IP Dragon II

The IP Dragon II is our second generation ethernet interface module based on the popular ethernet controller CS8900A from Cirrus logic.

The IP Dragon II is fully equiped to give any 8 or 16-bit system full ethernet capability. It features a selectable 8-bit or 16-bit databus interface, chip select and read/write signals. The board has two rows (2 x 15) of pins making it very easy to mount in an experiment system or a production system. The RJ-45 connector integrates both the inductor and two LED's that shows the link activity.

With this module your are ready to start implementing ethernet and internet communication on your embedded system in no time. Drivers for various TCP/IP stacks can be found on our download page.

General Information:

The IP Dragon is equiped with the Cirrus Logic embedded ethernet controller CS8900A. This ethernet controller is a flexible and powerful controller that can be used for embedded applications. Many other controllers on the market is targeted to the PCI bus and PC's making them very complex if not impossible to adapt to a low cost embedded system.

The module should connect to an MCU or CPU as a standard memory with the 8 or 16 -bit databus, IOR, IOW and CS signal. The module also supports interrupts in 16-bit mode.

A small serial EEPROM connected to the controller can be used to store the ethernet address and other controller related data. The EEPROM is only supported in 16-bit mode.

8 or 16 -bit databus is easily selected by moving a jumper.
