Product details
Overview
MF0ICU1001W/U7DL from NXP Semiconductors is a contactless single-ticket IC compliant with ISO/IEC 14443 A, designed for low-cost paper-based smart tickets in public transport and event access. It features 512-bit EEPROM (16 pages × 4 bytes), 7-byte cascaded UID, field-programmable per-page read-only locking, and 32-bit OTP area. Its 17 pF on-chip resonance capacitor supports TFC.0 (Edmondson) ticket formats.
For engineers reviewing the MF0ICU1001W/U7DL datasheet, MF0ICU1001W/U7DL pinout, MF0ICU1001W/U7DL application, or MF0ICU1001W/U7DL equivalent, this page delivers verified technical context, memory architecture details, anticollision behavior, RF interface timing, and real-world integration constraints for ticket vending equipment and PCD-compatible systems.
Technical Context
The MF0ICU1001W/U7DL implements a fully ISO/IEC 14443-3 A-compliant RF interface with 13.56 MHz carrier, 106 kbit/s data rate, and integrated rectifier, clock regenerator, POR, and voltage regulator - requiring no external components beyond the antenna coil. Its digital control unit executes a deterministic state machine (Idle → Ready 1 → Ready 2 → Active → Halt) governed by REQA/WUPA/ANTICOLLISION/SELECT/READ/WRITE/HALT commands.
Memory access follows strict page-level protocols: READ returns 16 bytes starting at specified page address with wraparound; WRITE programs 4 bytes per command; COMPATIBILITY WRITE accepts 16-byte input but writes only LSB 4 bytes. Locking is irreversible - setting lock bits Lx or block-lock bits BLx via WRITE to page 02h permanently disables further writes to corresponding pages 03h–0Eh.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Standard | ISO/IEC 14443 A - ensures interoperability with global PCD infrastructure and legacy MIFARE readers |
| Operating Frequency | 13.56 MHz - defines resonant coupling with reader antenna and determines coil design constraints |
| EEPROM Size | 512 bits (16 × 4-byte pages) - provides 384-bit user R/W area (pages 04h–0Fh), 32-bit OTP (page 03h), and UID/lock storage |
| Input Capacitance | 17 pF - matches TFC.0 (Edmondson) ticket format; enables direct integration into 6-turn coil paper tickets without external tuning capacitors |
| Data Retention | 5 years at 22 °C - guarantees validity of stored ticket data across typical transit pass lifecycles |
| Write Endurance | 10,000 cycles - supports multi-trip validation, counter updates, or limited reprogramming in day-pass applications |
| Transaction Time | < 35 ms typical ticketing transaction - meets real-time fare gate throughput requirements under anticollision conditions |
Pinout & Package
MF0ICU1001W/U7DL is supplied as a bare die in FFC (Film Frame Carrier) format, 120 µm thickness, Au bumps, on 8-inch wafer. It has no conventional pins; electrical connection is made exclusively via two antenna bonding pads: LA and LB. These pads interface directly with the printed coil antenna embedded in paper or plastic tickets - no PCB, soldering, or wire bonding required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LA | Antenna coil connection A | Primary terminal for resonant LC tank formation; connects to one end of the etched or printed coil |
| LB | Antenna coil connection B | Secondary terminal completing the LC tank; impedance matching and energy harvesting depend on LA–LB parasitic capacitance and coil inductance |
Key Features
| Feature | Design Value |
|---|---|
| Cascaded UID (7-byte) | Enables ISO/IEC 14443-3 cascade level 2 anticollision - allows simultaneous presence of multiple tickets in reader field without communication failure |
| Field-programmable per-page lock | Irreversible write-protection per memory page (03h–0Eh) via WRITE to page 02h - secures OTP configuration and prevents tampering with ticket balance or access rights |
| 32-bit One-Time Programmable area | Page 03h pre-initialized to 00h; bitwise OR programming allows permanent encoding of unique keys, serial extensions, or cryptographic seeds |
| 17 pF on-chip resonance capacitor | Eliminates need for external capacitor in TFC.0 ticket designs - reduces bill-of-materials and simplifies antenna layout for compact paper-based tickets |
| Typical operating distance | Up to 100 mm (dependent on antenna geometry and reader power) - supports hands-free validation at turnstiles and handheld validators |
Applications
| Public Transit Fare Collection | Event Access Control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless single-ticket IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MF0ICU1001W/S7DL | Same die, 75 µm thickness, 17 pF capacitance, but delivered on film frame carrier with 75 µm wafer thickness | Better suited for ultra-thin laminated cards where mechanical flex resistance is critical | Select MF0ICU1001W/S7DL when integrating into rigid PVC cards or thin-film laminates requiring higher bending endurance |
| MF0ICU1101W/U7DL | Same package and wafer specs, but 50 pF on-chip capacitance instead of 17 pF | Optimized for TFC.1 (ISO) ticket formats with larger coil geometries; incompatible with TFC.0 antenna layouts | Choose MF0ICU1101W/U7DL only when designing for ISO-standard sized tickets with ≥50 pF antenna resonance requirement |
Compared with MF0ICU1001W/U7DL, MF0ICU1001W/S7DL offers identical electrical functionality but improved mechanical robustness for thin-card applications, while MF0ICU1101W/U7DL shifts resonance to 50 pF - making it unsuitable for TFC.0 paper tickets unless antenna redesign is performed.

FAQ
What is the primary mechanical form factor of MF0ICU1001W/U7DL?
MF0ICU1001W/U7DL is supplied as a bare die on an 8-inch wafer in FFC (Film Frame Carrier) format, with 120 µm thickness and Au bumps. It has no leadframe or molded package - intended for direct flip-chip bonding onto antenna substrates in paper or plastic tickets.
Does MF0ICU1001W/U7DL require external components for RF operation?
No. MF0ICU1001W/U7DL integrates a 17 pF resonance capacitor and requires only a printed or etched coil connected between LA and LB pads. No external capacitors, resistors, or regulators are needed - enabling true single-component integration into low-cost tickets.
How does the locking mechanism work in MF0ICU1001W/U7DL?
Locking is performed by writing to page 02h: bits L0–L15 individually disable writes to pages 03h–0Eh, while block-lock bits BLOTP, BL9-4, and BL15-10 freeze further lock configuration changes. All lock operations are irreversible - once a bit is set to logic 1, it cannot be reset.
What is the difference between MF0ICU1001W/U7DL and MF0ICU1101W/U7DL?
MF0ICU1001W/U7DL features 17 pF on-chip capacitance for TFC.0 (Edmondson) ticket formats, whereas MF0ICU1101W/U7DL uses 50 pF capacitance for TFC.1 (ISO) formats. They share identical package, wafer thickness, and bump specs - only resonance capacitance differs.
Can MF0ICU1001W/U7DL be used in ISO/IEC 14443 B systems?
No. MF0ICU1001W/U7DL is strictly compliant with ISO/IEC 14443 A - including modulation scheme, protocol timing, and command set (REQA/WUPA/ANTICOLLISION/SELECT/READ/WRITE). It does not support ISO/IEC 14443 B carrier modulation or command structure.
