Product details
Overview
MF2DL1000DA4/02J 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 for Class 1 antenna compatibility, and full ISO/IEC 14443-4 compliance - enabling use in transport ticketing, access management, and electronic voucher applications.
For engineers reviewing the MF2DL1000DA4/02J datasheet, MF2DL1000DA4/02J pinout, MF2DL1000DA4/02J application, or MF2DL1000DA4/02J equivalent, key selection considerations include its SOT500-2 MOA4 package with LA/LB antenna terminals, 13.56 MHz RF interface supporting up to 848 kbit/s, EAL4-certified security architecture, and functional compatibility with MIFARE DESFire EV2 for multi-application integration.
Technical Context
The MF2DL1000DA4/02J implements a dedicated contactless smart card controller with ISO/IEC 14443-2/3/4 Type A protocol stack, integrated analog front-end (rectifier, limiter, demodulator, modulator), and digital subsystem including 32-bit CPU, AES-128 co-processor, CRC engine, TRNG, and EEPROM memory controller. Its transaction management enforces atomicity via automatic anti-tearing and optional TMAC-backed commit verification.
Security is enforced at multiple layers: 5 customer-defined AES-128 keys with versioning, per-file configurable access rights (Read/Write/ReadWrite/Change), LRP-wrapped AES for side-channel resistance, optional Random ID (RID), and ECC-based NXP originality signature. Communication modes support Plain, CMAC-protected, or fully enciphered+CMAC operation - all configurable per command or per file.
Key Specifications

Pinout & Package
MF2DL1000DA4/02J is housed in a plastic leadless module carrier package (MOA4) conforming to SOT500-2 outline, designed for embedding into smart cards, tags, or wearable form factors. The device has no active power supply pins - it derives operating energy entirely from the 13.56 MHz RF field.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LA | Antenna coil connection A | Primary terminal for connecting one end of the external LC resonant antenna circuit (typically 1–2 μH inductor + tuning capacitor). |
| LB | Antenna coil connection B | Secondary terminal completing the antenna loop; forms resonant tank with LA and external components for efficient 13.56 MHz energy harvesting. |
Key Features
| Feature | Design Value |
|---|---|
| File-based ISO/IEC 7816-4 structure | Predefined six-file layout (DF + EFs) eliminates custom filesystem development and ensures consistent data modeling across deployments. |
| Transaction-oriented anti-tearing | Hardware-enforced atomic commit/rollback guarantees data consistency during power loss or RF interruption - critical for monetary or audit-log operations. |
| LRP-wrapped AES cryptography | Leakage Resilient Primitive enhances resistance against side-channel and fault injection attacks without requiring external countermeasures. |
| Configurable ATS and UID behavior | Allows customization of Answer-to-Select parameters (e.g., frame size, supported speeds) and enables Random ID for GDPR-compliant privacy protection. |
| MIFARE DESFire EV2 compatibility | Shared command set and file system enables seamless migration of single-application logic into multi-application ecosystems managed by different entities. |
Applications

Use Value: Supports fast, offline redemption with cryptographic verification - preventing duplication or unauthorized modification without reader-side infrastructure. |
Use Scenario: Customer loyalty program where points are earned, redeemed, and audited across multiple store locations. IC Role / Device Role / Timing Role: Maintains encrypted point balance in Value file and activity history in CyclicRecord file for dispute resolution. Use Value: Ensures accurate, tamper-proof point accounting with built-in upper/lower limits and transaction rollback - reducing reconciliation overhead. |
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 |
|---|---|---|---|
| MF2DLH1000DA4/02 | Same MOA4/SOT500-2 package but with 50 pF input capacitance - optimized for small-form-factor devices (e.g., wristbands, key fobs) rather than standard cards. | Requires antenna redesign for lower capacitance; not drop-in compatible with 17 pF layouts. | Select MF2DLH1000DA4/02 only when deploying in compact wearables where reduced antenna size is mandatory. |
| MF2DL1000DA8/02 | Identical 17 pF specification but in MOA8/SOT500-4 package - larger footprint with same electrical interface and pinout (LA/LB). | Offers higher mechanical robustness and thermal margin; suited for industrial or high-reliability card modules. | Choose MF2DL1000DA8/02 when board space permits and enhanced environmental resilience is required over MOA4. |
Compared with MF2DL1000DA4/02J, MF2DLH1000DA4/02 enables miniaturized antenna design at the cost of layout requalification, while MF2DL1000DA8/02 provides identical functionality in a mechanically more robust package - making both viable alternatives depending on form factor and reliability priorities.
