcontroller, according to the firm.
