Product details
Overview
MF1S7031XDUF/V1 from NXP Semiconductors is a contactless smart card IC compliant with ISO/IEC 14443 Type A, featuring 4 kB EEPROM organized in 40 sectors (32×4-block + 8×16-block), 13.56 MHz operating frequency, 106 kbit/s data rate, and 4-byte non-unique ID (NUID) for cost-sensitive ticketing applications.
For engineers reviewing the MF1S7031XDUF/V1 datasheet, MF1S7031XDUF/V1 pinout, MF1S7031XDUF/V1 application, or MF1S7031XDUF/V1 equivalent, key selection considerations include NUID vs UID security model, FFC bump die packaging for module integration, EEPROM access control granularity, CRYPTO1 authentication timing, and compatibility with MIFARE Classic EV1 reader firmware stacks.
Technical Context
The MF1S7031XDUF/V1 implements a dedicated RF interface per ISO/IEC 14443A with integrated rectifier, voltage regulator, clock regenerator, and Power-On Reset - requiring no external components beyond an antenna coil. Its digital control unit executes anticollision, three-pass mutual authentication, and memory operations using the proprietary CRYPTO1 stream cipher.
Memory is partitioned into 40 sectors with configurable access conditions per sector trailer; each sector trailer holds two 48-bit keys (A mandatory, B optional) and access bits governing read/write/increment/decrement permissions per block type. Value blocks support electronic purse functions with built-in backup management and triple-value storage for integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.56 MHz - Enables interoperability with global ISO/IEC 14443A readers and antennas. |
| Memory Capacity | 4 kB EEPROM - Organized as 40 sectors (32×4 blocks + 8×16 blocks); supports multi-application key hierarchy. |
| Data Rate | 106 kbit/s - Defines maximum transaction throughput; impacts total ticketing time including authentication and I/O. |
| ID Type | 4-byte Non-Unique ID (NUID) - Reduces manufacturing cost vs 7-byte UID; requires application-layer collision handling. |
| Authentication | Mutual three-pass CRYPTO1 - Ensures secure sector-level access; keys and access conditions stored in sector trailers. |
| Write Endurance | 200,000 cycles - Specifies guaranteed reprogrammability of EEPROM blocks under standard ambient conditions. |
| Data Retention | 10 years - Minimum EEPROM data hold time at 22 °C; critical for long-life transit cards and access credentials. |
Pinout & Package
MF1S7031XDUF/V1 is supplied as a bumped die on 8-inch wafer (75 μm thickness), mounted on film frame carrier (FFC Bump). It has no conventional pins; electrical connection is made via two gold bumps - LA and LB - for direct bonding to antenna coil terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LA | Antenna coil connection LA | RF input terminal for one side of planar antenna loop; forms resonant LC tank with external coil and internal capacitance (~16.9 pF). |
| LB | Antenna coil connection LB | RF input terminal for opposite side of antenna loop; completes passive power harvesting and bidirectional data coupling path. |
Key Features
| Feature | Design Value |
|---|---|
| Contactless power & data | No external power supply or components needed - energy harvested from 13.56 MHz reader field powers full operation. |
| Anticollision support | Enables simultaneous presence of multiple cards in reader field; uses cascaded bit-by-bit selection for 4-byte NUID variants. |
| Value block functionality | Hardware-accelerated increment/decrement/transfer/restore with triple-value storage and address backup - essential for e-purse use cases. |
| Configurable access control | Per-sector trailer defines independent read/write/auth permissions for keys A/B across data, value, and trailer blocks. |
| Transaction speed | <100 ms typical end-to-end ticketing transaction - includes anticollision, select, authentication, and memory I/O with backup management. |
Applications
| Public Transportation Ticketing | Access Management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless smart card IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MF1S7001XDUF/V1 | Same FFC bump package and 8-inch wafer form factor, but uses 7-byte unique UID instead of 4-byte NUID. | Required where deterministic single-card identification is mandated (e.g., audit-trail systems, government IDs). | Select MF1S7001XDUF/V1 when UID uniqueness is required for backend reconciliation; MF1S7031XDUF/V1 reduces cost where NUID suffices. |
| MF1S7030XDA4/V1 | MOA4 plastic leadless module (SOT500-2) with same 4-byte NUID, but pre-packaged with antenna interface and tape-and-reel delivery. | Suitable for direct PCB assembly without wafer-level bonding; eliminates custom antenna design and die attach process. | Choose MF1S7030XDA4/V1 for rapid prototyping or low-volume module integration; MF1S7031XDUF/V1 targets high-volume embedded module manufacturing. |
Compared with MF1S7001XDUF/V1, MF1S7031XDUF/V1 trades UID uniqueness for lower unit cost and wafer-thickness optimization (75 μm), while MF1S7030XDA4/V1 shifts from bare die to ready-to-mount module - affecting BOM count, assembly complexity, and antenna co-design requirements.

FAQ
What is the primary function of the MF1S7031XDUF/V1?
The MF1S7031XDUF/V1 is a contactless smart card IC compliant with ISO/IEC 14443 Type A, providing 4 kB of EEPROM memory, CRYPTO1-based mutual authentication, and hardware-accelerated value operations. Its core function is secure credential storage and transaction execution in tap-and-go applications such as transit tickets and access cards - all powered wirelessly from the reader field.
How does the 4-byte NUID in MF1S7031XDUF/V1 differ from the 7-byte UID in other MIFARE Classic variants?
The MF1S7031XDUF/V1 uses a 4-byte Non-Unique ID (NUID), meaning the identifier is not globally unique and may collide in multi-card environments. Unlike the 7-byte UID version (e.g., MF1S7001XDUF/V1), NUID requires application-layer handling of collisions during anticollision - making it suitable for closed-system deployments where backend reconciliation doesn't depend on absolute ID uniqueness.
Can MF1S7031XDUF/V1 be used without external components?
Yes. The MF1S7031XDUF/V1 integrates a complete RF front-end - including rectifier, voltage regulator, clock regenerator, and POR - and requires only an external antenna coil connected between LA and LB terminals. No capacitors, resistors, or additional ICs are needed, enabling minimal bill-of-materials for contactless card or tag designs.
What memory organization does MF1S7031XDUF/V1 use, and how is access controlled?
The MF1S7031XDUF/V1 organizes its 4 kB EEPROM into 40 sectors: 32 sectors of 4 blocks and 8 sectors of 16 blocks, with each block holding 16 bytes. Access is controlled per sector via a trailer block containing two 48-bit keys (A mandatory, B optional) and 3-byte access bits that define read/write/increment permissions for each block type - enforced by hardware before any operation.
Is MF1S7031XDUF/V1 compatible with existing MIFARE Classic reader infrastructure?
Yes. The MF1S7031XDUF/V1 implements the full MIFARE Classic EV1 protocol stack - including ISO/IEC 14443A framing, REQA/WUPA/SELECT commands, CRYPTO1 authentication, and MIFARE-specific read/write/increment commands - ensuring seamless interoperability with legacy and current-generation MIFARE readers without firmware updates.
