NXP Semiconductors MF1S5000XDA8/V1J

Overview

MF1S5000XDA8/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, 7-byte UID, mutual three-pass authentication, and 13.56 MHz RF interface - deployed in public transport ticketing systems requiring sub-100 ms transaction time.

For engineers reviewing the MF1S5000XDA8/V1 datasheet, MF1S5000XDA8/V1 pinout, MF1S5000XDA8/V1 application, or MF1S5000XDA8/V1 equivalent, key selection considerations include UID length (7-byte), MOA8 module packaging (SOT500-4), sector-based access control, CRYPTO1 encryption, and compatibility with MIFARE Classic EV1 infrastructure.

Technical Context

The MF1S5000XDA8/V1 implements a dedicated RF interface per ISO/IEC 14443A, including modulator/demodulator, rectifier, clock regenerator, and voltage regulator - enabling passive operation powered solely by reader field. Its digital control unit executes anticollision, authentication, and memory operations without external components.

Memory is structured as 16 sectors × 4 blocks (16 bytes/block), with sector trailers storing dual keys (A/B) and programmable access bits. The CRYPTO1 stream cipher enforces sector-level security during three-pass authentication, and value blocks support atomic increment/decrement/transfer for electronic purse use cases.

FAQ

What is the primary function of the MF1S5000XDA8/V1 in a contactless system?

The MF1S5000XDA8/V1 serves as a secure, ISO/IEC 14443 Type A-compliant contactless smart card IC. It stores and protects credential data (e.g., transit tickets, access rights) using 1 kB of EEPROM, enforces access control via sector-based keys and CRYPTO1 authentication, and communicates wirelessly via its LA/LB antenna terminals - all without external power.

Does the MF1S5000XDA8/V1 support both read and write operations, and under what conditions?

Yes, the MF1S5000XDA8/V1 supports read, write, increment, decrement, restore, and transfer operations - but only after successful three-pass authentication with either Key A or Key B for the target sector. Access permissions are enforced by sector trailer access bits, and unauthorized attempts result in command rejection or sector lockout.

How does the 7-byte UID in MF1S5000XDA8/V1 differ from the 4-byte NUID option, and why does it matter?

The MF1S5000XDA8/V1 features a factory-programmed 7-byte UID, ensuring global uniqueness required for secure, auditable systems like public transport. In contrast, 4-byte NUID variants (e.g., MF1S5030XDA8/V1) lack guaranteed uniqueness - making them unsuitable for open infrastructure where ID collisions could compromise fare integrity or access logs.

Can the MF1S5000XDA8/V1 be used in electronic purse applications, and what hardware features enable this?

Yes, the MF1S5000XDA8/V1 supports electronic purse functionality through its value blocks - specially formatted 16-byte memory regions that implement atomic increment/decrement/transfer commands with built-in error detection, backup management, and 2's complement value storage. These blocks require authentication and operate under strict access bit control per sector.

What package type and mounting configuration does the MF1S5000XDA8/V1 use, and how is it integrated?

The MF1S5000XDA8/V1 is supplied in MOA8 plastic leadless module carrier package (SOT500-4), delivered on 35 mm wide tape. It integrates directly onto antenna substrates via LA and LB terminals - no soldering or PCB traces are needed. The module is designed for embedding into PVC or PET smart cards, with antenna coil inductance tuned to resonate at 13.56 MHz.
