Design Applications
Add Hi-Speed USB 2.0 to a Printer
The NET2280 can be used to easily add Hi-Speed USB 2.0
functionality to any PCI-based printer. The standard PCI
interface of the NET2280 connects gluelessly to a printer’s
PCI bus backplane. Standard PCI registers allow the printer’s
CPU to easily configure and send data to and from the
NET2280.
The NET2280 features six programmable USB endpoints for
any combination of Interrupt, Isochronous, and Bulk data
transfers. This allows printer applications to transfer different
data (such as diagnostic or critical print data) through different
endpoints to improve quality of service and ease of design.
PLX provides device firmware to configure the NET2280 to
resemble a standard USB Printer Class device. With the USB
Printer Class firmware, these devices can be recognized by
PCs without any additional host-side drivers.
In these applications, the integrated CPU is usually not
needed.

Migrate PCI and CardBus Designs to USB
The NET2280 is designed to easily convert existing PCI Cards
or CardBus Adapters to stand alone USB Devices. Since both
PCI and CardBus chips are based around the standard PCI
protocol, the NET2280 connects gluelessly with them.
Instead of a PCI Host Chipset and BIOS on a PC configuring
the PCI/CardBus silicon, the NET2280 can itself act as the
PCI Host, with configuration information coming from its
internal 8051 CPU or from the USB Host. Auto-Enumeration
Technology allows a standard USB Host to detect this new
USB device even if no firmware has been run. This means
that firmware can actually be downloaded to the USB device
after initial boot-up.
The NET2280 includes PCI clock, reset, interrupt, and
arbitration pins to compensate for the other components
usually found in a typical PCI Host environment.
The NET2280 Reference Design Kit
The NET2280-RDK includes a PCI Board that easily plugs
into any standard PCI slot (3.3V or 5V). This board also
includes an optional PCI slot for plugging other PCI boards
into the RDK board itself. That would be for those
applications where the NET2280 will be the PCI Host.
Both USB Host and Peripheral side software is included with
the NET2280-RDK. The Host side software consists of
generic USB client drivers and several test and development
applications. The peripheral side firmware is used to
configure the NET2280 to resemble a standard USB class
device (like a printer or mass storage device) for which no
USB Host driver will need to be written. For custom, vendor-
specific applications, the Firmware API is provided to abstract
USB operation to standardized function calls. While this
software is available for various operating systems, it is
written in standard C with portability in mind. An included
porting guide aids USB developers through the entire porting
process.
