1 / 66 page 1/66 STE10/100 September 1999 This is preliminary information on a new product now in development. Details are subject to change without notice. 1.0 DESCRIPTION The STE10/100 is a high performance PCI Fast Eth- ernet controller with integrated physical layer inter- face for 10BASE-T and 100BASE-TX application. It was designed with advanced CMOS technology to provide glueless 32-bit bus master interface for PCI bus, boot ROM interface, CSMA/CD protocol for Fast Ethernet, as well as the physical media interface for 100BASE-TX of IEEE802.3u and 10BASE-T of IEEE802.3. The auto-negotiation function is also supported for speed and duplex detection. The STE10/100 provides both half-duplex and full- duplex operation, as well as support for full-duplex flow control. It provides long FIFO buffers for trans- mission and receiving, and early interrupt mecha- nism to enhance performance. The STE10/100 also supports ACPI and PCI compliant power manage- ment function. 2.0 FEATURES 2.1 Industry standard s IEEE802.3u 100BASE-TX and IEEE802.3 10BASE-T compliant s Support for IEEE802.3x flow control s IEEE802.3u Auto-Negotiation support for 10BASE-T and 100BASE-TX s PCI bus interface Rev. 2.2 compliant s ACPI and PCI power management standard compliant s Support PC99 wake on LAN 2.2 FIFO s Provides independent transmission and receiving FIFOs, each 2k bytes long s Pre-fetches up to two transmit packets to minimize inter frame gap (IFG) to 0.96us s Retransmits collided packet without reload from host memory within 64 bytes. s Automatically retransmits FIFO under-run packet with maximum drain threshold until 3rd time retry failure without influencing the registers and transmit threshold of next packet.
