NXP Semiconductors MF0AESH2001DUDZ

Overview

MF0AESH2001DUDZ from NXP Semiconductors is a contactless smart IC for limited-use ticketing and RFID key cards, featuring AES-128 mutual authentication, 144-byte user EEPROM, 7-byte UID, and 50 pF input capacitance optimized for key fobs and wristbands. It operates at 13.56 MHz, supports ISO/IEC 14443-A, and delivers up to 10 cm read range in compliant infrastructure.

For engineers reviewing the MF0AESH2001DUDZ datasheet, MF0AESH2001DUDZ pinout, MF0AESH2001DUDZ application, or MF0AESH2001DUDZ equivalent, this page provides verified technical context, memory layout details, security state transitions, NFC Forum Tag 2 Type compliance, and real-world deployment constraints for public transport, event ticketing, hospitality, and loyalty systems.

Technical Context

The MF0AESH2001DUDZ implements a dedicated AES coprocessor with 3-pass mutual authentication using two configurable 128-bit keys (DataProtKey and UIDRetrKey), enabling secure access to protected memory pages and UID retrieval. Its digital control unit manages five operational states-IDLE, READY1/2, ACTIVE, TRACEABLE, and AUTHENTICATED-with strict command gating per state.

Memory organization includes 60 pages × 4 bytes (240-byte total EEPROM), of which 144 bytes are user-programmable R/W space, 32-bit OTP, four lock bytes, and dedicated AES key storage (pages 48–55). Anti-tearing logic safeguards counter updates and lock-bit programming, while CMAC-based secure messaging (NIST SP 800-38B) ensures message integrity during authenticated sessions.

Key Specifications

Pinout & Package

MF0AESH2001DUDZ is supplied as a bare die on Film Frame Carrier (FFC), 120 µm thickness, requiring direct wire bonding to antenna substrates. No external power supply or digital interface pins are present - operation is fully contactless via LA/LB antenna terminals.

FAQ

What is the input capacitance specification of MF0AESH2001DUDZ and why does it matter?

The MF0AESH2001DUDZ has a nominal input capacitance of 50 pF, enabling direct integration with compact antennas in key fobs, wristbands, and thin tags without external tuning components. This value is confirmed in Table 2 of the official datasheet and distinguishes MF0AESH2001DUDZ from 17 pF variants like MF0AES2001DUDZ. The 50 pF design reduces antenna size requirements by ~3× compared to 17 pF versions, making MF0AESH2001DUDZ ideal for space-constrained applications where mechanical form factor is non-negotiable.

Does MF0AESH2001DUDZ support NFC Forum Tag Type 2 compliance?

Yes, MF0AESH2001DUDZ can be configured to comply with NFC Forum Tag 2 Type specifications per section 1.4 of the datasheet, enabling standard NDEF message formatting and interoperability with Android Beam and generic NFC reader apps. This capability is implemented in firmware and requires proper memory layout initialization during personalization - no hardware modification is needed. MF0AESH2001DUDZ retains full MIFARE protocol functionality while adding this layer of cross-platform compatibility.

How does the Random ID (RID) feature work on MF0AESH2001DUDZ?

The MF0AESH2001DUDZ supports optional Random ID generation per ISO/IEC 14443-3, replacing the fixed 7-byte UID with a dynamic 4-byte value during field operations. Activation requires AES authentication using UIDRetrKey to enter TRACEABLE state, after which RID is served instead of UID in REQA/WUPA responses. Real UID remains accessible only in authenticated sessions - this protects user privacy in surveillance-heavy environments like mass transit or stadiums while preserving backend traceability via cryptographic binding.

What memory protection mechanisms are available on MF0AESH2001DUDZ?

MF0AESH2001DUDZ provides three-tiered memory protection: (1) Page-level read/write locks programmable in-field for first 16 pages, (2) Block-level (2-page) locks for remaining memory, and (3) AES-128 authentication gates controlling access to protected pages and UID retrieval. Additionally, OTP bits and ECC-based originality signature prevent unauthorized reprogramming and ensure silicon authenticity. All lock states persist through power cycles and are enforced by hardware - no software bypass is possible.

Is MF0AESH2001DUDZ certified to Common Criteria standards?

Yes, MF0AESH2001DUDZ holds Common Criteria EAL3+ certification under AVA_VAN.2 (basic attack potential), as stated in section 1.5 of the datasheet. This certification validates resistance against logical attacks including side-channel analysis, fault injection, and unauthorized memory access attempts. Certification applies specifically to the MF0AES(H)20 product family and covers all security functions described - AES authentication, CMAC, RID, and originality verification - under defined threat models and evaluation scope.
