Product details
Overview
MF0UL2101DUD2A from NXP Semiconductors is a contactless smart ticket IC compliant with ISO/IEC 14443 Type A, featuring 1024-bit user memory, 17 pF input capacitance, and 3 independent 24-bit one-way counters. It serves as a secure, low-cost replacement for paper/magnetic tickets in transit and event access systems.
For engineers reviewing the MF0UL2101DUD2A datasheet, MF0UL2101DUD2A pinout, MF0UL2101DUD2A application, or MF0UL2101DUD2A equivalent, key selection criteria include UID authenticity (7-byte manufacturer-programmed), field-programmable page locking, OTP area for ticket state tracking, and <35 ms transaction time in real-world PCD environments.
Technical Context
The MF0UL2101DUD2A integrates an RF interface (13.56 MHz carrier, 106 kbit/s data rate), digital control unit, and 1312-bit EEPROM organized in 41 pages of 4 bytes each. Its memory includes 1024-bit user R/W space, 32-bit OTP, 3×24-bit counters, and configuration pages (25h–28h) for password-protected access control.
It implements true anticollision per ISO/IEC 14443-3 cascade level 2, supports ECC-based originality signature verification, and enforces anti-tearing during counter/OTP/lock-bit writes. The device operates without external components-power and data are coupled via LA/LB antenna terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 1312-bit EEPROM (41 × 4-byte pages); 1024-bit freely programmable user area |
| Input Capacitance | 17 pF - enables compatibility with TFC.0 (Edmondson) and TFC.1 (ISO) ticket formats |
| Operating Frequency | 13.56 MHz - ensures interoperability with global ISO/IEC 14443 Type A readers |
| Data Rate | 106 kbit/s - supports fast ticket validation in high-throughput transit gates |
| UID | 7-byte manufacturer-programmed serial number with two BCC bytes - provides unique, tamper-resistant device identification |
| Write Endurance | 100,000 cycles for EEPROM; 1,000,000 cycles for one-way counters - sustains multi-trip usage over full ticket lifetime |
| Data Retention | 10 years at 22 °C - guarantees validity across seasonal event passes or annual transit subscriptions |
Pinout & Package
MF0UL2101DUD2A is supplied as a bare die (120 μm thickness, Au bumps) on 12-inch wafer in FFC Bump packaging. No leadframe or molded package is present; electrical connection is made exclusively via LA and LB antenna coil terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LA | Antenna coil connection A | RF energy harvesting and bidirectional data coupling node; requires direct bond to tuned loop antenna |
| LB | Antenna coil connection B | Completes resonant LC circuit with LA; no external capacitor needed due to integrated 17 pF resonance capacitance |
Key Features
| Feature | Design Value |
|---|---|
| Field-programmable page locking | Per-page lock bits (pages 03h–0Fh) and 2-page granularity locks (pages 10h–28h) prevent unauthorized rewrites after personalization |
| One-time programmable (OTP) area | 32-bit OTP page (03h) enables irreversible state encoding (e.g., used-ticket flag) using bit-wise OR write semantics |
| True one-way counters | Three independent 24-bit counters support trip counting, session limits, or loyalty point accumulation with 1M-cycle endurance |
| Password-protected memory access | 32-bit PWD + 16-bit PACK authentication secures sensitive fields (e.g., balance, access rights) against casual read/write attempts |
| ECC-based originality signature | Read-only READ_SIG command returns chip-authentic signature - verifies genuine NXP silicon in anti-counterfeiting workflows |
Applications
| Public Transportation Ticketing | Event Access Control |
|---|---|
Use Scenario: Disposable or reloadable single-journey or day-pass tickets validated at subway turnstiles and bus validators. IC Role / Device Role / Timing Role: Contactless ticket IC providing UID, encrypted balance, and counter-based trip validation in <35 ms per transaction. Use Value: Enables offline validation with tamper-resistant UID and OTP-based used-ticket marking, eliminating backend dependency during peak boarding. |
