onsemi Accelerates Building Automation with Industry First Solutions for KNX and Power over Ethernet (PoE)

PHOENIX – June 7, 2022 – onsemi (Nasdaq: ON), a leader in intelligent power and sensing technologies, today announced the introduction of two complete system solutions supporting the most widely used building automation network protocols - Power over Ethernet (PoE) and KNX.

Easing the development of access and control panels, the NCN5140S is the first System-in-Package (SiP) certified with the KNX Association. The NCN5140S integrates all critical and certifiable elements of a KNX device, including a digital KNX transceiver, a 32-bit Arm® Cortex®-M0+ microcontroller with a pre-certified software stack, and system power DC/DC converters, into a single package. With its high degree of integration, the NCN5140S considerably reduces material costs and allows manufacturers to develop very slim and modern designs (<5 mm total depth).

Alongside the NCN5140S, onsemi has introduced a complete solution for ethernet-powered connected lighting. Unique to any other device on the market, the NCL31010 integrates an intelligent LED driver and PoE interface into a single package. This provides support for both the lighting and power delivery needs of fully connected and managed lighting systems.

“As building automation installations continue to gain greater momentum, the industry needs solutions that incorporate necessary functionality in a simple, compact package," said Michel De Mey, vice president of the Industrial Solutions Division, onsemi. “With our pre-certified KNX SiP and new intelligent LED driver, onsemi provides manufacturers with the latest technology and the head start they need to develop complex, full-scale automation systems in a shorter time."

KNX products must demonstrate compliance to supported protocols and profiles through the association’s certification program to ensure seamless connectivity. Because the NCN5140S platform is pre-certified, products based on the device inherit this compliance, and KNX certification testing is not necessary. All that is needed is a KNX declaration of product modification, eliminating the time and engineering efforts of a complete certification process.

The IEEE 802.3bt compliant NCL31010 can deliver over 90 Watts via PoE. An innovative application for this device, made possible by the highly efficient buck LED driver, is called Visible Light Communication (VLC).This involves modulating data directly onto the LED light, which remains imperceptible to the human eye, allowing it to broadcast data and function as a location beacon for use in indoor positioning systems.

The NCL31010 and the NCN5140S are available now through onsemi sales support and authorized distributors.
