RTL8198 datasheet



The RTL8198 is an integrated System-on-a-Chip (SoC) Application Specific Integrated Circuit (ASIC) that implements a L2 switch, L3 routing, and L4 NAT functions. An RLX5281 CPU is embedded and the clock rate can be 500MHz~620MHz. To improve computational performance, a 16-Kbyte I-Cache, 8-Kbyte D-Cache, 40-K I-MEM, and 8-Kbyte D-MEM are provided. A standard 5-signal P1149.1 compliant EJTAG test interface is supported for CPU testing and software development.

Via table configuration and look-up, the RTL8198 can perform hard-wired network traffic forwarding. The CPU may be used to handle upper layer functions, such as DHCP, HTTP, and some other protocols, and to operate with a hard-wired forwarding engine.
