DESCRIPTION
The STE10/100 is a high performance PCI Fast Ethernet controller with integrated physical layer interface for 10BASE-T and 100BASE-TX application.

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 bus interface Rev. 2.2 compliant
■ ACPI and PCI power management standard compliant
■ Support PC99 wake on LAN

FIFO
■ Provides independent transmission and receiving FIFOs, each 2k bytes long
■ Pre-fetches 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 3rd time retry failure without influencing 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 and 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
■ As bus master, supports memory-read, memory-read-line, memory-read-multiple, memory-write, memory-write-and-invalidate command
■ Supports big or little endian byte ordering

EEPROM/Boot ROM I/F
■ Provides writeable Flash ROM and EPROM as boot ROM, 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
■ Provides serial interface for read/write 93C46 EEPROM
■ Automatically loads device ID, vendor ID, subsystem ID, subsystem vendor ID, Maximum-Latency , and Minimum-Grand from the 64 byte contents of 93C46 after PCI reset de-asserted

MAC/Physical
■ Integrates the complete set of Physical layer 100BASE-TX and 10BASE-T functions
■ Provides Full-duplex operation in both 100Mbps and 10Mbps modes
■ Provides Auto-negotiation (NWAY) function of full/half duplex operation for both 10 and 100 Mbps
■ Provides MLT-3 transceiver with DC restoration for Base-line wander compensation
■ Provides transmit wave-shaper, receive filters, and adaptive equalizer
■ Provides MAC and Transceiver (TXCVR) loop-back modes for diagnostic
■ Built-in Stream Cipher Scrambler/ De-scrambler and 4B/5B encoder/decoder
■ Supports external transmit transformer with 1.414:1 turn ratio
■ Supports external receive transformer with 1:1 turn ratio
