NFC Chip for Energy Harvesting
SIC4310
NFC Forum Type 2 Tag IC with UART interface and 8 GPIOs
NFC Forum Type 2 Tag IC with UART Interface and Energy Harvesting Function. NFC Forum Type 2 tag ICs with a UART interface, facilitating data transfer between NFC devices and UART-connected devices such as MCUs. Additionally, It can harvest energy for peripheral circuits—up to 10mA from desktop RFID readers and up to 7mA from typical NFC phones. This energy-harvesting capability enables “batteryless” applications, allowing devices to operate instantly when an NFC device is tapped, even without an internal battery
NFC Chip for Web Authentication
NFC Forum Type 2 Tag IC for Item-Level Authentication. The SIC43S1 and SIC43NT are passive NFC Forum Type 2 tag ICs fully compliant with ISO14443A standards. The user memory of both chips supports NDEF updating that returns a new unique value with every tap, enabling app-less NFC authentication. For higher security, the SIC43S1 is equipped with an AES-128 encryption engine, designed for mutual authentication and encrypted communication schemes.
SIC43NT
NFC Forum Type 2 Tag IC with Secured Rolling-Code
NFC Forum Type 2 Tag IC featuring web-based authentication feature with secure rolling code and the RF detection pin (RFD).
SIC43S1
NFC Forum Type 2 Tag IC with AES-128 encryption
NFC Forum Type 2 tag configured to be compatible with the dynamic NDEF format. It is also equipped with AES-128 (Advanced Encryption Standard), which provides secure authentication and data encryption for high-security purposes.
