Preliminary T71L6808A
Octal 10/100 Switch
with Embedded Memory
The T71L6808A is an octal-port 10/100Mbps dual speed Ethernet switch integrated both with an
embedded SSRAM and a 1K entries of address table. A high performance Fast Ethernet switch,
fully complies with the IEEE802.3, 802.3u and 802.3x specifications, can be implemented using the
T71L6808A with physical devices. The T71L6808A is intended for applications to stand-alone
switch for low-cost SOHO market.
Features
Supports eight 10/100Mbps Ethernet ports with RMII interface
Fully non-blocking shared memory architecture using page-based embedded SSRAM.
Incorporating with the output private buffering scheme to prevent HOL (head of line) blocking
Wire-speed store-and-forward switching with low switching latency. Automatic address
learning, local frames filtering, and adjustable aging
Embedded 1K entries of look-up table
Supports full and half duplex operations
Link, speed and duplex status are auto-detected via MDIO
Auto-negotiated Full-duplex flow control by writing the ability via MDIO to external PHY
Supports IEEE 802.3x flow control for full-duplex operation
Supports back-pressure flow control for half-duplex operation
Serial EEPROM interface for auto-configuration
Broadcast storm control
Port trunking & load sharing
Port-based VLAN
Port monitoring(snooping or mirroring)
Supports port priority per port basis QoS
Only one 50MHz OSC
128-pin PQFP, 3.3V CMOS technology
