They feature an innovative field-detection pin with configurable triggers (RF presence, start-of-frame, or tag selection) enabling microcontroller wake-up, plus a SLEEP mode for privacy control. Additional features include FAST_READ command for reduced overhead, ECC-based originality signature for authentication, ASCII mirroring of UID and NFC counter for dynamic NDEF messages, and 32-bit password protection with optional attempt limiting. The HXSON4 package maintains pin compatibility with NTAG203F while offering 50 pF input capacitance and 106 kbit/s data rate.","enriched":true,"url_status":"ok","link_status":"valid","last_checked":"2026-11-01T03:31:28.371+00:00","last_status_code":200,"last_content_type":"application/pdf","created_at":"2026-06-14T16:30:56.111445+00:00","manufacturer_id":"6daaf1cc-d0e6-40c7-aba0-a08b4c3493fe","chip_type":"tag_ic","dual_interface":false,"is_family_hub":false,"meta_description":"NXP NTAG213F/216F NFC Forum Type 2 tag ICs with field-detection pin, 144/888 bytes user memory, ECC originality signature, and password protection for secure brand authentication.","faq":[{"a":"NTAG213F provides 144 bytes of user memory (180 bytes total), while NTAG216F offers 888 bytes of user memory (924 bytes total).

It enables microcontroller wake-up in battery-powered applications, reducing power consumption when no NFC field is present.","q":"What is the field detection pin on NTAG213F and NTAG216F used for?"},{"a":"The NTAG213F and 216F include an ECC-based cryptographic signature that enables authentication of tag genuineness. This feature helps protect against counterfeiting in brand protection applications by allowing verification that the tag is an original NXP product.","q":"How does ECC-based originality signature work on NTAG21xF chips?"},{"a":"Yes, both NTAG213F and 216F feature 32-bit password protection with configurable access control. The password can include optional attempt limiting to prevent brute-force attacks, and supports read/write access restrictions.","q":"Does NTAG216F support password protection?"},{"a":"SLEEP mode is a privacy feature that allows the tag to be temporarily disabled and unresponsive to reader commands. This prevents unauthorized scanning until the tag is reactivated, providing user control over data accessibility.","q":"What is the SLEEP mode on NTAG213F and NTAG216F?"},{"a":"Yes, both NTAG213F and 216F support ASCII mirroring of the 7-byte UID and NFC read counter into user memory.
