AMRS-2325
Mobile Navigation Pad Module
Data Sheet
Description
The AMRS-2325 is a navigation pad module for use
with the AMRI-1000 navigation sense and interface IC.
Together they provide a mouse-like pointing solution.
The spring loaded center button has large enough dis-
placement to allow mouse-like cursor control on a variety
of screen sizes. In addition, the center button provides a
click function anywhere in the field of motion with tactile
feedback.
The AMRS-2325 navigation pad module and AMRI-1000
navigation sense and interface IC form a unique naviga-
tion solution for mobile devices by providing superior
tactile feedback as well as multiple cursor control
operating modes in a small package.
Theory of Operation
The AMRS-2325 is a capacitance based sensor module.
A sliding disk is held at a center position by a patented
spring system when the pointer is not being used. Cursor
navigation is activated when slider senses the button
touch.
The sliding disk may be moved in any direction with
excellent tactile feedback provided by the retention
spring system. The navigation sense and interface IC
tracks the movement of the sliding disk on an electrode
array providing a mobile navigation experience similar to
that provided by a PC mouse or analog joystick.
A selection or clicking operation can be performed by
fully pressing the sliding disk. A dome switch provides
tactile feedback for this operation.
