New from austriamicrosystems is the EasyPoint, a joystick module aimed at portable communication devices. It consists of a mechanical stack incorporating a navigation knob with a magnet and the AS5011, a contactless sensing IC. Its simple construction, and the contactless sensing technique implemented by the IC, means that the module offers very high mechanical reliability. The modules support true 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 1,8 mm.
At the core of the EasyPoint joystick module is the AS5011, a magnetic encoder IC that monitors knob displacement relative to its centre position and provides position information via I²C outputs. The IC offers user-selectable power-saving modes and is available in an ultra-thin QFN package (5 x 5 mm, 0,55 mm high).
The joystick modules come in two mechanical versions, either as a complete module with integrated AS5011, or as a mechanical module only. The sizes range from 12,5 x 12,6 mm to 18,6 x 22,6 mm and support 1 mm and 2 mm knob displacement, respectively.
