NXP Semiconductors MF1S5000XDA4/V1J

Overview

MF1S5000XDA4/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, and CRYPTO1-based mutual three-pass authentication. It delivers typical transaction times under 100 ms and supports public transport ticketing, access management, and electronic toll collection.

For engineers reviewing the MF1S5000XDA4/V1 datasheet, MF1S5000XDA4/V1 pinout, MF1S5000XDA4/V1 application, or MF1S5000XDA4/V1 equivalent, key selection considerations include UID length (7-byte), MOA4 module packaging (SOT500-2), sector-based key hierarchy, 13.56 MHz RF interface, and value-block support for electronic purse functions.

Technical Context

The MF1S5000XDA4/V1 implements a dedicated RF interface per ISO/IEC 14443A, integrating rectifier, clock regenerator, voltage regulator, and Power-On Reset - enabling fully passive operation powered solely by the reader's 13.56 MHz carrier field. Its digital control unit executes anticollision, authentication, and memory operations without external components.

Authentication relies on the proprietary CRYPTO1 stream cipher, enforcing sector-level access control via two keys (A/B) and programmable access bits stored in each sector trailer. Memory operations - including read, write, increment, decrement, restore, and transfer - are gated by successful authentication and validated against block-type-specific command permissions.

Key Specifications

FAQ

What is the primary function of the MF1S5000XDA4/V1 in a contactless system?

The MF1S5000XDA4/V1 serves as a secure, ISO/IEC 14443 Type A-compliant contactless smart card IC. Its core function is to store and protect application data (e.g., transit balances, access credentials) using sector-based encryption, authenticate securely with readers via CRYPTO1, and execute fast, reliable transactions - all powered wirelessly by the reader's 13.56 MHz field. The MF1S5000XDA4/V1 requires no battery or wired power.

Does the MF1S5000XDA4/V1 support both 4-byte and 7-byte identifiers?

No - the MF1S5000XDA4/V1 is specifically configured with a factory-programmed 7-byte UID, as confirmed by its ordering code suffix "00" (indicating UID version) and MOA4 packaging. The 4-byte NUID variant is designated as MF1S5030XDA4/V1. The MF1S5000XDA4/V1 supports Random ID mode and NXP Originality Check, features not available on NUID versions.

What package type and pin configuration does the MF1S5000XDA4/V1 use?

The MF1S5000XDA4/V1 is supplied in the MOA4 plastic leadless module carrier package (SOT500-2), as specified in NXP's ordering information table. It has exactly two terminals: LA and LB, which connect directly to the antenna coil. There are no digital I/O pins, power supply pins, or ground connections - the MF1S5000XDA4/V1 operates entirely passively via magnetic coupling.

Can the MF1S5000XDA4/V1 be used in electronic purse applications?

Yes - the MF1S5000XDA4/V1 natively supports electronic purse functionality through its value block architecture. Each value block stores a signed 4-byte value three times (twice non-inverted, once inverted) with built-in backup management, enabling secure, atomic increment, decrement, restore, and transfer operations - all protected by sector-level CRYPTO1 authentication. This makes the MF1S5000XDA4/V1 suitable for prepaid transit or cafeteria cards.

How does the anticollision feature of the MF1S5000XDA4/V1 work in practice?

The MF1S5000XDA4/V1 implements ISO/IEC 14443-3 compliant cascade-level anticollision, allowing multiple cards to be present in a reader's field simultaneously. It responds to REQA/WUPA commands with ATQA, then participates in a deterministic selection loop using its 7-byte UID across two cascade levels. The MF1S5000XDA4/V1 ensures only one card is selected per transaction, preventing data corruption - critical for high-density environments like crowded transit gates.
