5 Port 10M/100M Ethernet Switch
FEATURES
GENERAL DESCRIPTION
• IEEE802.3 and IEEE802.3u compliant.
• Provide 4 RMII and 1 MII/RMII ports.
• Programmable 1K/8K MAC addresses filtering.
• Store and forward switching function and bad
packet filtering function.
• Optional back_pressure/802.3x flow control/
flooding control/broadcast control.
• Optional EEPROM Interface for advanced
switch configurations.
• 1MB/2MB SGRAM/SDRAM flexible memory
interface.
• Port VLAN/trunking.
• Link/Rx activity, packet buffer utilization LED
display.
• 50MHz for non-blocking for 5 ports switch oper-
ation
• Build in internal/external memory test function.
• 128 pin PQFP package, 3.3V operation volt-
age.
The MTD505 complies fully with the
IEEE802.3, 802.3u and 802.3x specifications and
is a non-blocking 5 port 10M/100M Ethernet
switch device.
Support 4 RMII and 1 MII/RMII ports for
10M/100M operation. 1MByte/2MBytes memory
interface provides maximum 1365 packet buffers
for Ethernet packet buffering. Up to 8192 address
entrys are provided by the MTD505, and the
MTD505 use full Ethernet address compare algo-
rithm to minimize hashing collision events.
The MTD505 provides EEPROM interface
to config port trunking, port VLAN, static entry,
802.3x flow control threshold, flooding port,
broadcast control threshold. Each MTD505 port
support 10/100M auto-negotiation by MDC/MDIO
interface for connecting external PHY devices.
The MTD505 also provides 10 pins for
Link/RX activity, packet buffer utilization LED dis-
play function.
