STMicroelectronics ST25TN01K-AFH5 RF Transceiver IC, 5-Pin DFN-5

The STMicroelectronics NFC forum type 2 tag IC is provided 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 RF field provided by the NFC poller, it simply operates with an antenna and without additional component. The embedded electrically erasable programmable memory (EEPROM) can be written with a NDEF message conforming to NFC Forum specification offering native tap with all NFC-enabled phones.
