PRODUCT BRIEF Infineon's Purple (PLB 2800) is a highly integrated and configurable Layer 2+ SoC (Switch-on-a-Chip). It extends Infineon's Layer 2 Ethernet switch family of products for higher integration, and more advanced traffic management. The Purple’s versatile configuration and stacking options permit a variety of system topologies designed to increase the deployment of Ethernet access applications. The Purple features a large on-chip packet buffer and address tables. With the addition of an on-chip 64-bit MIPS CPU, the need for an external memory and controller is eliminated. Advanced security and Quality of Service (QoS) features are guaranteed using extensive VLAN management capabilities and port-based security for guarded and secure handling of traffic flows. The Purple supports seven different configurations, ranging from eight GbE ports up to 48FE + 2GbE.
