| BCM5700 (R) 10/100/1000BASE-T CONTROLLER WITH INTEGRATED TRANSCEIVER BCM5700 FEATURES * Single-chip solution for LAN on Motherboard (LOM) and network interface card (NIC) applications * Integrated 10BASE-T/100BASE-TX/1000BASE-T transeivers * 10/100/1000 triple-speed MAC * Host interfaces - PCI v2.2, 32/64-bit, 33/66 MHz - PCI-X v1.0 64-bit, 133 MHz * Ultra-deep, 96 KB, on-chip packet buffer * Dual, high-speed RISC cores with 16 KB caches * Support for IEEE 802.3, 802.3u, 802.3z, and 802.3ab standards * MII/GMII and TBI (SerDes style) transceiver interfaces SUMMARY OF BENEFITS * Features wire speed operation at all speeds. * The BCM5700 is ideal for new high-speed network interface * * * * Advanced CPU offload features include: TCP/UDP/IP checksum offload, TCP segmentation, 9 KB jumbo frame * Dual high-speed CPUs * Microsoft(R) PC99 compliant: support for ACPI ver 1.1a, Wake on LAN, PXE version 2.0, and statistics for SNMP MIB II, Ethernet-like MIB, and Ethernet MIB (802.3z, Clause 30) * Low-power, 0.13 m CMOS design * * * * * * * * * Layer 2 priority encoding (802.3p) (up to 16 priority queues) VLAN tagging (IEEE 802.3q) Flow control (IEEE 802.3x) Link aggregation (IEEE802.3ad) cards (NIC) and LAN on Motherboard (LOM) applications, while maintaining backward compatibility with today's networks. Support for both the PCI 2.2 and PCI-X standard enables the BCM5700 to run in any PCI-based or PCI-X systems. The ultra-deep on-chip packet buffer allows the BCM5700 to continuously transmit and receive at high speeds in systems where the PCI/PCI-X bus is shared with other devices. On-chip CPUs perform advanced functions and allow the BCM5700 to evolve with new standards. The CPUs also provide advanced packet parsing capabilities, making the BCM5700 an OSI L4 protocol aware device, providing many advanced features and offloads. Advanced offload features promote high throughput, while minimizing host CPU utilization. Combined with the BCM5401 and newer Broadcom 10/100/ 1000BASE-T PHYs, the BCM5700 supports ACPI- compliant Wake on LAN implementations. Additional manageability features enable NIC and LOM designs to comply with relevant manageability standards for server and desktop applications. Provides low power operation--0.18 m advanced process technology, combined with programmable power management. Multiple power modes with programmable low power operation * 388-pin PBGA package * 5V tolerant PCI I/Os * Low power design - 3.3 V/1.8 V, 0.18 m CMOS BCM5700 10/100/1000 PIC-X NIC Reference Design BCM5700 OVERVIEW Receive GMII Receive MAC 128 FIFO Rule Check 96 KB Packet Buffer Memory Queue Memory Registers Statistics Frame Buffer Manager Transmit GMII Transmit MAC 128 FIFO Memory Arbiter Receive DMA ScratchPad Memory Boot Processor Transmit DMA Boot ROM TX Processor Ring Controllers Host Coalescing Queue Mangement SSRAM Control EEPROM Control Send BD RING Receive BD RING DMA Descriptor Config 512 FIFO PCI/ PCI-X 512 FIFO PCI/PCI-X Bus ScratchPad Memory PLL LED Control 125 MHz Clock LED Signals SSRAM Interface EEPROM Interface The BCM5700 is a high-performance 10/100/1000BASE-T Ethernet LAN controller optimized for NIC and LOM applications. The BCM5700 is a highly-integrated solution combining 10/100/ 1000BASE-T IEEE 802.3 compliant media access controller (MAC), PCI and PCI-X bus interfaces, and on-chip buffer memory in a single device. The BCM5700 is fabricated in a low voltage 1.8V CMOS process, providing a low-power system solution. Combine the BCM5700 with the BCM5401 (or later) single-chip Gigabit Ethernet transceiver to achieve a complete NIC or LOM solution for 10/100/ 1000BASE-T Ethernet. The BCM5700 includes a 10/100/1000-Mbps Ethernet MAC with full/ half-duplex capability at all speeds. The MAC interacts with the external transciever via the GMII in 1000BASE-T mode, the MII in 10/ 100BASE-T mode, and the TBI serial interface in 1000BASE-SX/ 1000BASE-FX mode. Support for the following 802.3 functions is featured in the MAC: VLAN tagging, layer 2 priority encoding, link aggregation, and full-duplex flow control. The device provides both PCI v2.2 and PCI-X v1.0 bus interfaces. The BCM5700 provides a large on-chip buffer memory for stand-alone operation, and optionally supports up to 16 MB of external memory. Dual, on-chip, high-performance processors enable custom frame processing features, including TCP segmentation.
