AN983B Datasheet, PDF (11/91 Pages) List of Unclassifed Manufacturers – PCI/miniPCI-to-Ethernet LAN Controller

AN983B PCI/miPCI Fast Ethernet Controller with integrated PHY
3. FEATURES
INDUSTRY STANDARD
IEEE802.3u 100BASE-TX and IEEE802.3 10BASE-T compliant
Support for IEEE802.3x flow control
IEEE802.3u Auto-Negotiation support for 10BASE-T and 100BASE-TX
PCI Specification 2.2 compliant
ACPI and PCI power management Ver.1.1 compliant
Support PC99 wake on LAN
FIFO
Provides two independent long FIFOs with 2k bytes each for transmission and receiving
Pre-fetch up to two transmit packets to minimize inter frame gap (IFG) to 0.96us
Retransmits collided packet without reload from host memory within 64 bytes.
Automatically retransmits FIFO under-run packet with maximum drain threshold until 3
times retry failure and that will not influence the registers and transmit threshold of next
packet
PCI I/F
Provides 32-bit PCI bus master data transfer
Supports PCI clock with frequency from 0Hz to 33MHz
Supports network operation with PCI system clock from 20MHz to 33MHz
Provides performance meter, PCI bus master latency timer, for tuning the threshold to
enhance the performance
Provides burst transmit packet interrupt and transmit/receive early interrupt to reduce
host CPU utilization
Supports memory-read, memory-read-line, memory-read-multiple, memory-write,
memory-write-and-invalidate command while being bus master
Supports big or little endian byte ordering
EEPROM/BOOT ROM I/F
Provides write-able Flash ROM and EPROM as boot ROM with size up to 128kB
Provides PCI to access boot ROM by byte, word, or double word
Re-writes Flash boot ROM through I/O port by programming register
