STMicroelectronics Unveils Secure One-Tap NFC Chip

STMicroelectronics has introduced the ST25DA-C, the industry’s first NFC chip fully compatible with Matter 1.5, the latest smart-home connectivity standard. Designed to streamline smart-home device setup, the new chip enables users to connect devices to a Matter-based network with just a single tap, eliminating the need for complex pairing or QR code scanning.

This innovation positions STMicroelectronics at the forefront of smart-home semiconductors and addresses growing consumer demand for faster, more intuitive home automation solutions.

One-Tap NFC Setup for Hassle-Free Integration

The ST25DA-C allows devices such as lights, thermostats, smart locks, and sensors to join Matter networks effortlessly. Users simply tap their NFC-enabled smartphone on the device to complete the onboarding process.

Benefits include:

• Simplified setup without scanning QR codes or using Bluetooth pairing

• Faster installation for multiple devices at once

• Convenience for hard-to-reach or powered-off devices, as the chip can harvest energy from the NFC field

Secure, Energy-Efficient Commissioning

STMicroelectronics’ new NFC chip incorporates robust cryptographic functions, securely storing authentication credentials, certificates, and network keys required by Matter.

Moreover, the chip supports energy harvesting, enabling unpowered devices to join the network without requiring an external battery during setup. This feature ensures both security and efficiency, making it ideal for modern smart-home deployments.

Matter Standard: Driving Interoperability Across Smart Homes

Matter, developed by the Connectivity Standards Alliance (CSA), is an open-source, royalty-free smart-home standard supported by major tech companies including Apple, Google, and Amazon.

By supporting Matter 1.5, the ST25DA-C ensures:

• Seamless interoperability across multiple brands and devices

• Reliable, secure communications between smart-home devices

• Future-proofing for evolving IoT ecosystems

Why This Matters for Consumers and Manufacturers

The ST25DA-C addresses one of the biggest pain points in smart-home technology: complex setup processes. By offering a secure, intuitive, and energy-efficient solution, STMicroelectronics empowers manufacturers to deliver a better end-user experience, while driving adoption of open smart-home standards globally.
