NXP Semiconductors MF0AES2000DA8J

Overview

MF0AES2000DA8J 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 at 13.56 MHz - deployed in public transport fare media and event access credentials.

For engineers reviewing the MF0AES2000DA8J datasheet, MF0AES2000DA8J pinout, MF0AES2000DA8J application, or MF0AES2000DA8J equivalent, this page details its RF interface architecture, AES-secured memory access model, UID/Random ID state transitions, and MOA8 module-level integration requirements for secure, high-throughput ticketing systems.

Technical Context

The MF0AES2000DA8J 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 three distinct operational states - ACTIVE, TRACEABLE, and AUTHENTICATED - governed by 3-pass AES authentication using either DataProtKey (pages 48–55) or UIDRetrKey (pages 52–55).

Memory protection includes per-page lock bits for the first 16 pages, block-wise locking above 512 bits, OTP configuration, and optional CMAC integrity checking per NIST SP 800-38B. The device supports both fixed 7-byte UID and switchable Random ID, with ECC-based originality signature verification enabled via READ_SIG command.

FAQ

What is the input capacitance of MF0AES2000DA8J and why does it matter?

The MF0AES2000DA8J has a fixed 17 pF input capacitance, optimized for standard antenna geometries used in MOA8 module-based cards and key fobs. This value determines the resonant frequency tuning with the external antenna coil - deviation beyond ±2 pF risks reduced read range or failed initialization. Matching this capacitance ensures reliable operation at 13.56 MHz across diverse reader field strengths.

How does MF0AES2000DA8J implement AES authentication and what keys are involved?

The MF0AES2000DA8J executes 3-pass mutual AES-128 authentication using two configurable keys: DataProtKey (stored at pages 48–55) for protecting user memory access, and UIDRetrKey (pages 52–55) for retrieving the 7-byte UID under Random ID mode. Authentication must succeed before entering AUTHENTICATED or TRACEABLE states - preventing unauthorized memory writes or UID exposure.

Can MF0AES2000DA8J be used in NFC Forum Tag Type 2 compliant systems?

Yes, MF0AES2000DA8J can be configured to comply with NFC Forum Tag Type 2 specification, supporting NDEF message formatting per NFC Forum specifications. This enables interoperability with Android and iOS devices for tap-to-launch actions, but requires proper NDEF formatting during personalization - the underlying AES security remains active and does not interfere with NDEF operation.

What memory protection mechanisms does MF0AES2000DA8J provide beyond AES authentication?

MF0AES2000DA8J provides layered memory protection: field-programmable per-page lock bits for the first 16 pages, block-wise read-only locking for higher memory regions, 32-bit OTP area for immutable configuration, and anti-tearing logic for counters and lock bits. These operate independently of AES state - meaning locked pages remain inaccessible even after successful authentication unless explicitly unlocked via authorized commands.

Is MF0AES2000DA8J certified to Common Criteria and what does that cover?

MF0AES2000DA8J holds Common Criteria EAL3+ certification (AVA_VAN.2), validating resistance against basic logical attacks including side-channel analysis and fault injection targeting the AES engine and memory controller. This certification applies specifically to the MF0AES(H)20 silicon revision and confirms secure execution of AES authentication, CMAC generation, and UID signature verification - but does not extend to system-level implementation flaws.
