NXP Semiconductors MF3D8201DUF/00V

Overview

MF3D8201DUF/00V from NXP Semiconductors is a contactless multi-application IC compliant with ISO/IEC 14443A, featuring 8 KB EEPROM, 17 pF input capacitance, Common Criteria EAL5+ security certification, and support for AES-128 and 3DES cryptographic engines. It serves as the secure core of smart city mobility cards, enabling public transport, e-payment, and access control on a single credential.

For engineers reviewing the MF3D8201DUF/00V datasheet, MF3D8201DUF/00V pinout, MF3D8201DUF/00V application, or MF3D8201DUF/00V equivalent, key selection considerations include its 8 KB NV memory capacity, 17 pF low-input-capacitance wafer form factor (75 μm thickness), EV2-specific Transaction MAC and MIsmartApp features, and backward compatibility with MIFARE DESFire EV1 and D40 systems.

Technical Context

The MF3D8201DUF/00V 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 unit (MMU) enforces strict application isolation using per-application key sets and file-level access rights.

Security architecture includes mutual three-pass authentication, hardware exception sensors (glitch, voltage, temperature, light), Proximity Check against relay attacks, Originality Check for NXP authenticity, and transaction-oriented anti-tear backup across all file types. It supports both fixed UID and optional Random ID modes per ISO/IEC 14443-3.

Key Specifications

Pinout & Package

MF3D8201DUF/00V is supplied in FFC (Film Frame Carrier) wafer format - a bare die configuration without physical pins or terminals. It is designed for direct embedding into smart card laminates or inlays, where RF coupling occurs via integrated antenna traces. No discrete pinout applies; electrical interface is exclusively contactless via the 13.56 MHz magnetic field.

FAQ

What security certifications apply to the MF3D8201DUF/00V?

The MF3D8201DUF/00V holds Common Criteria EAL5+ certification for both hardware and software components - the same assurance level used in banking cards and e-passports. This covers its cryptographic engines (AES-128, 3DES), memory protection mechanisms, and secure messaging protocols. The certification explicitly validates the implementation of mutual three-pass authentication, Transaction MAC generation, and Proximity Check functionality as defined in the MF3D8201DUF/00V product specification.

Does the MF3D8201DUF/00V support ISO/IEC 7816-4 commands?

Yes, the MF3D8201DUF/00V fully supports ISO/IEC 7816-4 APDU structure and file system commands including SELECT FILE (INS A4), READ BINARY (B0), UPDATE BINARY (D6), READ RECORDS (B2), APPEND RECORD (E2), GET CHALLENGE (84), INTERNAL AUTHENTICATE (88), and EXTERNAL AUTHENTICATE (82). These operate natively over the ISO/IEC 14443-4 contactless interface, enabling interoperability with existing smart card middleware and PKI infrastructure without protocol translation layers.

How does the Transaction MAC feature work in the MF3D8201DUF/00V?

The MF3D8201DUF/00V implements Transaction MAC at the application level using a secret key stored in secure memory. During each transaction, it computes a cryptographically signed MAC over the transacted data (e.g., balance change, timestamp, counter) and returns it to the reader. This MAC serves as irrefutable proof that the transaction occurred on a genuine MF3D8201DUF/00V device and was not replayed or altered - enabling backend systems to validate transaction integrity without requiring online verification for every tap.

Is the MF3D8201DUF/00V backward compatible with older MIFARE DESFire systems?

Yes, the MF3D8201DUF/00V operates in default delivery mode as a MIFARE DESFire EV1 device, supporting all EV1 and D40 native commands, cryptographic methods (2TDEA, 3TDEA), and secure messaging protocols. New EV2 features like Transaction MAC and MIsmartApp require explicit activation via dedicated commands. Infrastructure upgrades are optional - existing readers and host systems continue full operation without modification.

What is the difference between MF3D8201DUF/00V and MF3D8201DUF/01?

The MF3D8201DUF/00V and MF3D8201DUF/01 share identical electrical specifications (8 KB EEPROM, 17 pF input capacitance, 75 μm thickness) and functional capabilities. The suffix "/00V" denotes a specific wafer lot or qualification batch under NXP's internal revision control, while "/01" indicates a later production revision. Both are functionally interchangeable in design; no datasheet parameter or command behavior differs between them - only traceability and manufacturing date vary.
