Product details
Overview
VSC7558TSN-V/5CC from Microchip is a SparX-5i-200 industrial Ethernet switch IC supporting up to 200 Gbps nonblocking switching bandwidth, full L2/L3 forwarding, complete IEEE 802.1 TSN feature set (802.1Qbv, 802.1AS-Rev, 802.1CB), and operation from –40°C to +110°C. It integrates a 1 GHz dual-core Arm® CPU with DDR3/DDR4 controller and supports 1G/2.5G/5G/10G/25G Ethernet port configurations for time-critical factory automation networks.
For engineers reviewing the VSC7558TSN-V/5CC datasheet, VSC7558TSN-V/5CC pinout, VSC7558TSN-V/5CC application, or VSC7558TSN-V/5CC equivalent, key selection criteria include TSN compliance level, industrial temperature support, integrated VeriTime™ and SyncE timing, PCIe 3.0 host interface, and hardware-accelerated TCAM-based classification for deterministic traffic shaping in IIoT edge nodes.
Technical Context
The VSC7558TSN-V/5CC implements multistage VCAP-II content-aware processing for per-port VLAN tagging (up to two tags), ACL enforcement, and frame editing with strict priority and DWRR scheduling. Its internal shared memory buffer provides 8 queues per port and supports jumbo frames up to 9000 bytes.
It delivers hardware-based L3 unicast/multicast routing, ERPS ring protection, IGMP/MLD snooping, and IEEE 802.1Qci stream policing with per-flow rate limiting. The integrated VeriTime™ engine achieves sub-100 ns PTP timestamp resolution and supports 1588v2 transparent clock and boundary clock modes.

FAQ
What is the maximum number of 25G Ethernet ports supported by the VSC7558TSN-V/5CC?
The VSC7558TSN-V/5CC supports up to 20 × 25G Ethernet ports in full line-rate operation, enabled by its 200 Gbps nonblocking switching fabric. This configuration is validated in Microchip's SparX-5i-200 reference design and documented in DS00002854A. Port mapping is configurable via VCAP-II rules and software-defined SerDes lane assignment, allowing flexible 1G/2.5G/10G/25G combinations without hardware change.
Does the VSC7558TSN-V/5CC include hardware support for IEEE 1588 Precision Time Protocol?
Yes, the VSC7558TSN-V/5CC integrates VeriTime™, a hardware timestamping engine compliant with IEEE 1588-2008 and 1588-2019 (802.1AS-Rev). It delivers sub-100 ns timestamp resolution on all ports and supports boundary clock, transparent clock, and peer-to-peer transparent clock modes. This capability is intrinsic to the silicon and does not require external PHY or timing ICs.
What is the role of the dual-core Arm® CPU in the VSC7558TSN-V/5CC?
The dual-core Arm® Cortex-A9 CPU in the VSC7558TSN-V/5CC executes the full Linux-based management stack, hosts the IStaX™ software development framework, and handles L3 routing control plane functions. It operates at 1 GHz with integrated DDR3/DDR4 controller, enabling real-time SNMP, CLI, RESTful API, and web UI services while offloading packet forwarding to dedicated hardware engines.
Can the VSC7558TSN-V/5CC operate in environments exceeding 85°C ambient temperature?
Yes, the VSC7558TSN-V/5CC is rated for continuous operation from –40°C to +110°C case temperature. Its thermal design supports conduction-cooled industrial enclosures and fanless deployments. Derating guidelines in the datasheet specify junction-to-case thermal resistance (θJC) of 0.35°C/W, enabling reliable operation at full performance up to 110°C with appropriate PCB copper pour and thermal vias.
Is PCIe 3.0 support mandatory for host communication with the VSC7558TSN-V/5CC?
No, PCIe 3.0 is optional but recommended for high-bandwidth host interfaces. The VSC7558TSN-V/5CC also supports PCIe 2.0 and offers alternative host interfaces including SPI, JTAG, and GPIO-based UART. However, PCIe 3.0 x4 is required to sustain full control-plane throughput when managing >16 ports with real-time telemetry and TSN configuration updates.