Use Scenario: RFID wristbands or paper tickets granting timed entry to concerts, festivals, or conferences. IC Role / Device Role / Timing Role: Secure credential storage for access rights, session timing, and anti-duplication via ECC signature verification. Use Value: Prevents credential sharing through one-way counters and password-locked access zones, while supporting rapid batch scanning at venue entrances. |
| Loyalty Program Token | Secure ID Badge Extension |
Use Scenario: Low-cost plastic or paper tokens issued to retail customers for point accrual and redemption. IC Role / Device Role / Timing Role: Persistent, field-writable memory IC storing points balance, tier status, and OTP-encoded campaign flags. Use Value: Supports offline point updates via NFC-enabled smartphones, with lock bits preventing balance manipulation after issuance. |
Use Scenario: Supplemental credential embedded in printed ID badges for secondary access layers (e.g., lab entry, restricted zones). IC Role / Device Role / Timing Role: Secondary identity element authenticated via READ_SIG and password-protected configuration pages. Use Value: Adds hardware-rooted authenticity to legacy badge systems without replacing core infrastructure or requiring new reader deployment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless ticket IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MF0UL2101DUD | Identical memory map, 1024-bit user space, and 17 pF capacitance; differs only in wafer size (8-inch vs. 12-inch) and bump layout | No functional difference in end-use ticket performance or integration; identical electrical behavior and timing | Select MF0UL2101DUD2A for volume production requiring 12-inch wafer sourcing and optimized die yield consistency |
| MF0ULH2101DUD | Same 1024-bit memory but 50 pF input capacitance - requires different antenna tuning and supports higher operating distance in constrained-field readers | Better suited for thick-card or embedded-in-metal applications where extended coupling range is critical | Choose MF0ULH2101DUD only when antenna design accommodates higher capacitance; MF0UL2101DUD2A remains optimal for standard paper/inlay tickets |
Compared with MF0UL2101DUD2A, MF0UL2101DUD offers identical functionality with minor wafer logistics differences, while MF0ULH2101DUD trades compatibility with standard antennas for extended operational range - making MF0UL2101DUD2A the preferred choice for cost-sensitive, high-volume transit and event ticketing where TFC.0/TFC.1 form factors dominate.

FAQ
What is the exact memory organization of MF0UL2101DUD2A?
The MF0UL2101DUD2A contains 1312-bit EEPROM organized into 41 pages of 4 bytes each. Pages 00h–02h hold the 7-byte UID and BCC bytes; pages 03h (OTP), 04h–23h (1024-bit user R/W), 24h (lock bytes 2–4), and 25h–28h (configuration) are fully defined. This structure supports secure, field-updatable ticket data with dedicated counter and locking regions.
Does MF0UL2101DUD2A support ISO/IEC 14443 Type A communication?
Yes, MF0UL2101DUD2A is fully compliant with ISO/IEC 14443 Type A, including REQA/WUPA anticollision, cascade level 2 UID selection, and 106 kbit/s data transfer with 16-bit CRC, parity, and bit coding. It operates at 13.56 MHz and requires no external components beyond the LA/LB antenna connections.
How does the password protection mechanism work in MF0UL2101DUD2A?
MF0UL2101DUD2A uses a 32-bit password (PWD) and 16-bit acknowledge (PACK) stored in configuration pages 27h–28h. When AUTH0 is set to a valid page address, subsequent read/write operations to that page and above require successful PWD_AUTH before access. AUTHLIM limits failed attempts to prevent brute-force attacks.
Can MF0UL2101DUD2A be used in paper-based tickets?
Yes, MF0UL2101DUD2A is explicitly designed for inlay and paper ticket manufacturing. Its 17 pF input capacitance matches TFC.0 (Edmondson) and TFC.1 (ISO) formats, and its bare-die FFC Bump packaging allows direct embedding into thin substrates without encapsulation - meeting mechanical and RF requirements for mass-produced disposable tickets.
What is the purpose of the ECC-based originality signature in MF0UL2101DUD2A?
The ECC-based originality signature in MF0UL2101DUD2A is accessed via the READ_SIG command and provides cryptographic proof of genuine NXP silicon. It helps system integrators verify authenticity during personalization or gate validation - mitigating counterfeit ticket risk without requiring complex host-side cryptography.
