The PL-2555, an USB 2.0 docking IC, is consisted of four types of most commonly used peripheral interfaces, namely ATAPI (IDE), Parallel, Serial, and PS/2 interfaces. It is intended to provide an off-the-shelf single chip solution for portable equipments, such as notebook, to extend the peripheral capability via the USB2.0 bus with 480Mbps transfer rate. An USB 2.0 hub is embedded to achieve the most cost-effect goal for multi-peripheral solution. |
