Design Applications
Add a USB Device Port to PCI-Based Systems
The NET2282 can be used to easily add a USB 2.0 peripheral
port to a PCI based embedded system. The standard PCI
interface of the NET2282 connects gluelessly to any PCI bus.
Standard PCI registers allow the existing BIOS to configure
and send data to and from the NET2282.
Firmware is available to configure the NET2282 to resemble a
standard USB class device (like a printer or mass storage
device) for which no USB host drivers will need to be written.
For custom applications, firmware APIs are provided to
abstract the USB transactions to reads and writes. This
firmware is available for various operating systems.
Migrate PCI and CardBus Designs to USB
The NET2282 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 NET2282 connects gluelessly with them.
Instead of a PCI host chipset and BIOS on a PC configuring
the PCI/CardBus silicon, the NET2282 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 NET2282 includes PCI clock, reset, interrupt, and
arbitration pins to compensate for the other components
usually found in a typical PCI host environment. Shared
memory in the NET2282 functions as main memory for
holding descriptors or other control data. The integrated 8051
CPU can also be used to configure the device to resemble a
standard USB class device (like a communications or video
device) even if there is no local intelligence on the peripheral.

NET2282-RDK
The NET2282 Rapid Development Kit
The NET2282RDK 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 NET2282 will be the PCI host.
Both USB host and peripheral-side software is included with
the NET2282RDK. The host-side software consists of USB
drivers and test applications. The peripheral-side firmware is
used to configure the NET2282 to resemble a standard USB
class device (like a printer or mass storage device) for which
no USB host drivers will need to be written. For custom
applications, firmware APIs are provided to abstract the USB
transactions to reads and writes. While this software is
available for various operating systems, it is written in
standard C with portability in mind. A porting guide is
shipped with the kit.
