STMicroelectronics (ST) said on the 8th that it has released the ST25DA-C, an NFC chip based on the Matter smart home standard.
As the industry's first Trusted Platform Module (TPM) supporting the Matter 1.5 specification, it allows smart home devices such as lighting, access control, and security cameras to be registered to a home network instantly with a single smartphone tap.
Through NFC-based onboarding, the ST25DA-C supports faster and more reliable device registration than existing Bluetooth or QR code methods. Using RF field Energy Harvesting, it performs cryptographic operations without power, enabling device additions even in installation environments without batteries or with difficult access, and it also streamlines the parallel registration of multiple accessories.
It integrates a Common Criteria-certified hardware-based secure storage to strengthen smart home security elements such as device authentication, cryptographic keys, and certificates, and supports achieving GlobalPlatform SESIP Level 3 certification.
ST will provide evaluation and sampling based on a DFN8 package and plans to begin mass production in 2026. Related technical documents and evaluation kits can be obtained through ST's Korea office.
David Richetto, executive vice president and head of ST's Connected Security Product Group, said, "By integrating NFC-based onboarding into Matter 1.5, the smart home user experience is further improved," and noted, "It aligns with market trends that value ease of use, interoperability, and security."
