VSC7549TSN-V/5CC

Overview

The VSC7549TSN-V/5CC is a SparX-5i-90 industrial Ethernet switch IC from Microchip Technology. It provides up to 64 Gbps non-blocking switching bandwidth and supports flexible interface options including 1G, 2.5G, 5G, 10G, and 25G Ethernet ports. The device features an integrated 1 GHz dual-core Arm CPU with DDR3/DDR4 SDRAM controller and PCIe 2.0/3.0 interface. It operates within an extended temperature range of -40°C to +110°C and utilizes a 25 mm × 25 mm BGA package.

Feature Summary

• Supports complete Time-Sensitive Networking (TSN) feature set including time-aware shaping, cyclic queuing, stream policing, and high-precision time synchronization for deterministic communication.
• Provides fully managed Layer 2 switching and Layer 3 routing capabilities with IEEE 802.1Q VLAN support, secure MAC addressing, and hardware-based classification via VCAP technology.
• Integrates an internal shared memory buffer system with eight queues per port, supporting jumbo frames and strict priority/DWRR scheduling for efficient traffic management.

Applications

• Factory, building, and substation automation
• Process control systems
• Physical security networks
• Intelligent transportation systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm that the required software development package and API compatibility align with your existing Linux Distributed Switch Architecture or third-party software investments before finalizing procurement.

Selection Notes

Select this model when a configuration supporting 48 copper ports and four optical ports is required within the SparX-5i family. Ensure the design accommodates the necessary DDR3/DDR4 memory components and PCIe host interface. Verify that the application requires the specific 64 Gbps bandwidth ceiling rather than higher-tier models like the VSC7558TSN.

Part Context

This component belongs to the SparX-5i family of industrial Ethernet switches, which ranges from 64 Gbps to 200 Gbps switching capacities. It serves as a mid-range solution in the lineup, positioned between the VSC7546TSN and higher-bandwidth variants like the VSC7552TSN, targeting dense port count applications.

Replacement Considerations

Direct functional substitutes within the same family include the VSC7546TSN for lower port counts or the VSC7552TSN for higher bandwidth requirements. Cross-family migration to Ocelot switches may require significant architectural changes due to differing processing capabilities and interface sets.

FAQ

Does the VSC7549TSN support seamless redundancy protocols?

Yes, the device supports seamless redundancy features including Ethernet Ring Protection Switching (ERPS) and low-latency preemption through IEEE 802.1Qbu.

What timing synchronization standards are integrated into this switch?

The switch integrates VeriTime™ for IEEE 1588v2 precision time protocol and SyncE (Synchronous Ethernet) for high-precision time synchronization.
