Input Device from Avago provides a mouse-like pointing solution for use in a variety of mobile devices

Avago's latest input device solution combines its AMRT-1410 Ultra-Compact Navigation Pad Module and 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 an integrated click function in an ultra-compact package. The AMRI-2000 IC enables the input module to operate either as a four- or eight-way switch with scrollwheel functionality or as an analog mouse or joystick to provide end-users with new and unique navigation experiences such as rapid scrolling and panning of menus and long lists, mouse-like navigation of web pages, drag and drop operations, as well as analog joystick-like control to make mobile gaming more enjoyable. In addition, with the capacitive sense technology incorporated into this input device solution, bare skin contact is not required for operation of the navigation pad module. As a result, end-users will have the added benefit of being able to operate the input device while wearing gloves.

The operating mode of the AMRT-1410 and AMRI-2000 input device solution can be dynamically reconfigured to provide the best user navigation experience for any active application. Moreover, the backward compatible digital switch mode with scroll function provides the user with a well known interface for menu and list navigation. For example, the navigation pad can function as an analog joystick for a gaming application, as a digital 4-way switch with scrollwheel functionality for menu navigation and phonebook or MP3 list scrolling, and as a mouse for web page navigation and image manipulation.

This latest input device solution from Avago addresses the need in the market for an ultra-compact, small form factor advanced analog input device that can provide joystick or mouse-like cursor navigation with an integrated select button for mobile and handheld devices, says Khin-Mien Chong, vice president and general manager, Mobile Input Device Operations, Avago Technologies. The unique arrangement of this input device solution with its center button supports single handed operation including drag and drop functionality. In addition, the input module provides backward compatible digital rocker switch modes including scrollwheel functionality for ease of first time use.

Avago's AMRT-1410 and AMRI-2000 provides designers with an input module that provides tactile feedback for intuitive use, an integrated tactile click, and a capacitive sensor IC. The IC interfaces to the host over an I2C-compatible or SPI serial bus. Moreover, this IC was designed specifically for low battery power operation and includes programmable auto wake-up power saving modes to conserve power and extend battery life.
