NXP Semiconductors MF3DH2201DUF/00V

Overview

MF3DH2201DUF/00V from NXP Semiconductors is a contactless multi-application IC compliant with ISO/IEC 14443A, featuring 2 KB EEPROM, 70 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 unified public transport, e-payment, and access control on a single credential.

For engineers reviewing the MF3DH2201DUF/00V datasheet, MF3DH2201DUF/00V pinout, MF3DH2201DUF/00V application, or MF3DH2201DUF/00V equivalent, key selection considerations include its high-input-capacitance (70 pF) wafer form factor for thin card designs, EV2-specific Transaction MAC and MIsmartApp delegation features, and backward compatibility with MIFARE DESFire EV1 and D40 systems.

Technical Context

The MF3DH2201DUF/00V 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 hardware-accelerated AES-128 and triple-DES cryptographic engines with key versioning. Its on-chip TRNG, voltage/rail/light/glitch sensors, and active shielding enforce tamper resistance.

It uses a flexible file system with no limit on application count, up to 32 files per application across six file types-including Transaction MAC-and enforces mutual three-pass authentication with optional Random ID for privacy. The chip supports both native DESFire commands and ISO/IEC 7816-4 APDU wrappers for interoperability with standard NFC readers.

Key Specifications

Pinout & Package

MF3DH2201DUF/00V is supplied in FFC (Film Frame Carrier) wafer format: 8-inch diameter, sawn, 75 μm thickness. No discrete pins or terminals - it is a bare die intended for embedding into contactless smart cards or inlays via flip-chip or wire bonding. Electrical interface is exclusively contactless (ISO/IEC 14443A RF coil coupling).

FAQ

What is the primary security certification level of the MF3DH2201DUF/00V?

The MF3DH2201DUF/00V holds Common Criteria EAL5+ certification for both hardware and software - the highest publicly available assurance level for smart card ICs, matching that required for banking cards and electronic passports. This certification validates its resistance to side-channel, fault injection, and logical attacks, and confirms that all security-critical firmware and hardware logic have undergone rigorous independent evaluation. MF3DH2201DUF/00V achieves this through on-die sensors, active shielding, and hardware-accelerated crypto engines.

Does the MF3DH2201DUF/00V support ISO/IEC 7816-4 commands?

Yes, the MF3DH2201DUF/00V fully supports ISO/IEC 7816-4 APDU structure and file system semantics, 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). It also supports ISO/IEC 7816-4 APDU wrappers for native DESFire commands, enabling seamless integration with existing PKI-based middleware and Java Card platforms without protocol translation layers.

How does the 70 pF input capacitance of the MF3DH2201DUF/00V affect system design?

The 70 pF input capacitance of the MF3DH2201DUF/00V is optimized for small-form-factor antennas with limited loop area - such as those in slim transit cards, wearables, or embedded inlays - where standard 17 pF devices suffer from insufficient coupling. This higher capacitance lowers the resonant impedance mismatch, improving power harvesting efficiency at 13.56 MHz and extending reliable read range in mechanically constrained designs. Antenna tuning must account for this value to avoid detuning or reduced field strength.

Can the MF3DH2201DUF/00V operate in backward-compatible mode with legacy MIFARE DESFire EV1 systems?

Yes, the MF3DH2201DUF/00V ships in default delivery configuration as a drop-in replacement for MIFARE DESFire EV1, supporting all EV1 commands, file structures, and cryptographic modes (2TDEA, 3TDEA, AES). New EV2 features - including Transaction MAC, MIsmartApp, and Proximity Check - require explicit activation via dedicated commands and do not interfere with existing EV1 infrastructure. This allows phased migration without reader or middleware changes.

What file types are supported by the MF3DH2201DUF/00V, and how does the Transaction MAC file enhance security?

The MF3DH2201DUF/00V supports six file types: Standard Data, Backup Data, Value, Linear Record, Cyclic Record, and Transaction MAC. The Transaction MAC file generates an 8-byte CMAC over transaction data using a secret application key stored securely on the IC - producing a cryptographically binding proof that the transaction occurred on a genuine MF3DH2201DUF/00V. This prevents replay, modification, or forgery of transaction logs in backend reconciliation, especially critical for fare collection and micro-payment audit trails.
