产品概述
描述
The ST25DA-C device is an NFC dynamic tag integrated circuit providing the upcoming Matter commissioning flow over NFC, and cryptographic services.
The ST25DA-C offers a solution for commissioning a new device on a Matter network without requiring external power. On the NFC interface, it offers NFC Forum T4A Tag and Matter NFC Transport Layer applications. It implements secure storage, cryptographic primitives, and protocols to handle Matter Passcode-Authenticated Session Establishment (PASE) based on SPAKE2+ protocol, authentication of Matter device conformance with Matter device attestation, Node Operational Certificate (NOC), offline configuration of the operational network (Thread), and online signature service required for Certificate-Authenticated Session Establishment (CASE).
Based on a Common Criteria (CC) certified secure hardware, the device is designed to be the NFC component of a smart IoT device, acting as an NFC secure companion to the main microcontroller.
It exposes an NFC Forum Type 4 interface to communicate with a smartphone, and a high-speed (400 kHz) I²C interface to communicate with the main microcontroller.
