Product details
Overview
MF1S5031XDUD,005 from NXP Semiconductors is a contactless smart card IC compliant with ISO/IEC 14443 Type A, implementing the MIFARE Classic 1K architecture. It features 1 kB EEPROM organized in 16 sectors, 13.56 MHz RF interface, mutual three-pass authentication, and 4-byte non-unique ID (NUID) for cost-sensitive transit and access systems.
For engineers reviewing the MF1S5031XDUD,005 datasheet, MF1S5031XDUD,005 pinout, MF1S5031XDUD,005 application, or MF1S5031XDUD,005 equivalent, key selection considerations include NUID-based anticollision handling, sector-level key A/B access control, 10-year data retention, 100,000 write endurance, and <100 ms typical transaction time in public transport ticketing deployments.
Technical Context
The MF1S5031XDUD,005 integrates an RF interface compliant with ISO/IEC 14443A, a CRYPTO1 stream cipher for authentication and encrypted communication, and a digital control unit managing anticollision, sector selection, and value-block arithmetic operations. Its antenna interface requires no external components beyond the coil.
It operates without onboard power supply-energy is harvested from the 13.56 MHz carrier field-and supports full memory operations (read/write/increment/decrement/transfer/restore) only after successful authentication using keys stored in sector trailers. The 4-byte NUID variant uses non-unique identifiers, requiring system-level collision resolution and avoiding UID-dependent security assumptions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1 kB EEPROM, organized as 16 sectors × 4 blocks (16 bytes/block), enabling multi-application partitioning with per-sector access control. |
| RF Interface | ISO/IEC 14443 Type A compliant at 13.56 MHz, supporting up to 106 kbit/s data transfer and contactless energy harvesting. |
| Identifier | 4-byte Non-Unique ID (NUID); not guaranteed globally unique-requires application-layer handling of duplicate IDs during anticollision. |
| Authentication | Mutual three-pass authentication per ISO/IEC DIS 9798-2 using CRYPTO1 cipher; two keys (A/B) per sector enforce hierarchical access control. |
| Data Integrity | 16-bit CRC per block, odd parity per byte, bit counting, and bit coding ensure robust error detection in noisy RF environments. |
| Endurance & Retention | 100,000 write cycles and 10-year data retention at 22 °C-sufficient for multi-year transit card lifecycle without refresh. |
| Transaction Time | Typical full ticketing transaction (<100 ms) includes anticollision, selection, authentication, and memory operation-critical for high-throughput fare gates. |
Pinout & Package
MF1S5031XDUD,005 is supplied as a bumped die on 8-inch wafer (120 μm thickness, film frame carrier), intended for integration into contactless modules (e.g., MOA4/MOA8). It has no conventional pins; electrical connection is made via two gold bumps: LA and LB, serving as bidirectional antenna coil terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LA | Antenna coil connection A | RF input/output terminal for half-bridge coupling to reader field; forms resonant LC tank with external antenna coil. |
| LB | Antenna coil connection B | Complementary RF terminal completing antenna interface; no DC bias or voltage reference-pure AC-coupled RF path. |
Key Features
| Feature | Design Value |
|---|---|
| Value Block Support | Enables electronic purse functions (increment/decrement/transfer/restore) with built-in backup management and triple-value storage for integrity. |
| Programmable Access Conditions | Per-sector trailer defines read/write/auth permissions for keys A and B-supports multi-application cards with isolated data domains. |
| No External Components Required | Integrated voltage regulator, POR, clock regenerator, and rectifier eliminate need for discrete power or timing components in module design. |
| Fast Anticollision | Intelligent algorithm resolves multiple cards in field within ~2.5 ms (no collision) + ~1 ms per collision-enables dense-reader environments like bus validators. |
| Manufacturer Block Protection | Block 0 (sector 0) contains factory-programmed IC data and is permanently write-protected-ensures traceability and prevents tampering. |
Applications
| Public Transport Ticketing | Access Management |
|---|---|

IC Role / Device Role / Timing Role: Hosts separate applications across 16 sectors-each with independent keys and access conditions-preventing cross-application privilege escalation. Use Value: Allows centralized credential issuance and revocation per application domain without compromising other services on same card. |
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 |
|---|---|---|---|
| MF1S5001XDUD | 7-byte unique UID instead of 4-byte NUID; identical memory map, crypto, and timing. | Required where system-level uniqueness is mandatory (e.g., audit-trail critical transit systems). | Select MF1S5001XDUD when deterministic UID collision avoidance is required; avoid MF1S5031XDUD,005 in such deployments. |
| MF1S5030XDA4 | Same 4-byte NUID and memory spec, but packaged in MOA4 plastic leadless module (SOT500-2) rather than bumped wafer. | Used when module-level assembly (not bare-die embedding) is preferred for faster prototyping or lower assembly complexity. | Choose MF1S5030XDA4 for plug-and-play module integration; MF1S5031XDUD,005 suits custom antenna embedding in thin-form-factor cards. |
Compared with MF1S5001XDUD, the MF1S5031XDUD,005 trades UID uniqueness for lower cost and simplified personalization, while MF1S5030XDA4 offers identical NUID functionality in a ready-to-mount package-making MF1S5031XDUD,005 optimal for high-volume, wafer-level embedded designs where UID uniqueness is managed at system level.

FAQ
What is the identifier type used by MF1S5031XDUD,005?
The MF1S5031XDUD,005 implements a 4-byte Non-Unique ID (NUID), not a globally unique identifier. This means multiple units may share the same ID value, requiring application-layer handling of collisions during anticollision and selection. Unlike the 7-byte UID variants (e.g., MF1S5001XDUD), the NUID does not guarantee uniqueness and must be treated as a functional handle-not a cryptographic identity-in system design.
Does MF1S5031XDUD,005 support value-block operations like increment and decrement?
Yes, MF1S5031XDUD,005 fully supports value-block operations-including increment, decrement, restore, and transfer-when configured with appropriate access conditions in the sector trailer. These operations are executed securely within the IC's internal data register and benefit from triple-value storage and backup management to prevent corruption during power loss or RF interruption.
How is power supplied to MF1S5031XDUD,005 during operation?
MF1S5031XDUD,005 is a passive contactless IC that derives all operating power from the 13.56 MHz electromagnetic field generated by the reader. It contains an integrated rectifier and voltage regulator-no external power source, battery, or capacitor is required. Energy harvesting enables maintenance-free, ultra-thin card form factors ideal for transit and ID applications.
What memory organization does MF1S5031XDUD,005 use?
MF1S5031XDUD,005 organizes its 1 kB EEPROM into 16 sectors, each containing 4 blocks of 16 bytes. Sector 0 includes a manufacturer-programmed, read-only block 0 (with NUID), while sectors 1–15 provide full user programmability. Each sector's trailer block holds keys A/B and access bits-defining granular read/write/auth permissions per block.
Is MF1S5031XDUD,005 compatible with standard ISO/IEC 14443A readers?
Yes, MF1S5031XDUD,005 is fully compliant with ISO/IEC 14443 Type A at the physical, RF, and protocol layers-including ATQA/SAK responses, REQA/WUPA commands, and frame timing. It interoperates with any certified ISO/IEC 14443A reader, though application-level behavior (e.g., NUID handling) must align with system firmware expectations.
