Ethernet controller provides reduced wiring and costs

Mouser Electronics now stocks the NCN26010 Industrial Ethernet Controller from onsemi. This 10BASE-T1S Ethernet controller is designed to provide reliable multi-point communication in industrial settings.

The device is a 10Mb/s, IEEE 802.3cg compliant device, including a MAC, a PLCA reconciliation sublayer, and a 10BASE-T1S PHY, created for industrial multi-drop Ethernet networks. The device can allow more than 40 nodes on a single twisted pair, exceeding five times the number of nodes asked by the IEEE 802.3cg standard, decreasing installation cost and set-up complexity. This PHY + MAC controller for 10BASE-T1S can connect to controllers, sensors and other devices without needing an external MAC.

The controller decreases in-cabinet wiring by up to 70% while greatly increasing bandwidth. In backplanes, it simplifies the layout and power distribution without impacting data rates or latencies. Many applications, such as elevators, can increase data throughput over existing wiring with the device and due to the ability to carry power across data cables, complex sensor networks can be built upon simple and low-cost cable runs.

The device makes an ideal replacement for legacy point-to-point and multi-point industrial communication standards. The T1S MAC/PHY device can replace RS-485, CAN, RS-232, HART and others. As a result, greater data throughput is accomplished over existing wiring, eradicating the need to re-pull wires which is often the most significant expense in a networking installation. The controller also provides a proprietary enhanced noise immunity feature essential for installations in electrically noisy industrial environments.

The NCN26010XMNEVB 10BASE-T1S MACPHY evaluation board supports the controller, the NCN26010BMNEVB Adapter Board, and the NCN26010XMNEVK 10BASE-T1S SPE evaluation kit, all available from Mouser.
