Now sampling: joystick module for portables

Analog chip specialist austriamicrosystems is signaling a diversification and starting to sample a joystick module based on contactless sensing aimed at portable communication devices.

Dubbed EasyPoint, the device is based on the company's two-dimensional magnetic encoder IC, the AS5011. EasyPoint integrates a mechanical stack incorporating a navigation knob with a magnet and the contactless sensing IC.

The joystick modules support 360 range of movement, encompass a "select" function and can be housed in a variety of form factors, with a module height as low as 1.8mm.

The magnetic encoder IC monitors knob displacement relative to its center position and provides position information via I?C outputs.

The AS5011 offers user-selectable power-saving modes and is available in an ultra-thin QFN package (5mm x 5mm x 0.55mm).

"The user can move a cursor at any angle, change the speed at which the cursor moves, or select items and drag them across the screen," said Matjaz Novak, director of marketing industry and medical at austriamicrosystems.

Samples of the demonstration units come in two mechanical versions, either as a complete module with integrated AS5011 IC or as a mechanical module only.

The sizes range from 12.5mm x 12.6mm to 18.6mm x 22.6mm and support 1mm and 2mm knob displacement, respectively.
