VSC7556TSN-V/5CC

Telecom Overview

The VSC7556TSN-V/5CC is a SparX-5i-160 Industrial Ethernet switch IC from Microchip Technology, designed for Time-Sensitive Networking (TSN) and scalable IIoT networks. It supports non-blocking switching bandwidths ranging from 64 Gbps to 200 Gbps across the family. This specific model features flexible interface options including 1G, 2.5G, 5G, 10G, and 25G Ethernet ports. Key specifications include an integrated 1 GHz dual-core Arm CPU with DDR3/DDR4 SDRAM controller, PCIe 2.0/3.0 interface, and internal shared memory buffers with eight queues per port. The device operates within an industrial temperature range of –40°C to 110°C.

Telecom Feature Summary

• Supports complete TSN feature set including time-aware shaping, cyclic queuing, stream policing, and high-precision time synchronization via VeriTime and SyncE.
• Provides fully managed Layer 2 switching and Layer 3 routing capabilities with IEEE 802.1Q VLAN support and secure MAC addressing.
• Integrates a powerful 1 GHz dual-core Arm processor enabling full management of industrial Ethernet solutions and seamless third-party software integration.

Telecom Applications

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

Telecom Procurement Notes

Verify component authenticity through authorized Microchip distributors or direct channels. Confirm package integrity upon receipt, as the FC-BGA-888 requires careful handling. Ensure compatibility with existing PCB layouts and thermal management designs before finalizing orders. Request official datasheets and errata documents to validate latest revisions.

Telecom Selection Notes

Select this model when requiring high-bandwidth industrial switching with comprehensive TSN capabilities. Compare against lower-tier SparX-5i variants like VSC7546TSN if reduced port counts suffice. Consider the integrated PoE controller and ARM processing power for complex edge computing tasks. Verify DDR3/DDR4 memory requirements and PCIe interface availability in the host system design.

Telecom Part Context

This part belongs to the SparX-5i family, which includes models such as VSC7546TSN, VSC7549TSN, VSC7552TSN, and VSC7558TSN. These devices share common architectural features but differ in port configurations and switching bandwidth capacities. The family targets industrial applications demanding deterministic networking and robust performance.

Telecom Replacement Considerations

Direct substitutes within the same family include VSC7552TSN and VSC7558TSN, depending on required bandwidth and port density. Cross-family replacements are not recommended due to significant architectural differences. Always verify pinout compatibility and software API support before substituting components.
