NXP Semiconductors NT4H1321G0DUD/06BV

Overview

NT4H1321G0DUD/06BV from NXP is a secure NFC Forum Type 4 Tag compliant IC with 160-byte read/write memory, 13.56 MHz HF operation, cryptographic AES-128 authentication, and the SUN (Secure Unique NFC message) feature that generates a new authentication code on every tap - deployed in brand protection, event ticketing, and document authenticity verification.

For engineers reviewing the NT4H1321G0DUD/06BV datasheet, NT4H1321G0DUD/06BV pinout, NT4H1321G0DUD/06BV application, or NT4H1321G0DUD/06BV equivalent, key selection considerations include SUN-based tap-uniqueness, ECC-based 56-byte Originality Signature, ISO/IEC 14443-A compliance, tamper-resistant hardware, and support for mutual authentication and secure channel protocols.

Technical Context

The NT4H1321G0DUD/06BV implements an embedded AES-128 crypto engine and SUN mechanism tied to internal state counters and physical unclonable function (PUF)-derived entropy, ensuring each tap yields cryptographically distinct authentication data. It operates exclusively in passive mode under ISO/IEC 14443-A RF field coupling.

Its secure architecture includes dedicated hardware for ECC signature generation (NXP Originality Signature), UID-based anti-cloning, and memory access control with configurable read/write lock bits - all enforced within a tamper-resistant silicon substrate without external power or clock requirements.

FAQ

What security features distinguish NT4H1321G0DUD/06BV from standard NFC tags?

The NT4H1321G0DUD/06BV integrates SUN (Secure Unique NFC message), AES-128 cryptographic authentication, and a 56-byte ECC-based NXP Originality Signature - enabling per-tap uniqueness, tamper-resistant origin verification, and secure channel support. Unlike basic NFC tags, NT4H1321G0DUD/06BV provides cryptographic proof of physical presence and data integrity without requiring a dedicated mobile app.

Does NT4H1321G0DUD/06BV require external power or a microcontroller to operate?

No - NT4H1321G0DUD/06BV is a passive NFC tag powered entirely by the reader's RF field. It contains no battery, crystal oscillator, or external interface; all cryptographic operations execute autonomously within its secure silicon core upon inductive coupling at 13.56 MHz.

How does the SUN feature in NT4H1321G0DUD/06BV prevent replay attacks?

The SUN feature in NT4H1321G0DUD/06BV uses internal state counters and PUF-derived entropy to generate a cryptographically unique authentication code on every tap - ensuring no two responses are identical. This eliminates replay attacks because intercepted responses cannot be reused, even if captured during legitimate reads.

Can NT4H1321G0DUD/06BV be used for two-factor authentication in web logins?

Yes - NT4H1321G0DUD/06BV supports secure log-in credentials via one-time cryptographic codes stored or generated on-tag. When paired with compatible backend services, it enables tap-based second-factor verification for corporate portals, e-commerce, or email - leveraging its SUN and Originality Signature for strong binding to physical possession.

What is the memory structure of NT4H1321G0DUD/06BV and how is it protected?

NT4H1321G0DUD/06BV provides 160 bytes of user-accessible EEPROM organized in NDEF-compliant format, with configurable read/write lock bits and access conditions enforced by its secure controller. Memory contents remain cryptographically bound to the tag's UID and SUN responses - preventing unauthorized modification or cloning.
