How built-in security simplifies design
The ST25DA-C supports all the algorithms and cryptographic operations required by CSA/Matter standard.
Built on ST expertise in secure devices, the ST25DA-C ensures fully interoperable and secure commissioning of any Matter devices. It stores and protects sensitive data (such as private keys and network credentials) within its embedded secure element. This removes the need for separate secure storage or a secure MCU.
Housed in a compact 2 x 3 mm package, and combined with a tiny antenna, this tag is optimized for small smart home devices.
