Switching ASIC for Industrial Network Switches

Product Specifications

Technical details and manufacturing context for Switching ASIC

Definition

A Switching ASIC (Application-Specific Integrated Circuit) is a specialized semiconductor component within an Industrial Network Switch that performs high-speed data packet processing, forwarding decisions, and traffic management. It implements switching logic, MAC address learning, VLAN tagging, QoS prioritization, and other networking protocols at hardware level for deterministic performance in industrial environments. The ASIC is fabricated on a silicon wafer with copper interconnects and dielectric materials, using process nodes ranging from 7 to 16 nm. It is packaged in a flip-chip ball grid array (FCBGA-2560) and operates over a supply voltage of 0.9–1.8 V. Key parameters include switching capacity of 1.28–51.2 Tbps, packet forwarding rate of 1.9–76.4 Bpps, port density of 32–128 ports, SerDes data rate of 25.6–112 Gbps, packet buffer size of 32–512 MB, latency of 300–900 ns for 64-byte packets, power consumption of 75–350 W, operating temperature range of -40 to 85°C (industrial grade; commercial grade is 0–70°C), and reliability (MTBF) of 1,000,000–5,000,000 hours. These values are directory reference ranges and must be confirmed for the specific model and application with the legal manufacturer or supplier. The ASIC is designed for use in industrial network switches, providing deterministic performance for critical automation and control systems.

Working Principle

The Switching ASIC receives data packets through physical ports, parses packet headers, makes forwarding decisions based on MAC address tables and VLAN configurations, applies QoS policies, and directs packets to appropriate output ports. It operates at wire speed using dedicated hardware logic rather than software processing. The ASIC uses high-speed SerDes interfaces to connect to physical ports, and its internal packet buffer manages bursts and congestion. The forwarding decisions are made in hardware, ensuring low and predictable latency. The ASIC also supports features like VLAN tagging and QoS prioritization, which are essential for industrial networks. The exact implementation details vary by model, and verification with the manufacturer is recommended.
