[TMI] Functional Description The TC9021/TC9020 is part of a new generation of high performance, host-optimized network interface cards designed for mission critical systems such as servers and high-end workstations. Offering two gigabits per second of aggregate bandwidth, the TC9021/TC9020 optimizes performance while minimizing network overhead on the host system. Compared to leading Fast Ethernet solutions, the TC9021/TC9020 transfers data at less than one tenth of the host CPU utilization rate. Features ❑ IEEE 802.3z compliant MAC supporting full wire speed at 1Gbps ❑ 1000Mbps, 100Mbps, and 10Mbps triple speed support ❑ GMII, MII or TBI interface with integrated 1000BASE-X PCS with Auto-Negotiation ❑ Half duplex carrier extension and packet bursting ❑ Scatter/gather DMA capable of 1Gbps transaction ❑ 32/64-bit PCI bus support--- TC9021 32-bit PCI bus support --- TC9020 ❑ TCP/UDP/IP checksum offloading ❑ Minimize interrupts ❑ Supports “interrupt-less” transmit operation ❑ Support for IEEE 802.1p prioritizing via priority queuing and interrupts ❑ Extensive IEEE 802.1Q VLAN support ❑ Jumbo frame support ❑ Provides a variety of flexible receive filtering modes, including VLAN, IP multicast, and hash table ❑ Flash ROM interface for remote network boot ❑ ACPI and wake On LAN support ❑ Windows NT 4.0, Windows 9x, Windows 2000, Novell Netware 4.x/5.x, Linux 2.x ❑ Low power 2.5/3.3V CMOS design with 5V tolerant I/O ❑ 0.25um CMOS technology ❑ 208-pin PQFP
