Product details
Overview
MF2DL1001DUF/02V 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 NFC-enabled loyalty cards.
For engineers reviewing the MF2DL1001DUF/02V datasheet, MF2DL1001DUF/02V pinout, MF2DL1001DUF/02V application, or MF2DL1001DUF/02V equivalent, key selection considerations include its 17 pF antenna interface for Class 1 smart card designs, transaction-safe value file with upper/lower limits, LRP-wrapped AES for side-channel resistance, and functional compatibility with MIFARE DESFire EV2 for multi-application integration.
Technical Context
The MF2DL1001DUF/02V implements a dedicated contactless PICC architecture compliant with ISO/IEC 14443-2/3/4 and ISO/IEC 7816-4, featuring an integrated analog front-end with 13.56 MHz RF interface, on-die power regulator, and AES-128 co-processor with optional Leakage Resilient Primitive (LRP) wrapping. Its memory controller enforces atomic transaction commit/rollback for value and record files via built-in anti-tearing logic.
It supports configurable communication modes - Plain, CMAC-protected, or Full Enciphered plus CMAC - per file or command, with five customer-defined AES keys, individual file-level access control (Read/Write/ReadWrite/Change), and optional Random ID for GDPR-aligned privacy. The device operates without external power, drawing energy solely from the RF field.
Key Specifications

Pinout & Package
MF2DL1001DUF/02V is supplied in FFC (Film Frame Carrier) wafer format - sawn, 75 μm thickness, Au bumps - intended for embedding into plastic cards, key fobs, or wristbands. It has no conventional package pins; electrical connection is made exclusively via two antenna terminals (LA and LB) bonded to an external coil.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LA | Antenna coil connection A | Primary RF input terminal; connects to one end of the printed or embedded antenna loop - forms resonant LC tank with internal 17 pF capacitance. |
| LB | Antenna coil connection B | Secondary RF input terminal; completes antenna interface path - enables differential coupling and optimal power harvesting from reader field. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless application IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MF2DL1001DUD/02 | Same die, 120 μm wafer thickness, 17 pF input capacitance - identical RF performance but thicker substrate. | Preferred for standard smart cards where mechanical robustness outweighs ultra-thin form factor needs. | Select MF2DL1001DUD/02 when card lamination process requires higher wafer rigidity; MF2DL1001DUF/02 is optimal for thin wristbands or flexible substrates. |
| MF2DLH1001DUF/02 | Same wafer format (75 μm), but 50 pF input capacitance - designed for small-form-factor devices like key fobs with miniaturized antennas. | Required for compact NFC tokens where antenna size limits achievable Q-factor and coupling efficiency. | Choose MF2DLH1001DUF/02 only when antenna geometry mandates >30 pF loading; MF2DL1001DUF/02 maintains optimal range in standard card layouts. |
Compared with MF2DL1001DUD/02 and MF2DLH1001DUF/02, the MF2DL1001DUF/02 uniquely balances 75 μm thinness with 17 pF capacitance - delivering maximum read range in space-constrained yet standard-antenna applications, without requiring antenna redesign or sacrificing mechanical yield.

FAQ
What is the primary function of the MF2DL1001DUF/02V in a contactless system?
The MF2DL1001DUF/02V serves as a secure contactless PICC (Proximity Integrated Circuit Card) that executes ISO/IEC 14443-4 transactions, performs AES-128 mutual authentication, and manages application data in a fixed ISO/IEC 7816-4 file structure. Its role is to validate credentials, store transactional data (e.g., value balances or logs), and ensure cryptographic integrity - all without external power. The MF2DL1001DUF/02V is not a reader IC or MCU; it operates solely as a passive, field-powered endpoint.
Does the MF2DL1001DUF/02V support NFC Forum Type 4 Tag operation?
Yes, the MF2DL1001DUF/02V supports NFC Forum Type 4 Tag functionality through its ISO/IEC 7816-4 file system, configurable AID/FID, and default ATS parameters aligned with NFC Digital Protocol. It responds to ISOSelectFile and ISOReadBinary commands, delivers FCI data from file 1Fh, and enables smartphone-initiated services like business card sharing. This capability is inherent to the MF2DL1001DUF/02V design and does not require firmware modification.
How does the MF2DL1001DUF/02V handle power loss during a value file debit operation?
The MF2DL1001DUF/02V implements hardware-enforced transaction atomicity: debit operations on the value file are held in volatile state until CommitTransaction is successfully executed. If RF power is lost before commit, the original value remains intact and fully recoverable. This anti-tearing mechanism is built into the MF2DL1001DUF/02V's memory controller and requires no host-side error recovery logic - ensuring balance consistency even in high-interference environments like subway gates.
What antenna design guidance applies to the MF2DL1001DUF/02V?
The MF2DL1001DUF/02V specifies 17 pF input capacitance and is optimized for standard ISO/IEC 14443 Class 1 smart card antenna layouts (e.g., ~7–8 cm² copper area, 1–2 μH inductance). Its LA/LB terminals connect directly to the coil ends; no external capacitor is needed. Antenna tuning must target resonance at 13.56 MHz with this 17 pF load. Deviating from this value - such as using a 50 pF variant - will reduce read range and reliability in standard card formats.
Can the MF2DL1001DUF/02V be used alongside MIFARE DESFire EV2 in the same system?
Yes, the MF2DL1001DUF/02V offers functional compatibility with MIFARE DESFire EV2: it supports a subset of EV2 commands (e.g., Authenticate, ReadData, WriteData), shares the same file system structure and secure messaging framework, and allows applications developed for MF2DL1001DUF/02V to operate within an EV2 multi-application environment. This compatibility is explicitly documented in the MF2DL(H)x0 datasheet and requires no hardware change - only application-layer adaptation for extended EV2 features.
