Product details
Overview
NT4H2421G0DA8/02J from NXP Semiconductors is a secure NFC Forum Type 4 Tag IC with AES-128 cryptography, Secure Unique NFC (SUN) message generation, and 416-byte file-based memory (256-byte NDEF + 128-byte proprietary file). It operates at 13.56 MHz, supports up to 848 kbit/s data rates, and features 50 pF input capacitance for compact antenna integration - deployed in anti-counterfeiting labels, secure loyalty tags, and authenticated packaging.
For engineers reviewing the NT4H2421G0DA8/02J datasheet, NT4H2421G0DA8/02J pinout, NT4H2421G0DA8/02J application, or NT4H2421G0DA8/02J equivalent, key selection considerations include SUN authentication support, ISO/IEC 7816-4 file access control per EF, LRP-wrapped AES side-channel resistance, 200,000 write endurance, and MOA8/SOT500-4 module-level packaging for surface-mount embedding.
Technical Context
The NT4H2421G0DA8/02J implements a full ISO/IEC 14443-4 PICC Type A stack with ATS negotiation, PPS-supported speeds up to 848 kbit/s, and dual-mode UID handling (7-byte fixed or 4-byte Random ID). Its on-die analog front-end includes a 50 pF resonance capacitor and rectifier optimized for low-power, high-coupling operation across small-form-factor antennas.
Security processing is partitioned across dedicated co-processors: AES-128 engine with LRP wrapper for side-channel resilience, TRNG for SUN nonce generation, and MMU-enforced file-level access control. Memory management follows ISO/IEC 7816-4 with three static Elementary Files (CC, NDEF, Proprietary), each configurable with independent read/write/change rights tied to five customer-defined AES keys and versioned key management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar secure NFC tag applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NT4H2421G0DUD/02 | Same die, FFC wafer format (120 μm thickness, Au bumps); no integrated module - requires external antenna design and flip-chip assembly | Suitable for ultra-thin label or inlay manufacturing where MOA8's SOT500-4 footprint is incompatible | Select when optimizing for minimal z-height or custom antenna integration; not drop-in compatible with MOA8 land pattern |
| NT4H2421GCDA8/02 | Identical MOA8/SOT500-4 package and pinout; pre-configured as customer-configurable version with unlocked keys and factory-default access settings | Targeted for OEMs requiring full key personalization and custom file permissions - differs from NT4H2421G0DA8/02J's locked default configuration | Select when full control over AES key provisioning and file-level access policy is required during production programming |
Compared with NT4H2421G0DA8/02J, NT4H2421G0DUD/02 demands custom antenna implementation but offers thinner profile, while NT4H2421GCDA8/02 provides identical mechanical fit with open key management - making NT4H2421G0DA8/02J optimal for turnkey secure tagging with pre-validated defaults.

FAQ
What security certifications apply to the NT4H2421G0DA8/02J?
The NT4H2421G0DA8/02J holds Common Criteria EAL4 certification for both hardware and software, validating its resistance to physical and logical attacks. It implements NIST SP 800-38A/B-compliant AES-128, LRP-wrapped cryptography for side-channel mitigation, and ECC-based NXP originality signatures - all confirmed in the official NXP product data sheet Rev. 3.0.
Does the NT4H2421G0DA8/02J support iOS and Android without custom apps?
Yes - the NT4H2421G0DA8/02J SUN authentication mechanism works natively on Android devices without dedicated apps, and on iOS 11+ when paired with an approved app that handles the SUN message verification flow. This cross-platform interoperability is enabled by ISO/IEC 7816-4 command framing and standardized NDEF mirroring behavior.
What is the function of the two pins (LA and LB) on the NT4H2421G0DA8/02J MOA8 package?
LA and LB are the differential antenna connection terminals of the NT4H2421G0DA8/02J. They interface directly with a printed loop antenna to form a resonant LC circuit using the IC's internal 50 pF capacitance. No external matching components are needed - LA and LB must be connected symmetrically to ensure optimal power harvesting and communication range up to 10 cm.
Can the NT4H2421G0DA8/02J be used for encrypted data storage beyond the NDEF file?
Yes - the NT4H2421G0DA8/02J includes a dedicated 128-byte proprietary file (EF 03h) configured by default in Full Protection mode. This file supports AES-128 encrypted reads/writes using any of the five customer-defined keys, enabling secure storage of credentials, calibration data, or firmware fragments inaccessible without authenticated session.
How does the Random ID feature enhance privacy in the NT4H2421G0DA8/02J?
The NT4H2421G0DA8/02J supports configurable Random ID (RID), replacing the fixed 7-byte UID with a 4-byte dynamically generated identifier. When enabled, RID prevents long-term device tracking across scans - and combined with encrypted UID mirroring in the NDEF file, it satisfies GDPR and CCPA requirements for anonymized user interaction logging.
