Product details
Overview
MF0UL1101DUF,005 from NXP Semiconductors is a contactless ticket IC compliant with ISO/IEC 14443 Type A, featuring 640-bit EEPROM (384-bit user memory), 7-byte UID, 3×24-bit one-way counters, and 32-bit OTP area - deployed in public transit single-trip tickets, event day passes, and loyalty tokens.
For engineers reviewing the MF0UL1101DUF,005 datasheet, MF0UL1101DUF,005 pinout, MF0UL1101DUF,005 application, or MF0UL1101DUF,005 equivalent, this page delivers verified electrical specs, antenna interface details, security features (password protection, ECC signature), memory locking behavior, and real-world timing performance (<35 ms transaction).
Technical Context
The MF0UL1101DUF,005 implements a passive RF interface operating at 13.56 MHz with 17 pF on-chip resonance capacitance, enabling compatibility with TFC.0 (Edmondson) and TFC.1 (ISO) ticket formats. Its digital control unit executes anticollision per ISO/IEC 14443-3 cascade levels 1 and 2, supports FAST_READ and INCR_CNT commands, and enforces field-programmable page-level read-only locking.
Memory organization comprises 20 pages × 4 bytes, with UID in pages 0–2, OTP in page 3, user data in pages 4–15, and configuration in pages 16–19. Lock bytes 0–1 (page 2) control per-page write protection for pages 3–15, while anti-tearing support ensures atomic updates to OTP, counters, and lock bits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Interface Standard | ISO/IEC 14443 Type A - enables interoperability with global PCD readers used in transit gates and access terminals |
| Operating Frequency | 13.56 MHz - defines RF carrier frequency for energy harvesting and bidirectional communication |
| EEPROM Capacity | 640-bit total / 384-bit user R/W - provides sufficient space for trip validation, balance storage, and event metadata in disposable tickets |
| Input Capacitance | 17 pF - matches standard antenna designs for TFC.0/TFC.1 paper or inlay tickets without external tuning components |

Pinout & Package
MF0UL1101DUF,005 is supplied as a bare die (75 μm thickness, Au bumps) on an 8-inch wafer in film frame carrier format - intended for direct bonding onto antenna substrates in ticket inlays. No external pins; only two RF terminals interface with the antenna coil.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LA | Antenna coil connection A | RF input terminal for half of series-connected antenna loop; forms resonant tank with internal 17 pF capacitor |
| LB | Antenna coil connection B | RF input terminal for second half of antenna loop; completes passive power harvesting and data coupling path |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless ticketing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MF0UL1101DUD | Same 640-bit memory and 17 pF capacitance, but 120 μm die thickness - optimized for thicker inlay substrates or thermal stress environments | Suitable for laminated cards or embedded modules requiring higher mechanical robustness | Select MF0UL1101DUD when die handling or lamination process demands greater thickness tolerance. |
| MF0ULH1101DUF | Identical 640-bit memory but 50 pF input capacitance - requires antenna redesign for TFC.0/TFC.1 compliance | Enables longer read range in low-coupling environments (e.g., thick wallets or metal-adjacent placements) | Choose MF0ULH1101DUF only if antenna geometry permits 50 pF resonance tuning and extended operating distance is prioritized over drop-in compatibility. |
Compared with MF0UL1101DUF,005, MF0UL1101DUD offers enhanced mechanical durability without altering RF behavior, while MF0ULH1101DUF trades plug-and-play antenna compatibility for extended read range - both require validation against specific inlay stack-up and reader field strength.

FAQ
What is the exact memory structure of MF0UL1101DUF,005?
The MF0UL1101DUF,005 contains 640-bit EEPROM organized into 20 pages of 4 bytes each. Pages 0–2 hold the 7-byte UID and check bytes; page 3 is the 32-bit OTP area; pages 4–15 constitute the 384-bit user R/W memory; and pages 16–19 store configuration data including password (PWD), access control (ACCESS), and virtual card type (VCTID). Lock bytes reside in page 2.
Does MF0UL1101DUF,005 support password protection, and how is it configured?
Yes, MF0UL1101DUF,005 supports 32-bit password protection via the PWD_AUTH command. Protection is enabled by writing a page address (e.g., 04h) to the AUTH0 byte in page 16 - all subsequent memory accesses starting at that page require successful password verification. The default AUTH0 value is FFh, disabling protection until explicitly configured.
What is the operating distance capability of MF0UL1101DUF,005?
The MF0UL1101DUF,005 achieves up to 100 mm operating distance under optimal conditions - dependent on reader antenna size, power output, coil geometry, and environmental factors like nearby metal or water. Its 17 pF input capacitance is tuned for standard TFC.0/TFC.1 antenna layouts used in paper tickets and inlays.
How does the anticollision function work in MF0UL1101DUF,005?
The MF0UL1101DUF,005 implements ISO/IEC 14443-3 compliant anticollision using cascade levels 1 and 2. During REQA/WUPA, multiple devices respond with partial UIDs; the reader resolves collisions by progressively selecting individual devices via SELECT commands. This ensures reliable operation in dense environments like transit gates with stacked tickets.
What security mechanisms prevent cloning of MF0UL1101DUF,005-based tickets?
MF0UL1101DUF,005 incorporates manufacturer-programmed 7-byte UID, ECC-based originality signature (read via READ_SIG), and one-time programmable (OTP) bytes - all resistant to duplication. While password protection adds access control, the ECC signature provides cryptographic proof of genuine NXP silicon, deterring counterfeit inlays.
