General Description
DP83816-EX is a single-chip 10/100 Mb/s Ethernet
Controller for the PCI bus. It is targeted at single board
computers for embedded applications requiring a high
speed PCI bus. The DP83816-EX 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-EX can support full
duplex 10/100 Mb/s transmission and reception, with
minimum interframe gap.
The DP83816-EX 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. Features
— IEEE 802.3 Compliant, PCI V2.2 MAC/BIU supports
traditional data rates of 10 Mb/s Ethernet and 100 Mb/s
Fast Ethernet (via internal phy)
— Bus master -burst sizes of up to 128 dwords (512 bytes) …
