Product details
Overview
NT4H2421G0DUD/02V from NXP Semiconductors is a secure NFC Forum Type 4 Tag IC implementing ISO/IEC 14443-4 and ISO/IEC 7816-4, featuring AES-128 cryptography, 416-byte file-based memory (256-byte NDEF + 128-byte proprietary file), 50 pF input capacitance, and Secure Unique NFC (SUN) message generation for tap-unique authentication in anti-counterfeiting and brand protection systems.
For engineers reviewing the NT4H2421G0DUD/02V datasheet, NT4H2421G0DUD/02V pinout, NT4H2421G0DUD/02V application, or NT4H2421G0DUD/02V equivalent, key selection considerations include SUN message integrity, configurable per-file access control with five AES keys, LRP-wrapped AES side-channel resistance, 10 cm read range, and MOA8/SOT500-4 module compatibility.
Technical Context
The NT4H2421G0DUD/02V implements a dual-layer security architecture: hardware-level LRP-wrapped AES-128 for side-channel attack resilience and software-level Secure Dynamic Messaging (SDM) enabling SUN message mirroring into NDEF. It supports full ISO/IEC 14443-4 A-type protocol stack including PPS negotiation up to 848 kbit/s and cascade-level UID handling with ATQA 0344h (7-byte UID) or 0304h (4-byte Random ID).
Its memory controller enforces file-level communication modes-Plain, MAC-protected, or Full Enciphered-and integrates a dedicated MMU with configurable access rights per Elementary File (EF), where EF01 (CC), EF02 (NDEF), and EF03 (proprietary) each support independent Read/Write/ReadWrite/Change permissions tied to specific AppKeys or free access.

FAQ
What security certifications apply to the NT4H2421G0DUD/02V?
The NT4H2421G0DUD/02V holds Common Criteria EAL4 certification for both hardware and software, validating its resistance to physical and logical attacks. It complies with NFC Forum Type 4 Tag specification (Certification ID: 58562), ISO/IEC 14443-4, and ISO/IEC 7816-4. Its LRP-wrapped AES implementation meets NIST SP 800-38A/B standards for cryptographic robustness - all confirmed in the official NXP product data sheet Rev. 3.0.
How does the Secure Unique NFC (SUN) feature work on the NT4H2421G0DUD/02V?
The NT4H2421G0DUD/02V generates a SUN message on every tap using AES-128 and internal counters, producing a cryptographically unique payload that includes integrity protection and confidentiality. This message is mirrored in ASCII format within the NDEF record and verified by a backend server - working natively on Android and with minimal app support on iOS11+. The mechanism is guaranteed by the chip's Secure Dynamic Messaging engine and requires no persistent connection to function.
What is the memory organization of the NT4H2421G0DUD/02V?
The NT4H2421G0DUD/02V implements a strict ISO/IEC 7816-4 file system with 416 bytes total: a 32-byte Capability Container (EF01), a 256-byte NDEF file (EF02), and a 128-byte proprietary file (EF03). Each file supports independent access control via five configurable AES keys, and default communication modes are Plain for EF01/EF02 and Full Enciphered for EF03 - ensuring sensitive data remains encrypted during transmission.
Can the NT4H2421G0DUD/02V operate with small antennas?
Yes - the NT4H2421G0DUD/02V features a high 50 pF input capacitance, allowing reliable operation with compact loop antennas down to 15 mm². This enables embedding in constrained spaces like bottle caps, pharmaceutical blister packs, and thin-film labels while maintaining up to 10 cm read distance under standard field conditions - a key advantage over earlier NTAG generations with lower Ci values.
What are the supported communication speeds for the NT4H2421G0DUD/02V?
The NT4H2421G0DUD/02V supports all standard NFC data rates: 106 kbit/s, 212 kbit/s, 424 kbit/s, and 848 kbit/s. It negotiates speed via PPS (Protocol and Parameter Selection) after ATS exchange per ISO/IEC 14443-4, with TA(1) = 0x77 indicating bidirectional support for 212–848 kbit/s. Performance is validated across commercial readers including ACS ACR1252U and Feitian SCL3711.
