Onsemi announced the new 10BASE-T1S Ethernet controller NCN26010 on the 22nd. It is designed to provide reliable multipoint communication in industrial environments.

ON Semi explained that the NCN26010 simplifies installation and achieves greater data throughput. It stated that by enabling the use of more than 40 nodes on a single twisted pair, it reduces installation costs and configuration complexity, noting that this number of nodes exceeds five times the number of nodes required by the IEEE 802.3cg standard.

For wiring within the cabinet, the NCN26010 reduces wiring by up to 70% while significantly increasing bandwidth, and simplifies layout and power distribution in the backplane without affecting data rates or latency. In addition, many applications, such as elevators, can increase data throughput compared to conventional wiring, and complex sensor networks can be built based on simple and inexpensive cable operation due to the power transmission capability through data cables.

The new controller implements multi-drop 10BASE-T1S (802.3cg) Ethernet, which effectively replaces existing point-to-point and multipoint industrial communication standards. Here, the T1S MAC/PHY can replace RS-485, CAN, RS-232, HART, etc. As a result, data throughput is improved compared to existing wiring, eliminating the need to rewire, which accounts for the largest cost in networking installations.

Controller-based single-pair Ethernet installations reduce the number, volume, and cost of wiring, while multi-drop functionality allows multiple nodes, such as sensors, to be connected to a single twisted pair. Additionally, the NCN26010 features enhanced noise immunity, which is essential for installations in industrial environments with severe electrical noise.

In addition, the NCN26010 has lower line pin capacitance than existing T1S solutions, allowing for the implementation of more nodes in a single network. Since communication with the NCN26010 is performed via SPI, it has a small pin count and a compact package size. The NCN26010 is a PHY + MAC controller for 10BASE-T1S and can be connected to controllers, sensors, and other devices without an external MAC.

Michel de May, Vice President of Industrial Solutions at Onsemi, stated, "The NCN26010 enables large multi-drop networks, reducing the total number of networks required for large-scale installations," adding, "Customers can benefit from the fact that our fully integrated solution is smaller and easier to integrate than previous controllers."
