Introduction
The Intel
Ethernet Media Access Control (MAC) and physical layer (PHY) functions. For embedded
communication and network devices such as web kiosks, and Point-of-Sale terminal designs with
critical space constraints, the Intel 82541ER allows for a Gigabit Ethernet implementation in a very
small area that is footprint compatible with current generation 10/100 Mbps Fast Ethernet designs.
The Intel
physical layer circuitry to provide a standard IEEE 802.3 Ethernet interface for 1000BASE-T,
100BASE_TX, and 10BASE-T applications (802.3, 802.3u, and 802.3ab). The controller is
capable of transmitting and receiving data at rates of 1000 Mbps, 100 Mbps, or 10 Mbps. In
addition to managing MAC and PHY layer functions, the controller provides a 32-bit wide direct
Peripheral Component Interconnect (PCI) 2.3 compliant interface capable of operating at 33 or 66
MHz.
The 82541ER Architecture is designed for high performance and low memory latency. Wide
internal data paths eliminate performance bottlenecks by efficiently handling large address and
data words. The 82541ER controller includes advanced interrupt handling features to limit PCI bus
traffic and a PCI interface that maximizes efficient bus usage. The 82541ER uses efficient ring
buffer descriptor data structures, with up to 64 packet descriptors cached on chip. A large 64 KByte
on-chip packet buffer maintains superior performance as available PCI bandwidth changes. In
addition, using hardware acceleration, the controller offloads tasks from the host controller, such as
TCP/UDP/IP checksum calculations and TCP segmentation.
The 82541ER is packaged in a 15 mm X 15 mm 196-ball grid array and is pin compatible with the
82559ER/82551ER 10/100 Mbps Fast Ethernet Multifunction PCI/CardBus Controller, 82562EZ/
82562EX Platform LAN Connect devices, the 82540EM Gigabit Ethernet Controller and the
82540EP Gigabit Ethernet Controller.
