100/10Mbps Ethernet Controller
W89C840AF is a highly integrated Ethernet LAN controller for both 100BaseT and 10BaseT Ethernet. It provides a host bus interface complying with the PCI local bus specification revision 2.1, and the MII interface complying with the IEEE802.3u standard for easily implementing an Ethernet LAN adapter. The built-in 2K bytes transmit FIFO and 4K bytes receive FIFO, controlled by the on-chip bus master, are designed for improving network performance and reducing the host bus utilitzation.
Features
• Complies with IEEE 802.3, 802.3u, ANSI 8802-3 and Ethernet standards
• Supports PCI bus master mode for DMA operation, fully complying with PCI 2.1 standard
• Compliant with APCI R1.0, PCI power management R1.0 and Network device Class Power
management Reference specification V1.0a
• Supports remote wakeup function
• Both half duplex and full duplex available for 10/100M operation
• Flexible data structure for host compatibility and system performance
• Supports 25 to 33 Mhz PCI clock speed
• Supports full MII management function
• Provides EEPROM and flash memory on-board programming function
• Supports both big and little endian byte ordering for descriptor and buffer
• Flexible address filtering modes
-- 64-bit hash-table and one perfect address
-- all multicast and promiscuous
• A boot ROM interface, capable of supporting up to 256KB
• Supports automatic loading configuration register
• Internal and external loopback mode for diagnostic
• Single 5 volt power supply
• 128 pins PQFP package
