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. Applications Ethernet access switch for IP-DSLAM/DLC/MDU/MTU High port count workgroup switch GbE aggregator Ethernet Switch Cellular base stations Packet over SONET/SDH systems Features 21 Gbit/s 12 million packets/ second switching engine for solid L2+ wirespeed switching performance Embedded 64-bit MIPS 5Kc CPU On-chip DRAM, SRAM Stackable with up to 16 Purple switches with complete stack management Four Class of Service (CoS) queues per port

Strict priority and Weighted-FairQueuing (WFQ) packet scheduling Advanced buffer control Broadcast and multicast storm control Multicast support for up to 256 multicast groups Port based flow control Per-flow token bucket policing Per-queue rate shaping Port, tag and flow-based VLANs Stacked VLAN support Port-based security Intrusion detection eCPU switch management with Bus mastering capabilities, flowbased accounting and RMON support Hardware assistance for protocols such as STP, GVRP and IGMP and Snooping
Interfaces SMII V1.2/V2.1 for FE ports (R)GMII/TBI/MII for GE ports 32-Bit, 66 MHz PCI or generic host bus with DMA support 2 I C Interface for configuration EEPROM, optional low-cost CPU PC-133 SDRAM interface for external CPU DRAM EJTAG Interface for testing General purpose timer and I/Os
Standards Supported Supports a wide variety of IEEE 802.xx protocols IETF RFCs 1155-1157 SNMP IETF RFCs 1213, 1643, 1493 IETF RFC 1757 RMON Physical Characteristics P-BGA-388-2 package Core logic operates at 1.8 V
