In a significant leap forward for smart home usability, STMicroelectronics (ST), a global semiconductor leader, has announced the industry-first secure NFC chip designed for the latest Matter 1.5 specification. The new ST25DA-C chip enables a groundbreaking "tap-to-go" device onboarding experience, promising to make adding smart devices to a home network as effortless as making a contactless mobile payment.
This innovation addresses a core challenge in the smart home market: complex and fragmented setup processes. The ST25DA-C is poised to dismantle this barrier, ushering in an era of unprecedented simplicity, security, and interoperability for consumers and manufacturers alike.
The Matter Standard and the NFC Revolution
Matter is the unifying, open-source application-layer standard developed by the Connectivity Standards Alliance (CSA). Its primary goal is to ensure reliable, secure connectivity across smart home devices, ecosystems, and brands. The recently released Matter 1.5 update introduces a pivotal enhancement: standardized NFC-based device commissioning.
This is where STMicroelectronics' ST25DA-C makes its mark as a pioneering commercial solution. It is the first chip of its kind to fully support this new NFC provisioning feature within the Matter framework. Instead of navigating smartphone apps, scanning QR codes, or dealing with Bluetooth pairing, users can now tap their NFC-enabled smartphone to a compatible smart light, lock, camera, or sensor. In one seamless step, the device is securely authenticated, configured, and added to the home network.
Simplifying the Smart Home
David Richetto, Executive Vice President and General Manager of the Secure Connected Connectivity Division at STMicroelectronics, emphasized the transformative potential of this technology. "The integration of NFC-based onboarding in Matter 1.5 is a timely enhancement to the smart home experience," said Richetto. "Our market-first ST25DA-C chip leverages this capability to simplify device commissioning through tap-to-pair functionality. This reduces setup complexity, especially for installations that are difficult to access."
He further highlighted a critical technical advantage: "Thanks to NFC-enabled battery-less connectivity. This aligns well with the broader momentum in the smart home market to serve consumers who increasingly prioritize ease of use, interoperability, and security. NFC-enabled Matter devices are positioned to play a key role in driving even greater adoption."
Unpacking the Technical Advantages of the ST25DA-C
1. Unmatched Ease of Use:
The ST25DA-C is fully compliant with the NFC Forum Type 4 Tag standard, leveraging the ubiquitous NFC support in modern smartphones. Compared to traditional methods like Bluetooth or QR codes, NFC provisioning is faster, more reliable, and inherently more secure. It also works in scenarios where other methods fail—for instance, when a device lacks a display for a QR code or is in a low-power state.
A key innovation is its passive operational capability. The ST25DA-C security NFC tag harvests energy from the smartphone's RF field to power the cryptographic operations required for Matter device commissioning. This means devices can be onboarded instantly upon unboxing, even before their main battery is charged or they are plugged in, dramatically simplifying multi-device setup.
2. Foundation of Trust and Security:
Security is non-negotiable in the connected home. The ST25DA-C is built upon ST's proven, market-tested embedded asset security technology. It provides robust protection through:
Secure storage for cryptographic keys, certificates, and network credentials.
Device authentication to prevent impersonation and unauthorized access.
A hardware platform based on a Common Criteria certified design, targeting GlobalPlatform IoT Platform Security Evaluation Standard (SESIP Level 3) certification. This ensures the chip meets rigorous, internationally recognized security benchmarks for IoT applications.
Market Validation and Future Outlook
Industry analysts recognize the strategic importance of this development. Shobhit Srivastava, Senior Principal Analyst at Omdia, commented, "Matter is an important standard for the smart-home industry, enabling seamless communication across devices, mobile apps, and cloud services. Its primary benefit is simplifying technology for non-expert consumers, which could help accelerate the adoption of connected devices. The new STMicroelectronics' ST25DA-C secure NFC chip is one example of a next-generation chipset that supports this standard, providing device makers with tools to develop the next generation of smart-home products."
The introduction of NFC touch-to-connect via chips like the ST25DA-C is more than a convenience feature; it is a catalyst for mass market adoption. By reducing setup friction to near zero, it lowers the technical barrier for all users, making advanced smart home technology accessible to a broader audience.
Availability and Next Steps
The ST25DA-C is currently available in a miniature DFN8 package for customer evaluation. Mass production is planned to commence in 2026. Device manufacturers interested in pioneering next-generation, easy-to-commission Matter products can contact their local STMicroelectronics sales office for detailed documentation, engineering samples, and evaluation kits.
Conclusion
STMicroelectronics ST25DA-C is a key that unlocks the full, user-friendly potential of the Matter standard. By enabling the secure, one-touch onboarding envisioned in Matter 1.5, it solves a longstanding pain point for consumers and provides manufacturers with a trusted, standardized solution to build upon. As the smart home market continues to evolve, the ST25DA-C stands as a foundational component for a future where connectivity is reliable, secure, and seamless to use.
