RTL8391M-CG中文资料LAYER 2 + MANAGED 28 10/100/1000M-PORT SWITCH CONTROLLER数据手册Realtek规格书

描述 Description

The RTL8391M is a 28-port 10/100/1000M Managed Ethernet MAC Switch Controller. It supports 7 pairs of 5Gbps QSGMII to connect to external 28 ports Gigabit Ethernet PHY transceivers. The mode is 24 10/100/1000BASE-T + 4 combo 10/100/1000BASE-T/SFP.
The RTL8391M is embedded with a up to 700MHz MIPS-34Kc CPU. It supports a 32-bit data bus, 32Mbyte SPI flash (3-byte mode) or 64MB SPI flash (4-byte mode), and 256M-Byte DDR3 SDRAMs (maximum). It is also embedded a 96KB SRAM can be used for time-sensitive application.
