NXP Semiconductors MF3D8300DA8/00J

Overview

MF3D8300DA8/00 from NXP Semiconductors is a MIFARE DESFire EV3 contactless multi-application IC with 8 kB non-volatile memory, 17 pF input capacitance, Common Criteria EAL5+ hardware and software certification, ISO/IEC 14443A compliance, and support for AES-128 and 3DES cryptographic engines. It enables secure public transport ticketing, micro-payment, and multi-service smart city cards.

For engineers reviewing the MF3D8300DA8/00 datasheet, MF3D8300DA8/00 pinout, MF3D8300DA8/00 application, or MF3D8300DA8/00 equivalent, key selection considerations include memory size (8 kB), input capacitance (17 pF), backward compatibility with DESFire EV2/EV1/D40, Transaction MAC file support, and Virtual Card Architecture for privacy-preserving card selection.

Technical Context

The MF3D8300DA8/00 implements a dedicated 32-bit CPU with ROM-based firmware, hardware AES-128 and triple-DES cryptographic accelerators, and on-chip TRNG. Its memory management unit (MMU) enforces strict isolation between applications, each supporting up to 32 files across six types-including Transaction MAC and cyclic record files-with per-application key sets and access rights.

It operates at 13.56 MHz with ISO/IEC 14443-4 protocol support, configurable frame size (up to 256 bytes), and optional Random ID generation. Security features include mutual three-pass authentication, Proximity Check against relay attacks, Originality Check for genuine NXP validation, and automatic anti-tear with Transaction Timer to prevent man-in-the-middle transaction delay.

Key Specifications

Pinout & Package

MF3D8300DA8/00 is supplied in MOA8 plastic leadless module carrier package (SOT500-4), designed for embedding into contactless smart cards, wearables, and secure tokens. It interfaces exclusively via RF coil coupling-no physical pins or solderable terminals are present. The device has no electrical I/O pads; all communication and power are delivered wirelessly through the integrated antenna interface per ISO/IEC 14443A.

FAQ

What is the memory capacity and organization of the MF3D8300DA8/00?

The MF3D8300DA8/00 integrates 8 kB of non-volatile memory organized as a flexible, application-isolated file system. Each application supports up to 32 files across six types-including Standard Data, Value, Cyclic Record, and Transaction MAC files-with file sizes defined at creation. This structure enables concurrent deployment of transport, payment, and access applications on a single MF3D8300DA8/00 IC without interference.

Does the MF3D8300DA8/00 support backward compatibility with older MIFARE DESFire generations?

Yes, the MF3D8300DA8/00 is functionally backward compatible with MIFARE DESFire EV2, EV1, and D40 (MF3ICD40) in its default configuration. It supports legacy secure messaging modes (D40 Native, EV1, EV2) alongside native EV3 commands, allowing infrastructure upgrades without replacing existing readers or reissuing cards - all while maintaining full EAL5+ security for new deployments.

What security certifications apply to the MF3D8300DA8/00?

The MF3D8300DA8/00 holds Common Criteria EAL5+ certification for both hardware and software, matching the assurance level required for electronic passports and banking cards. It also achieves NFC Forum Type 4 Tag certification (ID 58652) and supports ISO/IEC 7816-4 APDU commands - ensuring interoperability with global smart card infrastructure and regulatory compliance for high-trust applications.

How does the Transaction Timer feature enhance security in the MF3D8300DA8/00?

The Transaction Timer in the MF3D8300DA8/00 prevents man-in-the-middle attacks by enforcing strict time limits on transaction execution. If a malicious reader delays finalizing a transaction after the card leaves its field, the MF3D8300DA8/00 automatically aborts the session - ensuring no partial or manipulated data commits to memory and preserving end-to-end integrity for fare deductions, access grants, or payment authorizations.

Is the MF3D8300DA8/00 suitable for wearable or compact form factor designs?

The MF3D8300DA8/00 uses the MOA8 package (SOT500-4) optimized for module-level integration, not ultra-thin wearables. For wristbands or key fobs, MF3DH8300DA8/00 (70 pF version) is recommended due to its higher input capacitance enabling efficient coupling with miniaturized antennas. The MF3D8300DA8/00 remains ideal for standard ISO/IEC 7816-1/2-compliant smart cards and secure tokens where mechanical durability and reader interoperability are prioritized.
