Product details
Overview
MF0AES2001DUFZ from NXP Semiconductors is a contactless smart IC designed for limited-use ticketing and RFID key cards managed by a single entity. It implements AES-128 mutual authentication, provides 144-byte user memory organized in 36 pages of 4 bytes each, supports ISO/IEC 14443-A at 13.56 MHz, and delivers up to 10 cm read range. It serves public transport ticketing systems requiring secure, low-cost, disposable credentials.
For engineers reviewing the MF0AES2001DUFZ datasheet, MF0AES2001DUFZ pinout, MF0AES2001DUFZ application, or MF0AES2001DUFZ equivalent, this page details its RF interface compliance, memory protection architecture, UID/Random ID behavior, counter security model, and bare-die antenna interface requirements for integration into tags, wristbands, or fobs.
Technical Context
The MF0AES2001DUFZ integrates an AES coprocessor, TRNG, and EEPROM interface within a fully ISO/IEC 14443-A compliant RF front-end operating at 13.56 MHz with 106 kbit/s data rate. Its digital control unit enforces state-based access (IDLE → READY1 → ACTIVE → AUTHENTICATED) and supports three independent 24-bit one-way counters - one configurable for AES-authenticated access.
It features dual input capacitance options (17 pF standard), implemented here as a 75 µm-thick bare die on Film Frame Carrier (FFC), with LA/LB antenna terminals only - no power or logic pins. Memory includes 32-bit OTP, field-programmable per-page lock bits for first 16 pages, and block-wise lock for higher addresses, plus pre-programmed ECC-based originality signature verifiable via READ_SIG.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
MF0AES2001DUFZ is supplied as a 75 µm-thick bare die on Film Frame Carrier (FFC), intended for embedding into inlay antennas. It has no conventional IC package or logic pins - only two RF terminals for direct coil connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| LA | Antenna coil connection (low-side) | Direct bond pad for one end of planar antenna loop; forms resonant LC tank with internal 17 pF capacitance. |
| LB | Antenna coil connection (high-side) | Direct bond pad for opposite end of antenna loop; completes RF energy harvesting and bidirectional data coupling path. |
| GND | Ground Pin | Internally disconnected - not bonded or used; no external grounding required for operation. |
| TEST | Test Pin | Internally disconnected - reserved for wafer-level testing only; left floating in final application. |
Key Features
| Feature | Design Value |
|---|---|
| ISO/IEC 14443-A Compliance | Full protocol stack implementation enabling plug-and-play integration with existing transit gates, NFC readers, and mobile devices. |
| Configurable Random ID (RID) | Enables GDPR-compliant privacy mode: real 7-byte UID masked until AES-authenticated, preventing passive tracking. |
| Fast Read Command | Reads entire 144-byte user memory in one RF frame - reduces transaction time in high-throughput ticket personalization lines. |
| ECC-Based Originality Signature | Verifiable via READ_SIG command to detect counterfeit ICs; supports customer-specific signature overwrite during personalization. |
| Anti-Tearing Protection | Hardware-enforced atomicity for counter updates and lock-bit programming - prevents corruption during RF field dropout. |
Applications
| Public Transport Ticketing | Hospitality Guest Cards |
|---|---|
|
Use Scenario: Disposable single-journey or day-pass tickets issued at kiosks or mobile apps for metro/bus networks. IC Role / Device Role / Timing Role: Secure credential storage and authentication endpoint; validates ride entitlement and logs usage via protected counters. Use Value: Prevents reuse or cloning via AES-128 mutual auth and UID verification, while 10 cm read range enables fast platform validation. |
Use Scenario: Hotel room key cards issued at front desk with limited validity and revocable access rights. IC Role / Device Role / Timing Role: Tamper-resistant identity token storing encrypted room number, check-in time, and expiry date. Use Value: Enables AES-protected memory writes during issuance and Fast Read for instant door lock verification without backend dependency. |
