It enables secure public transport ticketing, micro-payment, and access management in single-card deployments.

For engineers reviewing the MF3D9200DA4/02J datasheet, MF3D9200DA4/02J pinout, MF3D9200DA4/02J application, or MF3D9200DA4/02J equivalent, key selection considerations include its 16 KB NV memory capacity, 17 pF input capacitance, SOT500-2 MOB4 package, EV2-specific Transaction MAC and MIsmartApp features, and backward compatibility with MIFARE DESFire EV1 and D40 systems.

Technical Context

The MF3D9200DA4/02J implements a dedicated ISO/IEC 14443-4 RF interface supporting data rates up to 848 kbit/s and configurable frame size (up to 128 bytes for 16 KB variant). Its on-chip CPU executes a certified secure operating system with mutual three-pass authentication and hardware-accelerated AES-128 and 3DES cryptographic engines.

It supports six file types-including Transaction MAC files-and enforces application-level isolation via per-application key sets (up to 14 keys), delegated application management (MIsmartApp), and Virtual Card Architecture for privacy-preserving card selection. The device includes Proximity Check and Originality Check hardware sensors to counter relay attacks and verify genuine NXP silicon.

Key Specifications

Pinout & Package

MF3D9200DA4/02J is housed in a MOB4 plastic leadless module carrier package (SOT500-2), designed for embedding into smart cards, wearables, and secure tokens. It has no external pins - RF coupling occurs via integrated coil interface; electrical connection is made through two conductive pads (V_DD and GND) for test/probe access during personalization.

FAQ

What security certifications does the MF3D9200DA4/02J hold?

The MF3D9200DA4/02J holds Common Criteria EAL5+ certification for both hardware and software - the highest publicly available assurance level for smart card ICs, equivalent to that required for banking cards and electronic passports. This certification validates its resistance to side-channel attacks, fault injection, and logical exploits. The MF3D9200DA4/02J also implements hardware-based mutual three-pass authentication, Proximity Check, and Originality Check to prevent relay attacks and counterfeit devices.

Is the MF3D9200DA4/02J compatible with existing MIFARE DESFire EV1 infrastructure?

Yes, the MF3D9200DA4/02J operates in default delivery configuration as a MIFARE DESFire EV1 device, ensuring full backward compatibility with legacy readers and middleware. All EV1 commands and secure messaging modes (including 2TDEA and AES-based AuthenticateISO) are supported. New EV2 features - such as Transaction MAC, MIsmartApp, and Virtual Card Architecture - require explicit activation via dedicated commands and do not interfere with existing EV1 deployments.

What is the difference between MF3D9200DA4/02J and MF3DH9200DA4/02J?

The MF3D9200DA4/02J uses 17 pF input capacitance and is optimized for standard antenna geometries in ISO/IEC 7816-1/2 card formats. The MF3DH9200DA4/02J uses 70 pF input capacitance and is intended for compact or flexible antenna designs - such as wearables or thin smart labels - where higher capacitance improves coupling efficiency. Both share identical 16 KB EEPROM, SOT500-2 MOB4 packaging, and feature set; the capacitance difference dictates antenna design requirements, not functional capability.

Does the MF3D9200DA4/02J support ISO/IEC 7816-4 APDU commands?

Yes, the MF3D9200DA4/02J fully supports ISO/IEC 7816-4 APDU structure and command set, including SELECT FILE (INS A4), READ BINARY (INS B0), UPDATE BINARY (INS D6), READ RECORDS (INS B2), APPEND RECORD (INS E2), GET CHALLENGE (INS 84), INTERNAL AUTHENTICATE (INS 88), and EXTERNAL AUTHENTICATE (INS 82). It also supports ISO/IEC 7816-4 file structure navigation by DF name or File ID - enabling integration with existing PKI and EMV-compliant backends without protocol translation.

How many applications and files can the MF3D9200DA4/02J support?

The MF3D9200DA4/02J supports an unlimited number of applications - constrained only by available 16 KB EEPROM space - with up to 32 files per application. Six file types are supported: Standard Data, Backup Data, Value, Linear Record, Cyclic Record, and Transaction MAC. File sizes are user-defined at creation time (except Transaction MAC files, which are fixed), and each application maintains independent key sets (up to 14 keys) and access rights - enabling true multi-tenant, multi-service deployment on a single IC.
