ON Semiconductor has announced a new 10BASE-T1S Ethernet controller designed to provide reliable multipoint communications for industrial environments. The NCN26010 simplifies installation, enables greater data throughput, and enables more than 40 nodes on a single twisted pair, exceeding five times the number of nodes required by the IEEE 802.3cg standard, reducing installation cost and setup complexity.
For in-cabinet cabling, the NCN26010 reduces cabling by up to 70% while significantly increasing bandwidth. In the backplane, it simplifies layout and power distribution without compromising data rates or latency. With the new device, many applications such as elevators will be able to increase data throughput over existing wiring, and complex sensor networks can be built with simple and low-cost cabling due to the ability to transmit power over data cables.
Michel De Mey, Vice President of ON Semiconductor's Industrial Solutions Division, said: "The NCN26010 enables larger multi-site connected networks, reducing the total number of networks in large installations. Customers adopt our new fully integrated controller solution, which is more The device is smaller and easier to integrate.”
The new controller implements multi-drop connection communication 10BASE-T1S (802.3cg) Ethernet, effectively replacing the traditional point-to-point and multi-point on the same bus (multi-point) industrial communication standard. T1S MAC/PHY replaces standards such as RS-485, CAN, RS-232 and HART. As a result, greater data throughput is achieved on existing cabling without the need for re-wiring, saving the largest expense in network installations.
A single-pair Ethernet installation based on the controller reduces the amount, size and cost of wiring, while the multi-drop capability allows multiple nodes, such as sensors, to be connected to a single twisted pair. The NCN26010 also includes proprietary enhanced noise immunity, which is critical for installations in electrically noisy industrial environments.
In addition, the NCN26010 has lower capacitance on the line pins than existing T1S schemes, enabling more nodes to be implemented on a single network. Since communication with the NCN26010 can be via SPI, there are fewer pins and a smaller package size. The NCN26010 is the industry's first 10BASE-T1S capable PHY + MAC controller that can be connected to controllers, sensors and other devices without the need for an external MAC.
