NXP Semiconductors MF0AESH2001DUFZ

Overview

MF0AESH2001DUFZ from NXP Semiconductors is a contactless smart IC for limited-use ticketing and RFID key cards, featuring AES-128 mutual authentication, 144-byte user memory organized in 36 pages of 4 bytes each, 50 pF input capacitance for compact form factors (e.g., key fobs, wristbands), and full ISO/IEC 14443-3A compliance. It enables secure public transport tickets, event passes, and hospitality guest cards with anti-tearing counter protection and optional Random ID for GDPR-aligned privacy.

For engineers reviewing the MF0AESH2001DUFZ datasheet, MF0AESH2001DUFZ pinout, MF0AESH2001DUFZ application, or MF0AESH2001DUFZ equivalent, this page delivers verified technical context, memory layout details, RF interface behavior, security state transitions, and real-world deployment constraints - all grounded in NXP's Rev. 3.3 product data sheet dated 6 February 2026.

Technical Context

The MF0AESH2001DUFZ implements a dedicated AES coprocessor supporting 3-pass mutual authentication using two configurable 128-bit keys: [DataProtKey] for protected memory access and [UIDRetrKey] for UID retrieval. Its digital control unit manages five operational states - IDLE, READY1/READY2, ACTIVE, TRACEABLE, and AUTHENTICATED - with strict command gating per state, including VCSL prohibition in TRACEABLE mode when standard UID is active.

RF communication follows ISO/IEC 14443-3A at 13.56 MHz with 106 kbit/s data rate, 16-bit CRC, parity, and bit coding for integrity. Memory includes three independent 24-bit one-way counters (one optionally AES-authenticated), 32-bit OTP area, and field-programmable lock bits per page (first 16 pages) or per 2-page block (remaining memory), all backed by anti-tearing logic.

FAQ

What is the input capacitance of MF0AESH2001DUFZ and why does it matter?

The MF0AESH2001DUFZ has a 50 pF input capacitance, optimized for compact antenna designs in key fobs, wristbands, and thin tags. This eliminates the need for external capacitors or antenna tuning adjustments, reducing bill-of-materials cost and accelerating time-to-market for wearables and small-format credentials. Unlike 17 pF variants, the 50 pF version achieves reliable 10 cm read range even with miniaturized coils.

Does MF0AESH2001DUFZ support both fixed UID and Random ID?

Yes, MF0AESH2001DUFZ supports both 7-byte fixed UID and optional Random ID (RID). RID activation requires AES authentication using [UIDRetrKey] in TRACEABLE or AUTHENTICATED state. When RID is enabled, the IC returns zeros for UID reads in ACTIVE state - enforcing privacy-by-design for GDPR-compliant deployments such as corporate access or healthcare visitor badges.

How many authentication keys does MF0AESH2001DUFZ support and what are their roles?

MF0AESH2001DUFZ supports two distinct 128-bit AES keys: [DataProtKey] for accessing authentication-protected memory pages and [UIDRetrKey] for retrieving the fixed UID or originality signature. Each key operates independently within separate state transitions - ensuring that UID exposure does not compromise protected data access, and vice versa - a core requirement for layered security architectures.

What memory protection mechanisms are implemented in MF0AESH2001DUFZ?

MF0AESH2001DUFZ provides per-page lock bits for the first 16 pages (64 bytes), per-2-page lock blocks for remaining memory, 32-bit OTP programming, and AES-based authentication gates for memory access. Lock bits are field-programmable and persistent; OTP bits are one-time writable. All protections include anti-tearing logic to prevent corruption during interrupted writes - essential for reliable counter updates in transit fare systems.

Is MF0AESH2001DUFZ certified to any security standards?

Yes, MF0AESH2001DUFZ holds Common Criteria EAL3+ certification under AVA_VAN.2, validating resistance against basic logical and physical attacks. This certification covers the IC's AES coprocessor, memory protection logic, and anti-tearing mechanisms. Note that EAL3+ targets basic attack potential - for higher-threat environments, NXP recommends MIFARE DESFire EV3 or similar EAL5+-certified products.
