Transportation systems make up the backbone of worldwide commerce moving people and products via roadways, waterways, railways, and airways. Key to transportation system development is the need to meet industry standards, address safety requirements, and continually improve efficiencies while maintaining system compatibility.

Most transportation systems are based on large complex electromechanical units connected by an array of control and communication units. Because many systems transport people or hazardous materials, safety and reliability become a primary goal. Based on the high cost and infrastructure investments required, as a result, these systems need to be designed for long life cycles.

Supply chain management within the transportation industry needs to closely align its requirements with the semiconductor supply chain. Like the automotive market, an increasing amount of automation and technology is built into each system. This brings significant improvement in performance, efficiency, and safety. However, this technology can adversely impact existing systems and infrastructure support.

The semiconductor industry continually evolves shifting device geometries, package technologies, and power requirements. System-level enhancements to interface protocols and processor architectures result in even more changes. While these modifications provide benefits to new systems, existing systems are challenged with sustaining lifecycles which, in many cases, are measured in decades.

Rochester Electronics' focus on providing a continuous source of semiconductors aligns strongly with the long lifecycle requirements of equipment manufacturers. Rochester provides 100% authorized stock of active and end-of-life (EOL) devices from over 70 leading semiconductor manufacturers. As a licensed semiconductor manufacturer, Rochester has manufactured over 20,000 device types. With over 12 billion die in stock, Rochester has the capability to manufacture over 70,000 device types.
