128-pin PQFP, 3.3V single power technology

The RTL8316 provides 16 10/100 Mbps RMII Ethernet ports. Each port can operate in a 10 Mbps or 100 Mbps data rate, and in full or half duplex mode. Speed, duplex, link status and flow control can be acquired by periodically polling the status of the PHY devices via MDIO.

Two ports can support Speed, Duplex and Flow-control abilities through force setting mode for fiber applications. The address look-up table consists of 8K entries of hash table and a 128 entries of CAM. The RTL8316 uses 13 bit MAC address direct mapping method to search the destination MAC address and record source MAC address from and to the hash table.
