Avago Technologies has developed a thin, compact input device to provide a mouse-like pointing solution for a variety of mobile devices. Based on embedded capacitive sense technology, the device combines the AMRT-1410 ultra-compact 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 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.
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. 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.
With a profile height of 1.7 mm and diameter of 14 mm, the AMRT-1410/AMRI-2000 input device is priced below $3 in high volumes. Samples and production quantities are available now.
