Product details
Overview
MF2DL1001DUF/02Z from NXP Semiconductors is a contactless application IC implementing the MIFARE DESFire Light platform for secure, single-entity smart card systems. It delivers AES-128 authentication, 640 bytes of ISO/IEC 7816-4 file-based user memory (including three standard data files, one value file, and one cyclic record file), 17 pF input capacitance, and full ISO/IEC 14443-4 compliance - enabling use in transport ticketing, access management, and electronic voucher applications.
For engineers reviewing the MF2DL1001DUF/02Z datasheet, MF2DL1001DUF/02Z pinout, MF2DL1001DUF/02Z application, or MF2DL1001DUF/02Z equivalent, key selection considerations include its 17 pF antenna interface for Class 1 smart card designs, transaction-protected value file with upper/lower limits, LRP-wrapped AES side-channel resistance, TMAC support for payment clearing verification, and functional compatibility with MIFARE DESFire EV2 multi-application environments.
Technical Context
The MF2DL1001DUF/02Z implements a dedicated contactless PICC architecture compliant with ISO/IEC 14443-2/3/4 Type A, supporting data rates up to 848 kbit/s and configurable ATS for legacy terminal interoperability. Its on-die analog front-end includes a rectifier, band-gap reference, and resonance capacitor interface optimized for 13.56 MHz operation with 17 pF input capacitance.
Digital execution relies on an embedded CPU/MMU with ROM firmware, AES-128 co-processors, TRNG, and dedicated security sensors. Memory management enforces atomic transactions via automatic anti-tearing, while file-level access control uses five customer-defined keys and per-file CommMode.Plain/MAC/Full settings aligned with ISO/IEC 7816-4 command semantics.

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless secure application IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MF2DL1001DUD/02 | Same die, identical functionality, but 120 μm wafer thickness and 17 pF input capacitance - optimized for thicker module carriers. | Preferred for MOA8/SOT500-4 modules requiring mechanical robustness; less suitable for ultra-thin wristband or fob form factors. | Select MF2DL1001DUD/02 when module stack height > 0.6 mm is acceptable and higher mechanical yield is prioritized over minimal thickness. |
| MF2DLH1001DUF/02 | Same 75 μm wafer thickness as MF2DL1001DUF/02Z, but 50 pF input capacitance - designed for small-form-factor devices like key fobs and wearables. | Required for compact antenna designs with reduced coil area; incompatible with standard Class 1 smart card antennas calibrated for 17 pF. | Choose MF2DLH1001DUF/02 only when integrating into sub-30 mm diameter fobs or wristbands where antenna size constraints demand higher input capacitance. |
Compared with MF2DL1001DUF/02Z, MF2DL1001DUD/02 offers greater mechanical stability in thicker modules, while MF2DLH1001DUF/02 enables miniaturization at the cost of antenna redesign - neither is pin-compatible nor drop-in replaceable due to differing wafer thickness and capacitance specifications.

FAQ
What is the primary function of the MF2DL1001DUF/02Z in a contactless system?
The MF2DL1001DUF/02Z serves as a secure contactless PICC (Proximity Integrated Circuit Card) implementing the MIFARE DESFire Light platform. It executes ISO/IEC 14443-4 communication, performs AES-128 mutual authentication, manages six pre-defined ISO/IEC 7816-4 files, and enforces transaction-atomic operations - all within a single-die IC. Its role is to securely store and process application data (e.g., transit balances, access credentials) without requiring host-side cryptographic processing. The MF2DL1001DUF/02Z is not a reader IC or MCU; it operates exclusively as a passive, field-powered smart card IC.
Does the MF2DL1001DUF/02Z support NFC Forum Type 4 Tag operation?
Yes, the MF2DL1001DUF/02Z supports NFC Forum Type 4 Tag operation through its ISO/IEC 7816-4 file system and command set. Its default DF name and file structure comply with NFC Type 4 Tag requirements, and users can configure AID and FID to match existing Type 4 deployments. The IC supports NDEF message wrapping via standard ISOReadBinary/ISOUpdateBinary commands on designated StandardData files. However, native NDEF parsing is not implemented - host readers must handle NDEF formatting, while the MF2DL1001DUF/02Z provides secure, authenticated storage and access control for the underlying data.
How does the Transaction Message Authentication Code (TMAC) feature work in the MF2DL1001DUF/02Z?
The TMAC feature in the MF2DL1001DUF/02Z generates a cryptographic checksum over the complete transaction payload - including value changes, record writes, and reader ID - using a dedicated AES-128 TMAC key. This checksum is stored in the TMAC file alongside a transaction counter and is automatically updated only upon successful CommitTransaction. Clearing entities verify the TMAC using the same key, ensuring transaction integrity and preventing tampering or replay. The MF2DL1001DUF/02Z does not compute TMAC on-the-fly during read; it stores committed values for post-transaction validation, making it suitable for offline micropayment reconciliation.
Can the MF2DL1001DUF/02Z be used in wearable form factors like wristbands?
The MF2DL1001DUF/02Z is rated for 17 pF input capacitance and targets standard Class 1 smart card antenna designs, not ultra-small form factors. For wristbands or key fobs with limited antenna area, NXP specifies the MF2DLH1001DUF/02 variant - which uses the same 75 μm wafer but delivers 50 pF input capacitance to compensate for reduced coil inductance. Using MF2DL1001DUF/02Z in a wristband would require antenna redesign to meet 17 pF impedance matching, likely resulting in reduced read range or reliability. Therefore, MF2DL1001DUF/02Z is not recommended for wearables; select MF2DLH1001DUF/02 instead.
What security certifications apply to the MF2DL1001DUF/02Z?
The MF2DL1001DUF/02Z holds Common Criteria EAL4 certification for both hardware and software components, validating its resistance to logical and physical attacks including side-channel analysis and fault injection. It implements AES-128 per NIST SP 800-38A/B, supports 3-pass mutual authentication, and includes ECC-based NXP originality signatures to prevent counterfeiting. The optional LRP wrapper around AES further strengthens side-channel resilience. These certifications are inherited from the MIFARE DESFire Light platform and apply specifically to the MF2DL1001DUF/02Z configuration - no additional evaluation is required for this exact part number.
