Overview
The STF203 is a combination EMI filter and line termination device with integrated TVS diodes for use on upstream USB ports. It is constructed using a proprietary technology that allows passive components and TVS diodes to be integrated in the same package. Each device will provide termination, filtering, and ESD protection for one upstream USB port. The STF203 is an easily implemented solution for meeting the requirements of revision 1.1 of the Universal Serial Bus specification. Line termination is achieved with series resistors on both the D+ and D- USB lines. The STF203 has resistor values of 15/22/33Ω. The 1.5kΩ pull-up resistor is required by the USB specification to identify the equipment as either a full-speed or low-speed device. The 47pF capacitors are required to bypass high frequency energy to ground and to control the edge rate of the USB signals. The TVS diodes provide ESD protection of both (D+ and D-) data lines and the voltage bus (VBUS).

Buildings are among the world's largest consumers of energy and one of their most underleveraged sources of operational intelligence. According to the International Energy Agency, the building sector accounts for roughly 30% of global final energy consumption and nearly 26% of global energy-related emissions. Yet the vast majority of the world's existing building stock — the millions of offices, hospitals, factories, warehouses, schools, and retail spaces that people occupy every day — remains largely unconnected. Heating runs on fixed schedules rather than occupancy. Leaks go undetected for weeks. Equipment fails without warning. Space sits unused while teams compete for meeting rooms.

When evaluating low-power wide-area network (LPWAN) technologies for internet of things (IoT) deployments, security is no longer a checkbox, it's a fundamental design requirement. As regulations tighten and cyber threats grow more sophisticated, the question isn't just "does this technology work?" but "can I trust it with my data, my devices, and my compliance obligations?"
The answer for LoRaWAN® is a confident yes and here's why.

The fourth generation of LoRa® technology is revolutionizing edge intelligence with breakthrough capabilities
The Internet of Things (IoT) landscape is undergoing a fundamental transformation. As artificial intelligence (AI) and machine learning (ML) move from the cloud to the edge, IoT devices face an unprecedented challenge: how to support intelligent applications that require higher data throughput while maintaining the long battery life and extended range that make wireless sensors practical in the first place.
Shahar Feldman, senior product marketing director for LoRa integrated circuits (ICs) at Semtech, recently presented how the company's new LoRa Plus™ technology addresses this critical challenge head-on, ushering in a new era of AI-enabled IoT deployments.

Embedded World 2026, one of Europe's most anticipated technology events, brought together thousands of engineers, innovators and decision-makers at Messe Nuremberg from March 10 to 12. If there was one theme that defined the event, it was Edge AI. The story everywhere you looked was the same: intelligence at the edge, processing closer to the source and only essential data making its way to the cloud. And right at the heart of that story was LoRa®technology.
