DP83816 is a single-chip 10/100 Mb/s Ethernet Controller for the PCI bus. It is targeted at low-cost, high volume PC motherboards, adapter cards, and embedded systems. The DP83816 fully implements the V2.2 33 MHz PCI bus interface for host communications with power management support. Packet descriptors and data are transferred via bus-mastering, reducing the burden on the host CPU. The DP83816 can support full duplex 10/100 Mb/s transmission and reception, with minimum interframe gap.
The DP83816 device is an integration of an enhanced version of the National Semiconductor PCI MAC/BIU (Media Access Controller/Bus Interface Unit) and a 3.3V CMOS physical layer interface.
