Product details
Overview
MF1SEP1001DUD/03V from NXP Semiconductors is a contactless smart card IC designed for seamless migration from MIFARE Classic 1K systems. It delivers 1 kB EEPROM, full MIFARE Classic value-block support, AES-128 authentication in Security Level 3, and linear memory compatibility with MIFARE Classic - enabling secure pre-issuance in legacy infrastructure for public transport and access control applications.
For engineers reviewing the MF1SEP1001DUD/03V datasheet, MF1SEP1001DUD/03V pinout, MF1SEP1001DUD/03V application, or MF1SEP1001DUD/03V equivalent, this page provides verified technical context, security-level-specific command behavior, UID configuration options (7-byte UID), input capacitance (17 pF), and anti-tearing mechanisms for AES key updates - all critical for system-level interoperability and personalization planning.
Technical Context
The MF1SEP1001DUD/03V implements dual-protocol operation: backwards-compatible ISO/IEC 14443-3-based communication in Security Levels 0 and 1 (supporting MIFARE Classic commands), and mandatory ISO/IEC 14443-4 (T=CL) in Security Level 3. It uses a fixed 16-sector × 4-block memory layout (1 kB total), with sector trailers storing CRYPTO1 keys (2 × 48-bit) or AES keys (2 × 128-bit) depending on security level.
Security Level switching is irreversible (0 → 1 → 3) and requires dedicated AES keys (Card Configuration Key, Card Master Key, Level 3 Switch Key). In SL3, all data transactions use session-key-derived MACs for integrity and AES encryption for confidentiality, with multi-sector authentication enabled when sectors share identical keys - reducing authentication overhead across distributed data.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory | 1 kB EEPROM organized as 16 sectors × 4 blocks (16 bytes/block); supports binary data and value-block operations (Increment/Decrement/Transfer). |
| Security Levels | Three levels: SL0 (pre-personalization), SL1 (MIFARE Classic 1K compatibility + optional AES auth), SL3 (AES-128 3-pass auth, encrypted/MACed commands/responses). |
| UID Support | 7-byte UID (fixed, write-protected at production); Random ID configurable in SL3 via Virtual Card Support Last command. |
| Input Capacitance | 17.0 pF typical at 13.56 MHz / 2.8 V RMS - matches antenna tuning requirements of standard MIFARE reader designs. |
| Write Endurance | 200,000 typical single-write cycles (excluding anti-tearing protected AES key/sector trailer writes in SL3). |
| Data Retention | 10 years at 22 °C - ensures long-term validity of stored credentials without refresh. |
| Communication Speed | Up to 848 kbit/s - enables fast transaction throughput in high-volume transit or access scenarios. |
Pinout & Package
MF1SEP1001DUD/03V is supplied in FFC (Film Frame Carrier) wafer format: 8-inch sawn wafer, 120 µm thickness, electronic fail die marking per SECS-II. No bond pads or terminals are exposed; it is a bare die intended for embedding into contactless smart cards or modules. Antenna interface is via LA/LB bonding pads - not user-accessible pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LA | Antenna coil connection A | RF energy harvesting and bidirectional 13.56 MHz communication path; requires external antenna matching network. |
| LB | Antenna coil connection B | Completes resonant LC tank with LA; defines coupling efficiency and read range in final card construction. |
Key Features
| Feature | Design Value |
|---|---|
| Virtual Card Concept | Enables UID retrieval via Virtual Card Support Last command when Random ID is active - essential for SL3 systems requiring UID-based backend reconciliation. |
| Multi-Sector Authentication | Single authentication grants access to multiple sectors sharing identical AES keys - reduces transaction latency in multi-zone access or fare systems. |
| NXP Originality Check | AES-based authentication using factory-programmed originality key verifies genuine NXP silicon - prevents counterfeit card integration. |
| Anti-Tearing for AES Keys | Hardware-enforced atomic update of AES keys and sector trailers in SL3 - guarantees EEPROM consistency even if RF field is interrupted mid-write. |
| Freely Configurable Access Conditions | Per-sector access bits define read/write permissions for keys A/B and data blocks - supports granular privilege separation across applications on one card. |
Applications
| Public Transportation | Access Management |
|---|---|
Use Scenario: Contactless tap-in/tap-out fare collection across buses, trams, and metro gates. IC Role / Device Role / Timing Role: Secure credential storage and SL3-authenticated value-block transactions (e.g., balance decrement) with tamper-proof MAC verification. Use Value: Enables backward compatibility with existing MIFARE Classic readers during phased infrastructure upgrade while enforcing AES-level security for new card issuance. |
