Overview
MF1S5031XDUD/V1 from NXP Semiconductors is a contactless smart card IC compliant with ISO/IEC 14443 Type A, featuring 1 kB EEPROM organized in 16 sectors, 4-byte non-unique ID (NUID), 13.56 MHz operating frequency, and Crypto1-based three-pass authentication. It enables fast ticketing transactions (<100 ms) in public transport fare collection systems.
For engineers reviewing the MF1S5031XDUD/V1 datasheet, MF1S5031XDUD/V1 pinout, MF1S5031XDUD/V1 application, or MF1S5031XDUD/V1 equivalent, key selection considerations include NUID vs UID identity model, sector-level key hierarchy support, EEPROM write endurance (200,000 cycles), and compatibility with MIFARE Classic EV1 reader ecosystems.
Technical Context
The MF1S5031XDUD/V1 implements a dedicated RF interface per ISO/IEC 14443A with integrated rectifier, voltage regulator, clock regenerator, and Power-On Reset - requiring no external components beyond an antenna coil. Its digital control unit handles anticollision, authentication, and memory operations without host processor intervention.
It uses the CRYPTO1 stream cipher for mutual three-pass authentication and supports value-block arithmetic (increment/decrement/transfer) with built-in backup management. Memory access is enforced per sector trailer-defined access bits, enabling multi-application key hierarchies using Key A and optional Key B.

FAQ
What is the identifier type used in MF1S5031XDUD/V1?
The MF1S5031XDUD/V1 uses a 4-byte non-unique ID (NUID), confirmed by its ATQA response value of 0004h per ISO/IEC 14443. Unlike the 7-byte UID variant, this version does not guarantee global uniqueness and is intended for closed-loop systems where identifier collision is managed at the application layer. The NUID is factory-programmed and cannot be altered.
Does MF1S5031XDUD/V1 support the same command set as other MIFARE Classic 1K variants?
Yes, MF1S5031XDUD/V1 supports the full MIFARE Classic EV1 command set including REQA/WUPA, anticollision, SELECT, AUTHENTICATE (60h/61h), READ (30h), WRITE (A0h), INCREMENT (C1h), DECREMENT (C0h), TRANSFER (B0h), and HALT (50h00h). All commands operate identically to MF1S5001XDUD/V1 except those dependent on UID length - such as cascade level handling during anticollision.
How is power delivered to MF1S5031XDUD/V1 during operation?
MF1S5031XDUD/V1 is powered entirely through electromagnetic induction from a 13.56 MHz RF field generated by the reader. Its internal voltage regulator and rectifier convert energy received across the LA–LB antenna terminals into stable DC supply for the EEPROM, logic unit, and crypto engine - requiring zero external power sources or capacitors.
Can MF1S5031XDUD/V1 be used in value-block applications like electronic purses?
Yes, MF1S5031XDUD/V1 fully supports value-block functionality: increment, decrement, restore, and transfer operations are implemented in hardware with triple-value storage and address backup for error resilience. These operations require prior authentication and are restricted to blocks configured as value blocks via sector trailer access bits - enabling secure electronic purse implementations.
What package form is MF1S5031XDUD/V1 supplied in?
MF1S5031XDUD/V1 is supplied as a bumped die on an 8-inch silicon wafer (120 μm thickness), mounted on a film frame carrier (FFC Bump). It is not packaged in a leaded or module format - instead, it is intended for direct wire bonding or flip-chip attachment to custom antenna substrates in smart card or tag manufacturing.
