The Realtek RTL9301 is a highly integrated Layer3 switch supporting Energy Efficient Ethernet (EEE). It has up to 24-port Gigabit and 4-port 10G Ethernet MACs. It also provides 4 pairs of 8Gbps SerDes interface to connect with another RTL9301 to extend to a 48-port Gigabit and 4-ports 10G Ethernet transceiver. There are two mode selections in the RTL9301. One is 24*10/100/1000Base-T + 4*10G Base-R; the other is 48*10/100/1000Base-T + 4*10G Base-R. The RTL9301 supports up to 16 devices stacking.
The RTL9301 is embedded with an up to 800MHz MIPS-34Kc CPU. It supports a Maximum 64Mbyte SPI NOR Flash, and 1G-Byte DDR3 SDRAMs (maximum). An embedded 64KB SRAM can be used for time-sensitive applications.
