DP83815 DP83815 10/100 Mb/s Integrated PCI Ethernet Media Access Controller and
Physical Layer (MacPhyter) Literature Number: SNLS059E DP83815 10/100 Mb/s Integrated PCI Ethernet Media Access
Controller and Physical Layer (MacPhyterв„ў) DP83815 is a single-chip 10/100 Mb/s Ethernet Controller
for the PCI bus. It is targeted at low-cost, high volume PC
mother boards, adapter cards, and embedded systems.
The DP83815 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
DP83815 can support full duplex 10/100 Mb/s transmission
and reception, with minimum interframe gap. Features ol
e The DP83815 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. — Virtual LAN (VLAN) and long frame support
— Support for IEEE 802.3x Full duplex flow control
— Extremely flexible Rx packet filtration including: single
address perfect filter with MSb masking, broadcast, 512
entry multicast/unicast hash table, deep packet pattern
matching for up to 4 unique patterns
— Statistics gathered for support of RFC 1213 (MIB II),
RFC 1398 (Ether-like MIB), IEEE 802.3 LME, reducing
CPU overhead for management …
