Austriamicrosystems has announced the AS5013, a contactless magnetic encoder IC which monitors the displacement of a magnet incorporated in a knob relative to its center position, providing x and y position information via an I�C interface. The AS5013 Hall-sensor IC is utilized in the EasyPoint module consisting of a mechanical stack incorporating a navigation knob, a magnet and the AS5013 magnetic encoder IC. Its simple construction and contactless sensing technology give the module high reliability, particularly designed for any kind of 360 degrees navigation input device.

The AS5013 is a complete Hall-sensor IC for human-machine interface applications requiring low power. This chip IC includes user-selectable power-saving modes, five integrated Hall sensing elements for detecting up to ?2 mm lateral displacement, a high-resolution analog-to-digital converter, XY coordinate and motion detection engine and a smart power management controller. The XY co-ordinate registers and magnetic field information which are then transmitted over the I�C interface to the host processor.

Availability: The AS5013 contactless magnetic encoder IC is now available. Meanwhile, the EasyPoint module is available in sizes as small as 8x8x1.5mm.
