NXP Semiconductors MF3D8201DUF/01V

Overview

MF3D8201DUF/01 from NXP Semiconductors is a contactless multi-application IC compliant with ISO/IEC 14443A, featuring 8 KB EEPROM, 17 pF input capacitance, Common Criteria EAL5+ security certification, and support for AES-128 and 3DES cryptographic engines. It serves as the secure core of smart city mobility cards, enabling concurrent public transport, e-payment, and access control on a single credential.

For engineers reviewing the MF3D8201DUF/01 datasheet, MF3D8201DUF/01 pinout, MF3D8201DUF/01 application, or MF3D8201DUF/01 equivalent, key selection considerations include its 70 mm operational range at 848 kbit/s, Transaction MAC file support for backend auditability, MIsmartApp delegated management capability, Proximity Check against relay attacks, and backward compatibility with MIFARE DESFire EV1 and D40 infrastructure.

Technical Context

The MF3D8201DUF/01 implements a dual-layer security architecture: hardware-accelerated AES-128 and 3DES crypto engines coexist with mutual three-pass authentication and CMAC-based data integrity verification. Its flexible file system supports up to 32 files per application across six types-including Transaction MAC-each sized dynamically at creation.

It operates at 13.56 MHz RF carrier frequency with configurable ATS supporting up to 128-byte frames (256 bytes for larger memory variants), and integrates Proximity Check and Originality Check sensors to detect physical relay attacks and verify genuine NXP silicon-both enabled at firmware level without external components.

Key Specifications

Pinout & Package

MF3D8201DUF/01 is supplied in FFC (Film Frame Carrier) package format - an 8-inch wafer-level die with 75 μm thickness, intended for embedding into smart card laminates or inlays. No discrete pins or terminals are present; electrical interface is exclusively contactless via integrated coil coupling.

FAQ

What security certifications does the MF3D8201DUF/01 hold?

The MF3D8201DUF/01 holds Common Criteria EAL5+ certification for both hardware and software, validating its resistance to physical, side-channel, and fault-injection attacks. This certification level matches that required for electronic passports and banking cards. The MF3D8201DUF/01 also supports ISO/IEC 7816-4 APDU commands and implements mutual three-pass authentication using AES-128 or 3DES, with all cryptographic operations executed in hardened silicon.

How does the MF3D8201DUF/01 differ from earlier MIFARE DESFire generations?

The MF3D8201DUF/01 introduces MIsmartApp delegated application management, Transaction MAC files, Proximity Check, Originality Check, and Virtual Card Architecture - features absent in MF3D8201DUF/01's predecessors. Unlike MIFARE DESFire EV1, it removes application count limits (previously capped at 28) and expands communication buffer size to 128 bytes. It maintains full backward compatibility with EV1 and D40 systems through configurable default operation mode.

What is the purpose of the Transaction MAC file type in MF3D8201DUF/01?

Within the MF3D8201DUF/01, the Transaction MAC file type generates a cryptographically signed log of each transaction - including timestamps, amounts, and service identifiers - using a secret key stored securely on the IC. This provides auditable, tamper-evident proof of completed actions for backend reconciliation without transmitting sensitive data over RF, directly supporting closed-loop e-payment and fare capping compliance.

Can MF3D8201DUF/01 operate in Random ID mode, and what are its implications?

Yes, the MF3D8201DUF/01 supports Random ID mode, generating a new 3-byte identifier after each RF reset to prevent tracking across readers. This enhances user privacy in public-facing deployments like event ticketing or municipal services. However, Random ID disables multi-application chaining and requires reader-side support for single-loop anti-collision - unlike fixed UID mode, which enables deterministic application selection in complex multi-service workflows.

What package form is MF3D8201DUF/01 delivered in, and how is it integrated?

The MF3D8201DUF/01 is supplied in FFC (Film Frame Carrier) format - an 8-inch wafer sawn into individual 75 μm-thick dies mounted on adhesive film. It is designed for direct embedding into smart card laminates or RFID inlays using standard hot-stamping or lamination processes. No wire bonding or soldering is required; RF coupling occurs via integrated antenna traces in the final card substrate.
