LONDON Analog chip specialist austriamicrosystems (Unterpremstatten, Austria) 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 round 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 degree 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 I2C outputs.
The AS5011 offers user-selectable power-saving modes and is available in an ultra-thin QFN package (5x5mm, 0.55mm high).
"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", says Matjaz Novak, Director of Marketing Industry & 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.
