ST ST25DA-C is an NFC chip with built-in support for the latest Matter 1.5 protocol, enabling easier installation of smart devices on home networks, including lighting, access control, security cameras, or any IoT device. NFC here is used as an alternative to Bluetooth LE or QR core commissioning. NFC tap-to-pair functionality enables users to tap an NFC tag code on a device with their smartphone to securely and easily add it to their Matter-compatible app(s) and network(s). Besides batteryless commissioning, the ST25DA-C chip can also be used for firmware updates over I2C (Matter OTA), and secure storage for keys & certificates. ST25DA-C secure NFC tag specifications: Contact interface 1.62 V to 3.3 V supply voltage range ESD protection Human body model (HBM): 6 kV for digital and antenna pads Charge device model (CDM): 1 kV based on a STMicroelectronics module I2C serial interface up to 400 kHz Contactless interface Power […]
