Product details
Overview
VSC7552TSN-V/5CC from Microchip is a SparX-5i-128 industrial Ethernet switch IC supporting up to 128 Gbps nonblocking switching bandwidth, full L2/L3 forwarding, IEEE 802.1Qbv/802.1AS-Rev TSN compliance, and operation from –40°C to +110°C. It integrates a 1 GHz dual-core Arm® CPU, DDR3/DDR4 memory controller, and VCAP-II classification engine for deterministic traffic shaping in factory automation networks.
For engineers reviewing the VSC7552TSN-V/5CC datasheet, VSC7552TSN-V/5CC pinout, VSC7552TSN-V/5CC application, or VSC7552TSN-V/5CC equivalent, key selection criteria include TSN feature completeness (802.1Qbv, 802.1AS-Rev, 802.1CB), industrial temperature support, integrated VeriTime™ PTP timing, PCIe 2.0/3.0 host interface, and 25 mm × 25 mm BGA-529 package compatibility.
Technical Context
The VSC7552TSN-V/5CC implements multistage VCAP-II content-aware processing for per-port VLAN tag manipulation, ACL enforcement, and QoS shaping with strict priority and DWRR scheduling. It supports hardware-accelerated L2 switching (32K MAC entries, 4K VLANs) and L3 unicast/multicast routing with TCAM-based classification.
Its timing subsystem integrates VeriTime™ (IEEE 1588v2) and SyncE for sub-100 ns time synchronization across TSN domains, while ERPS and seamless redundancy protocols ensure <50 ms failover in ring topologies. The device uses PCIe 2.0/3.0 for host CPU communication and includes JTAG, SPI, and GPIO interfaces for system management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar industrial TSN switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VSC7556TSN-V/5CC | Higher 160 Gbps bandwidth; adds two additional 25G SerDes lanes and expanded TCAM capacity | Better suited for 25G-heavy deployments (e.g., AI edge inference nodes) requiring >128 Gbps aggregate throughput | Select when scaling beyond 128 Gbps or requiring additional USXGMII/25G optical ports |
| VSC7549TSN-V/5CC | 90 Gbps bandwidth; fewer SerDes lanes, reduced TCAM depth, no 25G support | Targeted at cost-sensitive 1G/10G-only deployments where full TSN feature set remains required | Select when 90 Gbps bandwidth suffices and 25G interfaces are unnecessary |
Compared with VSC7552TSN-V/5CC, the VSC7556TSN-V/5CC offers higher bandwidth and SerDes count for future-proofing, while the VSC7549TSN-V/5CC reduces cost and complexity for 1G/10G-centric IIoT gateways-both retain identical TSN feature implementation and VeriTime™ timing architecture.
