Available as 8-inch wafer with gold bumps (75 µm or 120 µm thickness, 50 pF capacitance), it supports 106 kbit/s data transfer at 13.56 MHz per ISO/IEC 14443-A and provides tearing-proof write operations for lock bits and capability container, making it ideal for smart packaging and brand protection applications requiring tamper evidence.","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 NTAG213 TagTamper NFC chip with integrated tamper-detection loop, 144 bytes user memory, ECC originality signature, and tamper event logging for brand protection.","faq":[{"a":"The NTAG213 TagTamper (NT2H1311TT) is designed for brand protection and smart packaging applications requiring tamper evidence. It detects the status of a connected tamper wire (open/closed) during startup and permanently stores tamper events, making it ideal for detecting product opening or seal breaking.","q":"What is the NTAG213 TagTamper used for?"},{"a":"The chip features an integrated tag tamper detection loop that monitors a connected tamper wire. During startup, it detects whether the wire is open or closed and permanently stores any tamper events in memory. This provides irreversible evidence if a seal or package has been opened.","q":"How does the NTAG213 TT tamper detection work?"},{"a":"The NTAG213 TagTamper has 144 bytes of user-accessible memory and 184 bytes total memory, organized as 46 pages of 4 bytes each. This is the same user memory capacity as the standard NTAG213.","q":"How much memory does the NTAG213 TagTamper have?"},{"a":"The chip offers ECC-based originality signature using secp128r1 curve (customizable and lockable), 32-bit password protection with PACK acknowledge, configurable authentication attempt limits (AUTHLIM), field-programmable read-only locking, and tamper detection. These features enable both product authentication and tamper evidence.","q":"What security features does the NT2H1311TT provide?"},{"a":"Yes, as an NFC Forum Type 2 Tag compliant with ISO/IEC 14443-A, the NTAG213 TagTamper is compatible with all NFC-enabled smartphones and devices. It operates at 13.56 MHz with 106 kbit/s data transfer rate.","q":"Is the NTAG213 TagTamper compatible with all NFC phones?"},{"a":"The NTAG213 TT (TagTamper) adds integrated tamper-detection functionality with a dedicated tamper wire loop and permanent tamper event logging, while maintaining the same 144-byte user memory and security features as the standard NTAG213. It is specifically designed for applications requiring physical tamper evidence.","q":"What is the difference between NTAG213 and NTAG213 TT?"}],"standards":["iso-14443a","nfc-forum-type-2"],"alternatives":["a48c6850-32cf-4cbd-b7cc-e06b7b911944","4191c449-4d3a-4e71-bc62-52f78fbdc2d0","0276ee78-144a-43f3-a532-5c4efa22fe8b"],"no_direct_competitor":false,"long_form_html":null,"og_image_url":null,"canonical_url":"https://rfid-datasheet.com/chip/ntag213-tagtamper"}}