Use Scenario: Multi-door enterprise access control with role-based zone permissions. IC Role / Device Role / Timing Role: Stores encrypted access profiles and executes SL3-secured read/write operations for credential validation and audit logging. Use Value: Supports multi-sector authentication across departments - single SL3 auth unlocks all assigned zones, eliminating repeated authentication delays. |
| Electronic Toll Collection | School & Campus Cards |

Use Scenario: Unified student ID for library access, cafeteria payments, and lab entry. IC Role / Device Role / Timing Role: Hosts multiple independent value blocks (cafeteria, printing, lab credits) with distinct access conditions per service. Use Value: Freely configurable access bits allow segregated budget controls - e.g., cafeteria funds cannot be transferred to lab accounts - enforced at hardware level. |
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 |
|---|---|---|---|
| MF1ICS50 | MIFARE Classic 1K IC with CRYPTO1 only; no AES support or SL3 capability; 1 kB EEPROM, 4-byte UID. | Limited to legacy-only deployments; lacks migration path to AES security or SL3 features like MACed commands. | Select when upgrading infrastructure is not planned and cost sensitivity outweighs future-proofing needs. |
| MF1PLUSX0Y1 | MIFARE Plus X-series with extended SL3 functionality (e.g., dynamic key derivation, enhanced PPS support); same 1 kB EEPROM but higher input capacitance (70 pF). | Better suited for greenfield SL3-only systems requiring advanced protocol flexibility; incompatible with classic-reader fallback mode. | Select for new SL3-native deployments where antenna tuning can accommodate 70 pF and infrastructure supports full T=CL feature set. |
Compared with MF1ICS50, MF1SEP1001DUD/03V adds irreversible SL3 migration and AES-128 security while retaining MIFARE Classic interoperability; compared with MF1PLUSX0Y1, it prioritizes cost-effective transition over advanced SL3 extensions, with lower 17 pF input capacitance easing antenna design in retrofit installations.

FAQ
What security levels does MF1SEP1001DUD/03V support, and how do they differ?
MF1SEP1001DUD/03V supports three security levels: SL0 (initial personalization), SL1 (MIFARE Classic 1K compatibility with optional AES authentication), and SL3 (mandatory AES-128 3-pass authentication, encrypted/MACed commands). Migration is irreversible (0→1→3), and SL3 disables backwards compatibility protocol - requiring ISO/IEC 14443-4. Each level defines distinct key storage formats, command sets, and integrity mechanisms, with MF1SEP1001DUD/03V enabling phased infrastructure upgrades.
Does MF1SEP1001DUD/03V support both 4-byte and 7-byte UIDs?
No - MF1SEP1001DUD/03V is specifically ordered with a 7-byte UID (per Table 2 ordering information). The /03V suffix and FFC package variant confirm 7-byte UID configuration. While the MIFARE Plus SE family offers 4-byte NUID variants (e.g., MF1SEP1031DUD/03), MF1SEP1001DUD/03V contains a globally unique 7-byte UID programmed and write-protected at production, ensuring unambiguous identification in multi-application systems.
How is AES key storage implemented in MF1SEP1001DUD/03V?
In MF1SEP1001DUD/03V, AES keys are stored "on top" of the main 1 kB EEPROM - outside the visible memory map - and accessed via Key Number references. Each sector supports two 128-bit AES keys. During SL3 operation, anti-tearing protection ensures atomic updates of these keys and sector trailers, preserving EEPROM state even if power (RF field) is lost mid-write. Keys are written using the Write Perso command in SL0 and activated via Commit Perso to enter SL1 or SL3.
Can MF1SEP1001DUD/03V be used in systems requiring Random ID functionality?
Yes - MF1SEP1001DUD/03V supports Random ID in Security Level 3. When enabled, the PICC responds to the first anticollision loop with a 3-byte random number instead of the fixed UID. The full 7-byte UID can then be retrieved using the Virtual Card Support Last command or by reading block 0. This feature enhances privacy in high-density environments (e.g., stadiums) while maintaining backend traceability through the virtual card concept.
What is the significance of the 17 pF input capacitance specification for MF1SEP1001DUD/03V?
The 17 pF typical input capacitance (measured at 13.56 MHz / 2.8 V RMS) directly determines antenna tuning requirements for MF1SEP1001DUD/03V-based cards. It ensures optimal impedance matching with standard MIFARE reader antennas designed for ~15–19 pF loads, maximizing coupling efficiency and read range. This value - lower than the 70 pF variant (MF1SEPH1001DUD/03) - simplifies retrofit into existing MIFARE Classic infrastructure without antenna redesign.
