RTL8198 datasheet

 

Description

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.

Features

1. Embedded RISC CPU, RLX5281 with 16K I-Cache, 8K D-Cache, 40K I-MEM, 8K D-MEM

2. Supports MIPS-1 ISA, MIPS16 ISA

3. Clock rate up to 500MHz

4. Provides a standard 5-signal P1149.1 EJTAG test port

5. Supports RLX5281 CPU suspend mode
