Overview

MF3D8201DUD/01V from NXP Semiconductors is a contactless multi-application smart card 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 transit cards, e-ID documents, and micro-payment systems requiring high-integrity transaction handling.

For engineers reviewing the MF3D8201DUD/01V datasheet, MF3D8201DUD/01V pinout, MF3D8201DUD/01V application, or MF3D8201DUD/01V equivalent, key selection considerations include its 8 KB NV memory capacity, EAL5+ hardware/software security rating, Transaction MAC file support, MIsmartApp delegated management capability, and backward compatibility with MIFARE DESFire EV1 and D40 infrastructure.

Technical Context

The MF3D8201DUD/01V implements a dedicated ISO/IEC 14443-4 RF interface with configurable FSCI supporting up to 128-byte frame size (256 bytes for larger memory variants), operates at 13.56 MHz, and integrates on-chip TRNG, voltage/rail/light/glitch sensors, and active shielding for side-channel attack resistance. Its CPU executes a certified secure operating system enabling application-level authentication and encrypted data transfer.

It supports three secure messaging protocols-D40-native, EV1-compatible, and EV2-native-with AES-128-based EV2 Secure Messaging as the recommended mode for new designs. File-level access control uses up to 14 keys per application, with multiple key sets and rolling mechanisms enabled for dynamic credential lifecycle management.

Key Specifications

Pinout & Package

MF3D8201DUD/01V is supplied in FFC (Film Frame Carrier) packaging - an 8-inch sawn wafer format with 120 μm thickness, intended for embedding into laminated smart cards or modules. No discrete pins or terminals are present; electrical interface is exclusively via integrated coil coupling under ISO/IEC 14443A.

FAQ

What security certifications does the MF3D8201DUD/01V hold?

The MF3D8201DUD/01V holds Common Criteria EAL5+ certification for both hardware and software components - the same assurance level required for banking cards and electronic passports. This certification validates its resistance to physical, fault injection, and side-channel attacks, and confirms secure boot, key management, and cryptographic execution integrity. The MF3D8201DUD/01V achieves this through on-die sensors, active shielding, and a certified secure operating system.

Does the MF3D8201DUD/01V support backward compatibility with older MIFARE DESFire systems?

Yes, the MF3D8201DUD/01V operates in default delivery configuration as a MIFARE DESFire EV1 device, supporting all EV1 commands and D40-native secure messaging. It maintains full interoperability with existing MIFARE DESFire EV1 and MF3ICD40 reader infrastructure. New EV2 features - such as Transaction MAC, MIsmartApp, and Proximity Check - require explicit activation via configuration commands and do not affect legacy operation.

What is the difference between MF3D8201DUD/01V and MF3DH8201DUD/01?

The MF3D8201DUD/01V uses 17 pF input capacitance and is optimized for standard antenna layouts in conventional smart cards, whereas MF3DH8201DUD/01 uses 70 pF input capacitance for enhanced coupling in miniaturized or flexible form factors. Both share identical 8 KB EEPROM, cryptographic capabilities, and command set. The "H" suffix denotes high-capacitance tuning - critical when antenna size is constrained, but unnecessary for standard ISO/IEC 7816-1 ID-1 card designs.

Can the MF3D8201DUD/01V store more than one application, and how is isolation enforced?

Yes, the MF3D8201DUD/01V supports unlimited applications, each with up to 32 files and independent key sets (up to 14 keys per application). Isolation is enforced at the hardware level: applications are logically separated by Application Identifiers (AIDs), and file access requires explicit authentication using application-specific keys. The MMU prevents cross-application memory access, and the secure OS enforces strict privilege boundaries - even the PICC master key cannot read application file contents without knowledge of the application's own keys.

What file types does the MF3D8201DUD/01V support, and what is the purpose of the Transaction MAC file?

The MF3D8201DUD/01V supports six file types: Standard Data, Backup Data, Value, Linear Record, Cyclic Record, and Transaction MAC. The Transaction MAC file generates a cryptographically signed digest of transaction data - including timestamps, amounts, and counters - using a secret key stored on the chip. This provides non-repudiable proof of transaction occurrence and integrity, enabling backend reconciliation without requiring online connectivity during the tap event. The MF3D8201DUD/01V computes and stores this MAC autonomously during each transaction.
