NXP Semiconductors MF0AES2001DUDZ

Overview

MF0AES2001DUDZ 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, offers 144-byte user memory in 36 pages of 4 bytes each, supports ISO/IEC 14443-A compliance, and delivers up to 10 cm read range-deployed in public transport tickets, event access passes, and hospitality guest cards.

For engineers reviewing the MF0AES2001DUDZ datasheet, MF0AES2001DUDZ pinout, MF0AES2001DUDZ application, or MF0AES2001DUDZ equivalent, this page details its RF interface architecture, AES-secured memory access model, UID/Random ID state transitions, and bare-die antenna interface requirements for secure, high-volume ticketing system integration.

Technical Context

The MF0AES2001DUDZ integrates an AES coprocessor, TRNG, and command interpreter to execute 3-pass mutual authentication using configurable 128-bit keys (DataProtKey and UIDRetrKey), enabling selective access to protected memory pages and one of three 24-bit counters. Its RF interface complies fully with ISO/IEC 14443-3A and supports 106 kbit/s data transfer with 16-bit CRC, parity, and bit coding for robust communication.

It operates at 13.56 MHz with 17 pF input capacitance (per ordering code DUD), supports double-size 7-byte UID and optional Random ID (RID), and implements anti-tearing logic for counter and lock-bit integrity during interrupted programming cycles-critical for field-deployed disposable credentials.

Key Specifications

Pinout & Package

MF0AES2001DUDZ is supplied as a bare die on Film Frame Carrier (FFC), 120 µm thickness, requiring direct wire bonding to antenna coil terminals. No external power supply or digital I/O pins are present-energy and data are delivered contactlessly via LA/LB connections only.

FAQ

What is the input capacitance specification for MF0AES2001DUDZ?

The MF0AES2001DUDZ has a fixed 17 pF input capacitance, optimized for integration into compact antenna structures used in thin smart cards and key fobs. This value eliminates the need for external tuning capacitors and ensures stable resonance at 13.56 MHz across varying antenna geometries and field strengths-directly supporting the 10 cm maximum read distance specified in the datasheet.

Does MF0AES2001DUDZ support Random ID (RID), and how is it enabled?

Yes, MF0AES2001DUDZ supports optional Random ID (RID) per ISO/IEC 14443-3 to enhance user privacy. RID is enabled by configuring the LOCK_USR_CFG bit in the user configuration area while the IC is in TRACEABLE or AUTHENTICATED state. Once activated, the IC responds with a 4-byte random identifier instead of the permanent 7-byte UID during anti-collision-requiring AES authentication with UIDRetrKey to retrieve the original UID.

How does the AES authentication process work on MF0AES2001DUDZ?

MF0AES2001DUDZ implements a 3-pass mutual authentication protocol using AES-128. The reader sends a challenge, the IC responds with an encrypted nonce, and the reader verifies authenticity before granting access to protected memory pages or counters. Two distinct keys-DataProtKey (for memory access) and UIDRetrKey (for UID retrieval)-are stored in dedicated configuration pages (30h–37h) and enforced via state transitions into AUTHENTICATED or TRACEABLE mode.

What memory organization does MF0AES2001DUDZ use, and how is user memory protected?

MF0AES2001DUDZ organizes its 240-byte EEPROM into 60 pages of 4 bytes each, with 144 bytes allocated as user-programmable memory (pages 04h–27h). Protection is implemented via field-programmable lock bits: per-page locking for the first 16 pages (0–15), and per-two-page locking above that. AES authentication can be configured to restrict access to specific pages or one of three 24-bit counters-enforced only after successful mutual authentication.

Is MF0AES2001DUDZ compliant with NFC Forum Tag Type 2 specifications?

Yes, MF0AES2001DUDZ can be configured to comply with NFC Forum Tag Type 2 technical specifications. This enables NDEF message formatting and interoperability with standard NFC readers and Android/iOS devices. Configuration requires setting appropriate control bits in the configuration pages and enabling the FAST_READ command to support efficient NDEF record parsing-without compromising AES security features or memory protection mechanisms.
