Features
ü Three forwarding modes are supported : Store-
• Support 5 10/100 Mbps Ethernet ports with
RMII/MII interface
ü Provides packet switching functions between 5
10/100 Mbps, auto-negotiated ports
ü Ideal for SOHO switches and its application
• Build in 5-ports 10/100Mbps Switch engine with
following features
ü Low cost SSRAM interface to reduce system cost
ü One or two 64K*32bit SSRAM to buffer packets
ü 4/8 K MAC address look up Table is supported
ü Address mapping of look up table can be linear or
use hash algorithm
ü Auto learning and filtering
ü Aging the look up table is supported optionally
ü Aging time can be 1min to 640 mins 7 steps
and-Forward, Fragment-Free and Auto Forward
which is based on network quality
ü Flow-control is supported optionally
ü 802.3x flow control is supported when running in
full-duplex mode
ü Back-pressure base flow control is supported
when running in half-duplex mode
ü Ext. Buffer Memory auto testing
ü Routing and Learning at wire speed (148800
packets/sec at 100Mbps)
• LED display buffer utilization (%) for whole system
and external SSRAM test.
• Power on LED diagnosis. All the LED display will
follow the “ON-OFF-ON-OFF-Normal” operation
procedure during/after power on reset
• 60MHz Operation, 3.3volt, 208-pin PQFP
