Gyration's new low-cost, fully-integrated mini gyroscope for pointing devices, remote controls and game controllers

The MG1101 is a low-cost, dual-axis miniature rate gyroscope that is fully self-contained for easy integration into human input devices such as computer mice or remote controls. Its unique tri-axial vibratory structure offers high reliability and low manufacturing cost. Internal mounting isolates the vibrating elements, greatly decreasing drift and improving shock resistance. The module can be mounted directly to a printed circuit board, without additional shock mounting.

A unique electromagnetic transducer design and a single etched beam structure utilize the Coriolis effect to sense rotation in two axes simultaneously. The MG1101 includes an integrated analog-to-digital converter (ADC) and communicates via a conventional 2-wire serial interface bus allowing a user or OEM to connect the device directly to a microcontroller with no additional hardware.

The MicroGyro is well suited for low voltage products operating between 2.3 and 3.6 volts. Its low current consumption is enhanced by a low current sleep mode. A temperature sensor is provided for the most demanding applications and a voltage sensor allows simple detection of a low battery condition for battery powered applications. The MG1101 further includes 1K of available EEPROM storage on board.

Suggested applications are human motion tracking, computer pointers, TV remote controllers, game controllers, robotics, factory automation, antenna stabilization and auto navigation.
