21143 PCI/CardBus 10/100 Ethernet LAN Controller Preliminary Datasheet

The Intel 21143 PCI/CardBus 10/100 Mb/s Ethernet LAN Controller (21143) supports the peripheral component interconnect (PCI) bus or CardBus. It provides a direct interface connection to the PCI bus and adapts easily to the CardBus and most other standard buses. The 21143 software interface and data structures are optimized to minimize the host CPU load and to allow for maximum flexibility in the buffer descriptor management. The 21143 contains large onchip FIFOs, so no additional onboard memory is required. The 21143 also provides an upgradable boot ROM interface.
