PLB 2800
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 versa-
tile 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 configura-
tions, ranging from eight GbE ports up to
48FE + 2GbE.
