Product details
Overview
MF2DLH1000DA4/02J from NXP Semiconductors is a contactless application IC implementing the MIFARE DESFire Light platform for secure authentication in single-entity managed systems. It features 640 bytes of user memory, AES-128 security with five customer-defined keys, 50 pF input capacitance for small-form-factor antenna designs, and full ISO/IEC 14443-4 and ISO/IEC 7816-4 compliance - enabling use in transport ticketing, access management, and NFC-enabled loyalty cards.
For engineers reviewing the MF2DLH1000DA4/02J datasheet, MF2DLH1000DA4/02J pinout, MF2DLH1000DA4/02J application, or MF2DLH1000DA4/02J equivalent, key selection considerations include its 50 pF input capacitance (optimized for wristbands/key fobs), LRP-wrapped AES side-channel resistance, TMAC support for transaction integrity, and functional compatibility with MIFARE DESFire EV2 for multi-application integration.
Technical Context
The MF2DLH1000DA4/02J implements a file-based ISO/IEC 7816-4 memory structure with six pre-defined elementary files: three standard data files (32 B + 2 × 256 B), one 4-record cyclic log file (16 B/record), one value file with signed integer and bounds, and an optional TMAC file. Its RF interface supports ISO/IEC 14443A-2/3/4 at 13.56 MHz with data rates up to 848 kbit/s and double-size (7-byte) UID or configurable Random ID.
Security architecture includes 3-pass mutual authentication, per-file access control using five AES-128 keys, optional LRP-wrapped AES for enhanced fault and side-channel resilience, and configurable communication modes (Plain / CMAC-protected / Full Enciphered+CMAC). Transaction management ensures atomicity via anti-tearing mechanisms and CommitTransaction enforcement.

FAQ
What is the primary function of the MF2DLH1000DA4/02J in a contactless system?
The MF2DLH1000DA4/02J serves as a secure contactless application IC implementing the MIFARE DESFire Light platform. It performs mutual authentication, stores application data in a standardized ISO/IEC 7816-4 file structure, executes atomic value and record operations, and supports cryptographic message integrity via optional TMAC. Its 50 pF input capacitance makes it especially suitable for compact form factors like wristbands and key fobs where antenna size is constrained.
How does the 50 pF input capacitance of the MF2DLH1000DA4/02J impact antenna design?
The 50 pF input capacitance of the MF2DLH1000DA4/02J is specifically engineered to resonate efficiently with smaller loop antennas used in key fobs, wristbands, and thin cards. Unlike the 17 pF variant (e.g., MF2DL1000DA4/02), this higher capacitance lowers the required antenna inductance, enabling shorter trace lengths and reduced coil area while maintaining reliable 10 cm read range and low-power operation under ISO/IEC 14443A constraints.
Does the MF2DLH1000DA4/02J support NFC Forum Type 4 Tag functionality?
Yes, the MF2DLH1000DA4/02J supports NFC Forum Type 4 Tag operation through its ISO/IEC 7816-4 compliant file system, configurable AID/FID, and support for ISO/IEC 14443-4 wrapped commands. Users can assign NFC-compliant application identifiers and file IDs to enable business card sharing, peer-to-peer pairing, and other end-user services - all while retaining full MIFARE DESFire Light security features including AES-128 and LRP-wrapped cryptography.
What security certifications apply to the MF2DLH1000DA4/02J?
The MF2DLH1000DA4/02J holds Common Criteria EAL4 certification for both hardware and software, validating its resistance to physical, logical, and side-channel attacks. Its AES-128 implementation complies with NIST SP 800-38A/B, and optional LRP wrapping provides enhanced protection against differential power analysis (DPA) and fault injection. The IC also supports ECC-based NXP originality signatures and configurable access rights per file to enforce granular data protection policies.
Can the MF2DLH1000DA4/02J be used interchangeably with MIFARE DESFire EV2 platforms?
The MF2DLH1000DA4/02J is functionally compatible with MIFARE DESFire EV2 for single-application deployment and supports a subset of EV2 commands, file structures, and secure messaging protocols. However, it is not a drop-in replacement: it lacks EV2's multi-application support, extended key management, and advanced cryptographic options. Applications developed on MF2DLH1000DA4/02J can be integrated into broader EV2 ecosystems, but require validation of command coverage and TMAC interoperability before deployment.
