Product details
Overview
MF2DL1001DUD/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 interoperability with NFC-enabled mobile handsets and legacy proximity readers in transport ticketing and access management.
For engineers reviewing the MF2DL1001DUD/02Z datasheet, MF2DL1001DUD/02Z pinout, MF2DL1001DUD/02Z application, or MF2DL1001DUD/02Z equivalent, key selection considerations include its fixed 6-file memory structure, LRP-wrapped AES side-channel resistance, Transaction Message Authentication (TMAC) support, 10 cm reading distance capability, and compatibility with MIFARE DESFire EV2 multi-application ecosystems.
Technical Context
The MF2DL1001DUD/02Z implements a dedicated contactless PICC (Proximity Integrated Circuit Card) architecture compliant with ISO/IEC 14443-2/3/4 Type A, supporting data rates up to 848 kbit/s and configurable ATS parameters including frame size (up to 128 bytes) and communication speed negotiation via PPS. Its analog front-end integrates a rectifier, band-gap reference, voltage/current sensors, and resonance capacitor interface optimized for 13.56 MHz operation.
Digital execution relies on an embedded CPU/MMU with ROM firmware, AES-128 co-processors, CRC and TRNG engines, and a memory management unit governing EEPROM (640 bytes), RAM, and security registers. File-level access control is enforced per EF using five customer-defined AES keys, with flexible communication modes (Plain, MAC-protected, Full Enciphered+CMAC) applied at both command and file level.

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 |
|---|---|---|---|
| MF2DLH1001DUD/02 | Same core functionality but with 50 pF input capacitance - optimized for small-form-factor designs (e.g., wristbands, key fobs) rather than standard smart cards. | Required for compact antenna geometries where 17 pF would limit coupling efficiency and read range below 5 cm. | Select MF2DLH1001DUD/02 when designing for non-standard form factors with constrained antenna area; otherwise MF2DL1001DUD/02 provides superior range in card-sized implementations. |
| MF2DL1000DA8/02 | Identical 17 pF capacitance and memory structure, but packaged in MOA8 plastic leadless module carrier (SOT500-4) - ready-to-mount surface-mount device instead of wafer form. | Eliminates need for custom antenna integration; targets module-level OEMs requiring drop-in IC replacement without wafer handling or bump bonding. | Choose MF2DL1000DA8/02 for rapid prototyping or low-volume production where wafer-level assembly is impractical; MF2DL1001DUD/02 suits high-volume smart card manufacturers with established bump/wafer processing. |
Compared with MF2DLH1001DUD/02 and MF2DL1000DA8/02, the MF2DL1001DUD/02 offers optimal RF performance in standard smart card layouts due to its 17 pF input capacitance, while retaining full functional equivalence - making it the preferred choice for cost-sensitive, high-volume card personalization workflows requiring maximum read range and legacy infrastructure compatibility.

FAQ
What is the primary function of the MF2DL1001DUD/02Z in a contactless system?
The MF2DL1001DUD/02Z functions as a secure contactless PICC (Proximity Integrated Circuit Card) IC that executes ISO/IEC 14443-4-compliant transactions, stores application data in a fixed six-file ISO/IEC 7816-4 structure, and performs AES-128 authentication. It serves as the trusted element in smart cards for transport, access, and loyalty - handling value operations, cyclic logging, and cryptographic message integrity without requiring an external microcontroller.
Does the MF2DL1001DUD/02Z support NFC Forum Type 4 Tag operation?
Yes, the MF2DL1001DUD/02Z supports NFC Forum Type 4 Tag operation through its ISO/IEC 7816-4 file system, configurable AID/FID, and compatibility with ISO/IEC 14443-4 wrapped commands. When configured with appropriate ATS and file naming, it enables smartphone-initiated services like business card sharing or peer-to-peer pairing - extending its utility beyond traditional reader-based applications.
How does the Transaction Message Authentication (TMAC) feature work in the MF2DL1001DUD/02Z?
The MF2DL1001DUD/02Z implements TMAC via an optional TransactionMAC File that stores a Transaction MAC Counter (TMC) and Transaction MAC Value (TMV). On successful CommitTransaction, the IC automatically updates both fields using a dedicated TMAC key. This allows clearing entities to cryptographically verify transaction completeness and integrity - even if the original PCD response was lost - by reading the committed TMV and comparing it against locally computed values.
What memory configuration is implemented in the MF2DL1001DUD/02Z?
The MF2DL1001DUD/02Z contains 640 bytes of user EEPROM organized into six fixed ISO/IEC 7816-4 Elementary Files: three Standard Data Files (32, 256, and 256 bytes), one Value File (4-byte signed integer with upper/lower limits), one Cyclic Record File (4 × 16-byte entries), and one optional TransactionMAC File. All files except TMAC are statically created and cannot be deleted, though their IDs and access rights are configurable.
Is the MF2DL1001DUD/02Z pin-compatible with other MIFARE DESFire variants?
No - the MF2DL1001DUD/02Z is supplied in FFC wafer format with only LA/LB antenna terminals and no conventional I/O pins. It is not pin-compatible with packaged variants like MF2DL1000DA8/02 (MOA8) or MF2DL1000DA4/02 (MOA4), which use SOT500-4 or SOT500-2 footprints. However, it shares identical logical command sets, memory layout, and security architecture with those variants - enabling software-level interoperability across form factors.
