STMicroelectronics ST25TN01K NFC Forum Type 2 Tag IC

STMicroelectronics ST25TN01K NFC Forum Type 2 Tag IC is an NFC Forum Type 2 Tag IC with TruST25 digital signature, Augmented NDEF, and privacy features. The RF interface is compliant with ISO/IEC 14443-2 and 14443-3 Type-A standards, and NFC Forum Type 2 tag specification. Thanks to its internal tuning capacitance and harvesting of operating power from the RF field provided by the NFC poller, it simply operates with an antenna and without additional components.
