Dual-Core Gyroscope Handles Smart User Interface and Image Stabilization in Phones, Tablets

STMicroelectronics has introduced a dual-core gyroscope capable of handling both user-motion recognition and camera image stabilization. The dual-core gyroscope’s design employs separate output paths optimized for the two different functions in a 4 mm x 4 mm x1 mm package. The device addresses, at the same time, motion and gesture recognition and optical image stabilization for sharper mobile-camera photos. 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 V to 3.6V.
