Verdens første MEMS gyropskop med to 'kerner'

STMicroelectronics lancerer dual-core gyroskop, der kan udføre såvel bevægelsesgenkendelse som billedstablisering (in english)

STMicroelectronics (ST) has introduced the market’s first dual-core gyroscope capable of handling both user-motion recognition and camera image stabilization. With the innovative system architecture of the ST device, equipment manufacturers only need to use a single gyroscope for the two different functions, reducing the size, system complexity, and cost in mobile phones, tablets, and other smart consumer devices.

The innovative design of ST’s dual-core gyroscope employs separate output paths optimized for the two different functions in a 4x4x1 mm package. The device addresses, at the same time, motion and gesture recognition and optical image stabilization for sharper mobile-camera photos.


- ST’s dual-core gyroscope lights two candles with one flame, says Benedetto Vigna, Corporate Vice President and General Manager of ST’s Analog, MEMS and Sensors Group.

- Instead of using two dedicated sensors with significantly different specifications, phone and tablet manufacturers can now simply integrate a single gyroscope for both gesture recognition and camera image stabilization, which enables more reliable performance, sleeker form factors, and lower costs.

Addressing power constraints in battery-operated portable devices, ST’s new gyroscope includes power-down and sleep modes and an embedded FIFO (first-in first-out) memory block for smarter power management. The sensor outputs data through independent I2C and SPI interfaces and offers additional digital embedded features, such as configurable low- and high-pass filters. The gyroscope embeds a temperature sensor and can operate with any supply voltage over the range of 2.4 to 3.6V.

ST’s L3G4IS dual-core gyroscope is sampling now and volume production is scheduled for Q2 2012.
