RTL8196E Datasheet – Router Network Processor – Realtek

Part Number: RTL8196E


Package: LQFP 128 Pin

Manufacturer: Realtek




The RTL8196E is an integrated System-on-a-Chip(SoC) Application Specific Integrated Circuit (ASIC) L2 5-Port Ethernet switch. An RLX4181 CPU is embedded and the clock rate can be up to 400MHz. To improve computational performance, a 16Kbyte I-Cache, 8Kbyte D-Cache, 16Kbyte I-MEM, and 8Kbyte D-MEM are provided. A standard 5-signal P1149.1 compliant EJTAG test interface is supported for CPU testing and software development.

The device provides five ports (ports 0~4), integrated with fivephysical layer transceivers for 10Base-T and 100Base-TX. Each port of the RTL8196E may be configured as a LAN or WAN port. The RTL8196E supports flexible IEEE 802.3x full-duplex flow control and optional half-duplex backpressure control. For full-duplex, standard IEEE 803.3x flow control will enable pause ability only when both sides of UTP have auto-negotiation ability and have enabled pause ability. The RTL8196E also provides optional forced mode IEEE 802.3x full-duplex flow control. Based on optimized packet memory management, the RTL8196E is capableof Head-Of-Line blocking prevention.
