For engineers reviewing the MF3D4200DA6/01J datasheet, MF3D4200DA6/01J pinout, MF3D4200DA6/01J application, or MF3D4200DA6/01J equivalent, key selection considerations include its 4 KB memory capacity, MOB6 package with SOT500-3 footprint, EV2-specific Transaction MAC and MIsmartApp features, and backward compatibility with MIFARE DESFire EV1 and D40 systems.

Technical Context

The MF3D4200DA6/01J implements a dedicated ISO/IEC 14443-4 RF interface with configurable FSCI supporting up to 128-byte frame size (for 2/4/8 kB variants), operates at 13.56 MHz, and integrates hardware-accelerated AES-128 and 3DES cryptographic engines with key versioning. Its on-chip memory management supports dynamic file creation and automatic anti-tear protection across all file types.

It delivers mutual three-pass authentication per ISO/IEC 7816-4, supports optional Random ID for privacy, and includes Proximity Check and Originality Check sensors to counter relay attacks and verify genuine NXP silicon. The device enables shared file access across two applications within a single transaction and supports up to 14 keys per application with multiple key sets.

FAQ

What security certifications does the MF3D4200DA6/01J hold?

The MF3D4200DA6/01J holds Common Criteria EAL5+ certification for both hardware and software, meeting the same security assurance level required for banking cards and electronic passports. This certification covers its cryptographic engines, memory protection mechanisms, and secure messaging protocols - all verified under independent evaluation. The MF3D4200DA6/01J implements mutual three-pass authentication, hardware AES-128, and on-chip exception sensors to fulfill EAL5+ requirements.

Does the MF3D4200DA6/01J support backward compatibility with older MIFARE systems?

Yes, the MF3D4200DA6/01J operates in default delivery configuration as a MIFARE DESFire EV1 device and maintains functional backward compatibility with both MIFARE DESFire EV1 and MF3ICD40 (D40) systems. It supports D40-native and EV1 secure messaging modes alongside its native EV2 secure messaging. All legacy commands, file structures, and authentication flows remain operational without modification to existing reader firmware or infrastructure.

What is the purpose of the Transaction MAC file type in the MF3D4200DA6/01J?

The Transaction MAC file type in the MF3D4200DA6/01J generates cryptographically signed transaction proofs on-card using a secret key, providing verifiable evidence of completed operations to backend systems. Unlike generic MACs, this file type binds transaction data, timestamps, and application context into a single tamper-evident signature - enabling offline audit trails, dispute resolution, and replay attack prevention without requiring continuous network connectivity during transaction execution.

How does the MIsmartApp feature work on the MF3D4200DA6/01J?

MIsmartApp on the MF3D4200DA6/01J enables delegated application management by allowing third-party service providers to create, configure, and manage their own applications on the same card without PICC-level privileges. This is achieved through dedicated key hierarchies and isolated AID namespaces - ensuring application autonomy while preserving overall card security. The MF3D4200DA6/01J enforces strict access control so that one application cannot interfere with another's keys or data.

What package type and footprint does the MF3D4200DA6/01J use?

The MF3D4200DA6/01J uses the MOB6 plastic leadless module carrier package with SOT500-3 footprint, integrating the IC die, internal matching network, and RF interface into a single surface-mount unit. This package requires no external capacitors or tuning components and is mechanically compatible with standard smart card lamination processes. Its 17 pF input capacitance is optimized for conventional antenna geometries used in ISO/IEC 7816-1/2/3-compliant cards.
