82573 Family of GbE Controllers
Datasheet
Product Features
PCIe*
— x1 PCIe* interface on ICH7 or MCH devices
Manageability
— Intel® Active Management Technology (Intel®
AMT) support (82573E only)
— Peak bandwidth: 2 Gb/s per direction
— Power management
— High bandwidth density per pin
— Alerting Standards Format 2.0 and advanced
pass through support (82573E/V only)
— Boot ROM Preboot eXecution Environment
(PXE) Flash interface support
MAC
— Optimized transmit and receive queues
— IEEE 802.3x compliant flow control with
software controlled pause times and threshold
values
— Compliance with PCI Power Management 1.1
and Advanced Configuration and Power
Interface (ACPI) 2.0 register set compliant
— Wake on LAN support
— Caches up to 64 packet descriptors per queue
— Programmable host memory receive buffers
(256 bytes to 16 KB) and cache line size (16
bytes to 256 bytes)
Additional
— Three activity and link indication outputs that
directly drive LEDs
— Programmable LEDs
— 32 KB configurable transmit and receive FIFO
— Internal PLL for clock generation that can use
buffer
a 25 MHz crystal
— Mechanism available for reducing interrupts
generated by transmit and receive operation
— Descriptor ring management hardware for
transmit and receive
— Power saving feature for the 82573L. During
the L1 and L2 link states, the 82573L asserts
the Clock Request signal (CLKREQ#) to
indicate that its PCIe* reference clock can be
gated
— Optimized descriptor fetching and write-back
mechanisms
— On-chip power control circuitry
— Loopback capabilities
— Wide, pipelined internal data path architecture
PHY
— JTAG (IEEE 1149.1) Test Access Port (TAP)
— Integrated PHY for 10/100/1000 Mb/s full and
built in silicon
half duplex operation

external regulators)
— DSP architecture implements digital
adaptive equalization, echo cancellation,
and cross-talk cancellation
— Operating temperature: 0° to 55° C (with on-
die 2.5V regulator)
— Storage temperature -40° C to 125° C
Host Offloading
— Transmit and receive IP, TCP and UDP
checksum off-loading capabilities
