VSC7549-V/5CC

Overview

The VSC7549-V/5CC is a SparX-5 Enterprise Ethernet switch supporting up to 90 Gbps bandwidth. It features 64 maximum ports, including configurations of 9x10G, 16x2.5G+4x10G, or 48x1G+4x10G. The device integrates a dual-core 1 GHz ARM Cortex-A53 CPU and a dedicated ARM Cortex-M3 core. Key parameters include 32 Mb packet buffer, 32K MAC table entries, 511 router legs, 2K next-hop/ARP entries, and 64 VRF-Lite instances. It supports IPv4/IPv6 L2/L3 forwarding, TCAM-based security via VCAP, and IEEE 802.1Qbb Priority-Based Flow Control.

Feature Summary

• Integrates a powerful dual-core 1 GHz ARM Cortex-A53 CPU for full management and advanced applications alongside a dedicated ARM Cortex-M3 core for bootup and PoE tasks.
• Provides Layer 2 and Layer 3 forwarding capabilities with TCAM-based VLAN/QoS processing and Versatile Content Aware Processor (VCAP) for security frame processing.
• Supports flexible port configurations including 10G aggregation links, QSGMII, USGMII, and USXGMII interfaces for high-density switching environments.

Applications

• Enterprise L2 managed and L2/L3 (L3-Lite) managed equipment
• WiFi aggregation points
• Security appliances
• Base stations and baseband processor interconnect

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with required DDR3/DDR4 memory controllers and PCIe interface versions before procurement. Confirm that the selected SKU matches the necessary port density and routing table sizes for the target design.

Selection Notes

Select the VSC7549 when 90 Gbps bandwidth and higher port counts are required compared to the VSC7546. Evaluate the need for specific SerDes lane configurations and external memory requirements. Consider the integrated CPU subsystem for managing complex enterprise policies without external processors. Verify support for required tunneling protocols and multicast group capacities.

Part Context

The VSC7549 belongs to the SparX-5 family of L2/L3 Enterprise 10G Ethernet switches manufactured by Microchip Technology. It is designed for SMB, SME, and Enterprise applications requiring high port count switching with 10G aggregation. The family includes the VSC7546 variant with lower bandwidth capacity.
