Description
A2601DC-C is a 3D mouse controller especially designed for USB and PS/2 applications. It can support the USB Standard
Request as well as HID Class Request version 1.1 draft 4. It is compatible with Microsoft/Intel 3D PS/2 mouse. The X/Y axis photo
input with dynamic photo-input resistor and Z axis can support two kinds of scroller input, namely: opto-mechanical and mechanical.
It requires minimal external components to implement 3D USB mouse plus PS/2 mouse. It can be briefly described as an Apexone
ASIC with on-chip USB interface logic. The USB is specified by the Universal Serial Bus Specification V1.1.
