The DP83816 is a single-chip 10/100 Mb/s Ethernet Controller for the PCI bus, targeting 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.
The DP83816 is a single‑chip 10/100 Mb/s Ethernet controller for the PCI bus, aimed at low‑cost, high‑volume PC motherboards, adapter cards, and embedded systems. The handbook provides a complete description of the controller’s architecture, including MAC/BIU, physical layer, and power‑management features.
Key sections cover the connection diagram, pin description, functional description, buffer management, register set, power‑management and Wake‑On‑LAN, as well as detailed information on the Media Independent Interface and 100BASE‑TX/10BASE‑T interfaces.
