NXP Semiconductors MF3DH4300DA8/00J

Overview

MF3DH4300DA8/00 from NXP Semiconductors is a contactless multi-application smart card IC compliant with ISO/IEC 14443A, featuring Common Criteria EAL5+ hardware and software security certification, 4 kB non-volatile memory, 70 pF input capacitance, and support for AES-128 and 3DES cryptographic engines. It serves as the secure core of transit cards, e-ID documents, and micro-payment systems requiring high-assurance authentication and transaction integrity.

For engineers reviewing the MF3DH4300DA8/00 datasheet, MF3DH4300DA8/00 pinout, MF3DH4300DA8/00 application, or MF3DH4300DA8/00 equivalent, key selection criteria include its 70 pF high-input-capacitance variant optimized for compact antenna designs, EV3-specific features like Transaction MAC and Proximity Check, backward compatibility with DESFire EV2/EV1, and SOT500-4 MOA8 module packaging for embedded smart card inlays.

Technical Context

The MF3DH4300DA8/00 implements a dedicated ISO/IEC 14443A RF interface with configurable frame size (up to 256 bytes), supports native AFh chaining and ISO/IEC 14443-4 protocol, and integrates hardware-accelerated AES-128 and 3DES cryptographic engines with key versioning. Its on-chip security architecture includes mutual three-pass authentication, hardware exception sensors (voltage, temperature, light, glitch), and self-securing file system enforcement.

It delivers transaction-oriented data integrity via automatic anti-tear mechanisms and the new Transaction Timer feature to prevent Man-in-the-Middle attacks during delayed transaction termination. The device enables delegated application management (MIsmartApp) with factory-loaded DAM keys for NXP AppXplorer cloud integration and supports Virtual Card Architecture for privacy-preserving multi-VC card selection.

FAQ

What security certifications does MF3DH4300DA8/00 hold?

MF3DH4300DA8/00 is certified to Common Criteria EAL5+ for both hardware and software, matching the assurance level required for banking cards and electronic passports. This certification covers its cryptographic engines (AES-128, 3DES), mutual authentication protocols, anti-tampering sensors, and secure file system implementation - all validated under CC evaluation scope defined in the official NXP certification report.

How does the 70 pF input capacitance of MF3DH4300DA8/00 affect antenna design?

The 70 pF input capacitance of MF3DH4300DA8/00 reduces the required external tuning capacitance in compact antenna layouts, enabling smaller coil sizes and thinner card profiles. Unlike 17 pF variants, it allows direct integration into space-constrained inlays without additional capacitors - simplifying RF matching and improving yield in high-frequency NFC reader environments.

Is MF3DH4300DA8/00 backward compatible with older MIFARE DESFire systems?

Yes, MF3DH4300DA8/00 operates in default delivery configuration as a MIFARE DESFire EV2 device, ensuring seamless integration with existing EV2 infrastructure. All EV1 and D40 commands remain functional, and migration to EV3-specific features like Transaction MAC or Proximity Check requires explicit activation via standardized commands - preserving legacy reader compatibility.

What file types does MF3DH4300DA8/00 support, and how are they used?

MF3DH4300DA8/00 supports six file types: Standard Data, Backup Data, Value, Linear Record, Cyclic Record, and Transaction MAC. Value files enable secure e-purse functionality with atomic increment/decrement; Transaction MAC files generate per-transaction signatures for backend audit; and cyclic record files store rolling logs for access control or usage analytics - all managed independently per application.

Does MF3DH4300DA8/00 support NFC Forum Type 4 Tag operation?

Yes, MF3DH4300DA8/00 is NFC Forum Type 4 Tag certified (Certificate ID 58652). It supports NDEF message mirroring via Secure Dynamic Messaging (SDM), allowing text-based NFC interactions such as URL launching or Bluetooth pairing while maintaining cryptographic separation from application data stored in DESFire files.
