PL-2555
Hi-Speed USB Docking Controller
OVERVIEW
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.
To take advantage of Plug-and-Play, all the peripheral interfaces, except the serial interface, are
implemented according to the related USB class specifications: a USB mass storage class for ATAPI devices;
a USB printer class for printers; a USB HID device for keyboard and mouse. Since the default drivers are
embedded within most of current OS, no extra driver is needed.
It is possible to configure the parallel controller to implement the ECP/EPP modes to work with parallel
devices other than printers. For some specific applications, the parallel interface can be configured as an
extra ATAPI (IDE) interface.
