NP1777-01.qxd 4/10/01 10:14 AM Page 1 Intel 82550 Fast Ethernet Multifunction PCI/CardBus Controller ® Product Brief Overview The Intel® 82550 Fast Ethernet Multifunction PCI/CardBus Controller is a third-generation, fully integrated, Fast Ethernet Media Access Controller (MAC)/Physical Layer (PHY) device. The MAC offers a low-cost, high-performance 10/100Mbps LAN solution. In addition, the 82550 requires low real estate, which is important when competing for precious board space. The 82550’s baseline functionality is equivalent to that of the 82559 with the addition of an integrated IP Security (IPSec) encryption engine and Alert on LAN* 2 functionality. Product Description The 82550, with an integrated IP Security (IPSec) encryption engine and Alert on LAN functionality, is Intel’s premium 10/100 network connectivity solution. It is designed for use in Network Interface Cards (NICs), PC LAN on Motherboard (LOM) designs, embedded systems, and networking systems products. The 82550 combines advanced security and manageability features to provide a secure and easily managed Fast Ethernet connectivity solution for today’s networked environment. The 82550 continues Intel’s platform LAN technology leadership by integrating the following features: Triple Data Encryption Standard (3DES) IPSec encryption engine, Alert on LAN 2 functionality and Advanced Configuration and Power Interface (ACPI) 1.2A-based power management. It also supports wake on Magic Packet*, wake on interesting packet, and advanced System Management Bus (SMB) manageability. The 82550 complies with Wired for Management (WfM) Specification 2.0, PC 01 and Server 00 specifications. The 82550 is pin compatible with the 82559, allowing these designs to be upgraded. Applications The 82550 is designed for use in the following applications:  LAN on Motherboard (LOM) implementations  Embedded applications  Network Interface Card (NIC) adapters  Networking systems Product Features    Enhanced IP Support – TCP, UDP, IPv4 checksum offload – Received checksum verification – IP Security support Quality of Service (QoS) – Multiple priority transmit queues Optimum Integration for Lowest Cost Solution – Integrated IP Security encryption engine – Integrated IEEE 802.3 10BASE-T and 100BASE-TX compatible PHY – 32-bit PCI/CardBus master interface – Modem interface for combination solutions – Integrated power management functions – Thin BGA 15 mm2 package  Wired for Management (WfM) and Reduced Total Cost of Ownership – Wired for Management support – Integrated Alert on LAN 2 support – Advanced Configuration and Power Interface and PCI power management specifications compliance – Wake on “interesting” packets and link status change support – Magic Packet support – Remote power-up support – High-performance networking functions – Early release – Chained memory structure similar to the 82559, 82558, 82557, and 82596 – Improved dynamic transmit chaining with multiple priorities transmit queues NP1777-01.qxd 4/10/01 10:14 AM Page 2 Product Features (cont.) – Backward compatible software to the 82559, 82558 and 82557 – Full-duplex support at both 10 and 100Mbps operation – IEEE 802.3u Auto-Negotiation support – 3 Kbyte transmit and 3 Kbyte receive FIFOs – Fast back-to-back transmission support with minimum interframe spacing – IEEE 802.3x 100BASE-TX Flow Control support – Adaptive Technology – Low-power features – Advanced Power Management (APM) capabilities – Low power +3.3V device – Efficient dynamic standby mode – Deep Power down support – Clockrun protocol support Features Benefits Improved IPSec encryption offload performance  Quicker encryption/decryption response times 82550GY 82550EY 82559 Integrated UNDI ROM support  Minimizes the need for an external ROM Improved Deep Power down power consumption levels  Greater MDIx and HWI Alerting  Assists Integrated IPSec encryption engine  Provides battery life on mobile platforms in troubleshooting network connectivity problems increased encryption performance versus software encryption only and eliminates need for a separate crypto component           ® Intel 82550 Fast Ethernet Multifunction PCI/CardBus Controller Integrated Alert on LAN* 2 functionality  Increased Combination 10/100Mbps Fast Ethernet controller and physical layer interface with glueless 32-bit PCI bus master interface  Provides  Wired for Management (WfM) and Net PC Specifications compliant  Advanced Configuration and Power Interface (ACPI) Specifications compliant  Magic Packet filtering for Wake on LAN*  Address Resolution Protocol (ARP) and flexible frame filtering  Enables Backwards compatible software drivers  Allows systems developed with the EtherExpress™ PRO/100B or 82557 to use the same device drivers  Robust, well-tested, high-performance drivers    Improved dynamic transmit chaining  Enhanced    Hardware IP checksum assist  Maximizes    Integrated management port  Enables    Enhanced power management  Minimizes     CardBus and modem support  Enables Common driver support  Allows        Alert on LAN functionality need for a separate Alert on LAN 2 device  Eliminates low-cost network connectivity for LOM or PCI adapters board space requirements and external support circuitry  Reduces PCs to be remotely managed for lower Total Cost of Ownership (TCO) various power down states and the ability to “wake-up” on a unique packet addressed to the system  Allows virtually connected IPv6, IPv4, Windows NT*, or next-generation systems  Provides system throughput by reducing CPU overhead under IP direct interface to future Total Cost of Ownership-enabled system chipsets power requirements combination CardBus LAN/modem designs common driver support across both PC card and NIC   Utilizes   Processes Programmable transmit threshold Early receive interrupt  Large internal receive and transmit buffers  FLASH memory support performance bus more efficiently receive data concurrently data overruns or underruns  Prevents  Enables back-to-back frame transmission within interframe spacing  Supports network management and remote boot Characteristics Electrical Power Supply  3.3V ± 5% Environmental Operating temperature  0ºC to +85ºC (maximum) Storage temperature  -65ºC to 140ºC Physical Package  196-pin BGA Information in this document is provided in connection with Intel® products.
