Single Pair Ethernet for factory automation
SPE brings benefits to designers
The use of SPE reduces system cost, weight and wiring complexity. You can simplify many connectivity applications using SPE. When compared to proprietary or industry-specific protocols, Ethernet more readily supports the trend toward IP-based IoT edge computing.
Advantages of an SPE architecture include:
- A worldwide, open standards-based architecture that is vendor interoperable
- Use of the same protocol independent of physical layer (PHY) speed
- No need for gateways, resulting in seamless communication
- Well-understood, proven security infrastructure
- Authentication, encryption and secure updates
- Reduces verification and validation efforts, wiring cost, weight and installation complexity
- Large ecosystem of suppliers and applications
10BASE-T1S Technology
10BASE-T1S is the latest technology used to expand Ethernet to the edge of Operational Technology (OT) and Information Technology (IT) networks—even when your network consists of incompatible devices and different physical hardware. Much like its utility in other sectors, this technology also brings significant advantages to the automotive industry. Established by IEEE®, 10BASE-T1S technology provides a 10 Mbps, multidrop transmission medium that can include up to at least eight transceiver nodes. The transceiver nodes connect to a common mixing segment of up to at least 25m. According to the IEEE specification, these limits are actually “minimum maxima”; this makes it possible to use more than eight nodes and transmit over longer distances.
This technology enables standard Ethernet communication, eliminating the need for gateways to interconnect incompatible communication systems. 10BASE-T1S reduces total system cost by using a single pair of wires and a multidrop bus architecture. 10BASE-T1S also increases system scalability since several nodes can operate on the same bus line with high data throughput. This allows the system to require fewer switch ports, cables and switches.

Security for factory automation
The interconnected nature of automated systems and the increasing reliance on digital infrastructure have exposed manufacturing facilities to unprecedented cybersecurity challenges. The seamless communication between devices, the utilization of data analytics, and the interplay of software and hardware create copious opportunities for cyber-attacks. The potential consequences of a cyberattack on factory automation range from disrupted production lines and compromised product quality to data breaches and even physical safety risks.
In this evolving landscape, it is essential to understand the intricate interplay between factory automation and cybersecurity. This involves implementing robust security measures, such as hardware authentication, firewalls, encryption, access controls, and intrusion detection systems, to safeguard against unauthorized access and data breaches.
The ISA/IEC 62443 is the industry standard for cyber security standard in industrial applications. Microchip provides a portfolio of products to satisfy the ISA/IEC62443 standard, and our FAEs will help you select the optimum product(s) to secure your systems from Cyber threats.

OPC UA
What is OPC UA?
OPC Unified Architecture (OPC UA) is a cross-platform, open-source IEC 62541 standard for machine-to-machine communication. Intended for industrial automation, OPC UA simplifies industrial connectivity and integrates devices, automation systems and software applications using a secure and platform-independent standard.
OPC UA supports robust security and time synchronization features to securely connect remote edge devices and enable device diagnostics, asset management, monitoring, reporting and other applications.
To implement the OPC UA protocol, PolarFire SoC FPGAs use a client-server architecture where the client initiates data requests that are processed by the server. PolarFire SoC FPGAs can be configured as servers or as clients.

Ethernet switching
Factory automation brings a need to connect islands of coherent communication. These islands are often built around Time Sensitive Networking and shall require this in future as factories align towards the IEC60802 Industrial Networking Profile.
Microchip answers this requirement with platforms such as LAN9668 – supporting the required protocols and with a maintained software suite. This software portfolio continues to grow in stability and capabilities where customers enjoy enhancements to a quarterly release cadence.
The LAN9662 is the latest addition to the LA966x product family and includes two integrated 10/100/1000BASE-T PHYs and a 600 MHz ARM Cortex A7 CPU subsystem. The LAN9662 includes four ports in addition to an Industrial Ethernet (IE) protocol Real-Time Engine (RTE) suited for meshed and daisy-chained low latency operation.
PCIe Endpoints
Customers designing industrial compute platforms are finding their traditional interfaces are typically no longer available and must be reached via PCIe. Microchip solves this problem with their new range of PCIe switching devices with included End Points (EP). A highly integrated single device enables 2.5G Ethernet, 10G USB3.2Gen2, RS-232, RS-485 and traditional lower speed interfaces whilst also providing additional PCIe ports. Supported within QNX, Windows and Linux. Designers are using this to enable external connectivity through to embedded M.2 abstractions which accommodate LTE and 5G radios.