| Event Access Control | Loyalty Voucher Redemption |
|
Use Scenario: NFC-enabled wristbands or paper tickets for concerts/festivals with timed entry and session validation. IC Role / Device Role / Timing Role: Session gatekeeper using authenticated READ_CNT to enforce entry limits and prevent duplicate scanning. Use Value: One-way counters protected by optional AES auth ensure each scan consumes a valid entry slot, even offline. |
Use Scenario: Promotional vouchers distributed digitally or printed with embedded NFC tag for point-of-sale redemption. IC Role / Device Role / Timing Role: Encrypted payload carrier storing voucher code, merchant ID, and remaining balance in protected pages. Use Value: OTP area stores immutable terms; CMAC-secured responses prevent man-in-the-middle tampering during POS verification. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless limited-use IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MF0ULX2001DUF | No AES engine; uses legacy 3DES or no crypto; 48-byte user memory; lacks CMAC, RID, and originality signature. | Suitable for cost-sensitive, non-security-critical applications like basic access badges with no counter or encryption needs. | Select when AES-128, 144-byte memory, or anti-counterfeiting are not required - lower BOM cost but reduced security posture. |
| MF3ICD40 | Higher security: Common Criteria EAL5+, supports DESFire EV3 applets, 2 KB EEPROM, AES-128/192/256, and diversified keys. | Targeted at multi-application, reusable credentials (e.g., corporate ID + transit + payment) requiring dynamic applet loading. | Choose when infrastructure supports DESFire EV3, and long-term reusability, applet flexibility, or stronger certification (EAL5+) is mandatory. |
Compared with MF0ULX2001DUF, MF0AES2001DUFZ adds AES-128, 3× more memory, and hardware anti-tearing - making it fit for mid-tier secure ticketing. Against MF3ICD40, it trades applet support and CC EAL5+ for lower cost, smaller footprint, and faster throughput in single-purpose deployments.

FAQ
What is the input capacitance of MF0AES2001DUFZ and why does it matter?
The MF0AES2001DUFZ has a fixed 17 pF input capacitance, optimized for standard MIFARE Ultralight antenna designs used in thin tickets and smart cards. This value determines the resonant frequency with the external antenna coil - matching it ensures maximum RF energy harvesting efficiency and consistent 10 cm read range across production units.
Does MF0AES2001DUFZ support Random ID (RID), and how is it enabled?
Yes, MF0AES2001DUFZ supports optional Random ID (RID) per ISO/IEC 14443-3. RID is enabled by setting configuration bits in the CFG_0/CFG_1 pages while in TRACEABLE or AUTHENTICATED state. Once activated, the IC responds with a 4-byte random identifier instead of the permanent 7-byte UID - enhancing user privacy in surveillance-sensitive environments.
How many bytes of user memory does MF0AES2001DUFZ provide, and how is it structured?
MF0AES2001DUFZ provides 144 bytes of user memory, organized in 36 pages of 4 bytes each. Pages 0–3 contain manufacturer data, lock bytes, and 32-bit OTP; pages 4–39 hold freely programmable user data; pages 40–59 include configuration, keys, and RFU space - all accessible via standard READ/FAST_READ commands after proper authentication.
What security certifications apply to MF0AES2001DUFZ?
MF0AES2001DUFZ holds Common Criteria EAL3+ certification (AVA_VAN.2) for basic attack potential, validating its resistance against logical and physical probing under defined threat models. It also implements NIST SP 800-38B-compliant CMAC for message integrity and supports ECC-based originality signature verification to deter counterfeit ICs.
Can MF0AES2001DUFZ be used in NFC Forum Tag Type 2 applications?
Yes, MF0AES2001DUFZ can be configured to comply with NFC Forum Tag Type 2 specification. This allows it to store NDEF messages and interoperate with Android and iOS NFC hosts - enabling smartphone-based ticket issuance, balance checks, or loyalty program enrollment without proprietary reader infrastructure.
