Product details
Overview
MF0UL2101DUD,005 from NXP Semiconductors is a contactless ticket IC compliant with ISO/IEC 14443 Type A, featuring 1024-bit user memory, 17 pF input capacitance, 13.56 MHz operating frequency, and 3 independent 24-bit one-way counters - deployed in public transit smart tickets and event day passes.
For engineers reviewing the MF0UL2101DUD,005 datasheet, MF0UL2101DUD,005 pinout, MF0UL2101DUD,005 application, or MF0UL2101DUD,005 equivalent, key selection considerations include UID authenticity verification, field-programmable page locking (per 2 pages above page 15), OTP area configuration, and password-protected memory access for secure ticket personalization.
Technical Context
The MF0UL2101DUD,005 integrates an RF interface (modulator/demodulator, rectifier, clock regenerator, POR, voltage regulator), digital control unit, and 1312-bit EEPROM organized in 41 pages of 4 bytes each. It supports true anticollision per ISO/IEC 14443-3 cascade level 2 and executes full ticketing transactions in under 35 ms.
Its memory architecture includes 1024-bit user R/W area (pages 04h–23h), 32-bit OTP page (03h), 3×24-bit one-way counters, and configuration pages (25h–28h) enabling password-based access control (32-bit PWD, 16-bit PACK) and lock-bit granularity of 2 pages for extended memory sections.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.56 MHz - Enables interoperability with global ISO/IEC 14443 Type A readers used in transit gates and event turnstiles. |
| User Memory Size | 1024 bits (32 pages) - Supports multi-trip fare storage, loyalty points, and dynamic event session data without external memory. |
| Input Capacitance | 17 pF - Matches TFC.0 (Edmondson) and TFC.1 (ISO) ticket formats for reliable antenna coupling in thin paper or PET inlays. |
| One-Way Counters | 3 × 24-bit - Provides tamper-resistant trip counting (e.g., 3-day pass validation) with 1,000,000 write endurance per counter. |
| Data Integrity | 16-bit CRC + parity + bit coding - Ensures error-free communication in noisy RF environments like crowded metro stations. |
| Write Endurance | 100,000 cycles (EEPROM), 1,000,000 cycles (counters) - Guarantees longevity across repeated top-ups or daily validations over 5+ years. |
| UID Format | 7-byte manufacturer-programmed UID + 2 BCC bytes - Enables unique device identification and anti-cloning via ECC-based originality signature. |
Pinout & Package
MF0UL2101DUD,005 is supplied as a bare die (FFC Bump) with 120 μm thickness, Au bumps, and electronic fail die marking per SECS-II format - intended for embedding into antenna inlays or modules. No external pins; direct LA/LB coil connections only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LA | Antenna coil connection A | RF energy harvesting and bidirectional data coupling node - requires impedance-matched loop antenna (e.g., 5–7 turns, ~1 μH). |
| LB | Antenna coil connection B | Completes resonant LC tank with LA; no internal bias or termination - design must ensure symmetrical trace routing to minimize EMI. |
Key Features
| Feature | Design Value |
|---|---|
| Field-programmable page locking | Per 2 pages (pages 10h–28h) - Enables irreversible read-only protection of fare balance or credential data post-issuance. |
| Password-protected memory access | 32-bit PWD + 16-bit PACK in config pages - Allows tiered access control (e.g., read-only balance vs. write-enabled reload) without cryptographic overhead. |
| Anti-tearing support | On OTP, counters, and lock bits - Prevents partial writes during power loss, ensuring atomic state transitions in transit validator timeouts. |
| ECC-based originality signature | Read via READ_SIG command - Verifies chip authenticity against counterfeit inlays, critical for revenue-grade ticketing systems. |
| Fast counter transaction | <10 ms - Enables real-time decrement on entry/exit, meeting sub-100 ms gate throughput requirements in high-traffic hubs. |
Applications
| Public Transit Ticketing | Event Day Passes |
|---|---|

Use Value: Manufacturer-programmed UID + ECC signature blocks cloned tokens; page locking secures admin keys against overwrite. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless ticketing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MF0UL2101DUD2 | Identical electrical specs and memory map; differs only in 12-inch wafer sourcing (vs. 8-inch for MF0UL2101DUD,005) | Same functional use in ticket inlays; suited for high-volume production requiring larger wafer lots | Select MF0UL2101DUD2 when supply chain prioritizes 12-inch wafer availability and long-term volume stability. |
| MF0ULH2101DUD | 50 pF input capacitance (vs. 17 pF); otherwise identical memory, counters, and security features | Optimized for TFC.0 (Edmondson) format only; incompatible with TFC.1 antenna designs due to resonance shift | Choose MF0ULH2101DUD only when integrating into legacy Edmondson-format paper tickets with fixed 50 pF tuning. |
Compared with MF0UL2101DUD,005, MF0UL2101DUD2 offers identical functionality with enhanced wafer-scale supply continuity, while MF0ULH2101DUD trades 17 pF flexibility for 50 pF optimization - making MF0UL2101DUD,005 the default choice for dual-format (TFC.0/TFC.1) inlay designs requiring field-proven compatibility.

FAQ
What is the memory organization of MF0UL2101DUD,005?
The MF0UL2101DUD,005 contains 1312-bit EEPROM organized in 41 pages of 4 bytes each: pages 00h–02h hold UID and manufacturer data; 03h is OTP; 04h–23h provide 1024-bit user R/W memory; 24h holds extended lock bytes; and 25h–28h are configuration pages. This layout supports secure, segmented data storage for transit and event use cases.
Does MF0UL2101DUD,005 support password protection?
Yes, MF0UL2101DUD,005 supports 32-bit password (PWD) and 16-bit password acknowledge (PACK) stored in configuration pages 27h and 28h. Password verification restricts access to memory pages starting from AUTH0-defined address, with optional AUTHLIM to limit failed attempts - implemented for secure ticket personalization.
How does the anticollision function work in MF0UL2101DUD,005?
The MF0UL2101DUD,005 implements ISO/IEC 14443-3 compliant cascade-level 2 anticollision: it responds to REQA/WUPA commands in IDLE/HALT states, resolves its 7-byte UID in READY1/READY2 states, and enters ACTIVE state only after successful SELECT - ensuring reliable multi-card operation in dense reader fields like transit gates.
What is the purpose of the 3 one-way counters in MF0UL2101DUD,005?
The three 24-bit one-way counters in MF0UL2101DUD,005 enable irreversible, tamper-resistant counting for applications like trip validation or session limits. Each counter supports up to 16.7 million increments with 1,000,000 write cycles, and is accessed exclusively via INCR_CNT and READ_CNT commands - preventing accidental or malicious resets.
Is MF0UL2101DUD,005 compatible with existing MIFARE infrastructure?
Yes, MF0UL2101DUD,005 is fully backward-compatible with MIFARE Ultralight systems and interoperable with standard ISO/IEC 14443 Type A readers. Its command set extends MF0ICU1 support while maintaining identical timing and protocol behavior - allowing seamless integration into legacy transit validators and event access systems without firmware changes.
