DP83816 is a 10/100 Mb/s integrated PCI Ethernet Media Access Controller and Physical Layer (MacPHYTER-II™) produced by National Semiconductor Corporation, targeting low-cost, high volume PC motherboards, adapter cards, and embedded systems.
The document describes the National Semiconductor DP83816, a single-chip 10/100 Mb/s Ethernet controller targeting low-cost PC motherboards, adapter cards, and embedded systems. It fully implements the V2.2 33 MHz PCI bus interface for host communications with power management support.
The chip integrates an enhanced version of the National Semiconductor PCI MAC/BIU (Media Access Controller/Baseband Interface Unit) and a 3.3V CMOS physical layer compliant with IEEE 802.3u. Key features include full duplex transmission, internal FIFOs for data buffering, and support for Wake on LAN (WOL), VLAN, and Auto-Negotiation.
The device supports full duplex transmission and reception at both 10 Mb/s and 100 Mb/s.
The device supports bus master burst sizes of up to 128 dwords, which equals 512 bytes.
