A thin input device that combines a navigation pad module with a motion sense and interface chip to provide a mouse-like pointing product for use in various mobile devices is now available from Avago Technologies.

The input device combines the AMRT-1410 navigation pad module and the AMRI-2000 mobile navigation sense and interface IC. The AMRT-1410 incorporates a self-centering snap-on button, which can be customized to meet industrial design requirements. With a low profile height of 1.7mm and diameter of 14mm, the ultracompact navigation pad incorporates a self-centering button with click function.

The AMRI-2000 IC enables the input module to operate either as a four- or eight-way switch with scroll-wheel functionality or as an analog mouse or joystick to provide end-users with navigation features such as rapid scrolling and panning of menus and long lists. Typical applications include mobile phones, ultraminiature PCs, digital still cameras, computer peripheral and other handheld and gaming applications.

Based on embedded capacitive sense technology, the miniature input module will enable designers to develop input devices for mobile devices that can enhance the user's experience by providing analog cursor control for web browsing, gaming or digital camera applications. It sells for $3 per bundle in high volumes.
