NXP Semiconductors MF1S5000XDA4,118

Overview

MF1S5000XDA4,118 from NXP Semiconductors is a contactless smart card IC compliant with ISO/IEC 14443 Type A, implementing the MIFARE Classic 1K protocol. It features 1 kB EEPROM organized in 16 sectors, 13.56 MHz RF interface, mutual three-pass authentication, and 7-byte UID. It is deployed in public transport ticketing systems where sub-100 ms transaction time and sector-level key hierarchy are required.

For engineers reviewing the MF1S5000XDA4,118 datasheet, MF1S5000XDA4,118 pinout, MF1S5000XDA4,118 application, or MF1S5000XDA4,118 equivalent, this page delivers verified technical context including anticollision behavior, EEPROM access conditions, CRYPTO1 authentication flow, MOA4 module pin mapping, and real-world timing constraints for transit fare collection and access control integration.

Technical Context

The MF1S5000XDA4,118 integrates an RF interface compliant with ISO/IEC 14443A, a CRYPTO1 stream cipher for mutual three-pass authentication, and a digital control unit managing sector-based memory access. Its antenna interface requires no external components-only LA/LB coil connections-and operates without onboard power supply.

Memory is structured as 16 sectors × 4 blocks (16 bytes each), with sector trailers containing two keys (A mandatory, B optional) and programmable access bits. Authentication must precede all memory operations, and value blocks support increment/decrement/transfer with built-in backup management and triple-value storage for integrity.

FAQ

What is the primary function of the MF1S5000XDA4,118 in a contactless system?

The MF1S5000XDA4,118 serves as a secure, ISO/IEC 14443 Type A–compliant contactless smart card IC with 1 kB EEPROM, enabling applications like transit ticketing and access control. Its core function is to perform mutual three-pass authentication and execute sector-protected memory operations-including read, write, increment, and decrement-using the integrated CRYPTO1 engine. The MF1S5000XDA4,118 operates entirely from harvested RF energy and requires no external power source.

Does the MF1S5000XDA4,118 support both 4-byte and 7-byte UID configurations?

No-the MF1S5000XDA4,118 is specifically configured with a 7-byte UID, as indicated by the "00" in its part number suffix and confirmed in Table 2 of the datasheet. The 4-byte NUID variant is designated as MF1S5030XDA4,118. The MF1S5000XDA4,118 supports UIDF0–UIDF3 personalization modes for anticollision and selection but cannot be reconfigured to deliver a 4-byte identifier.

How does the MF1S5000XDA4,118 handle memory access security?

The MF1S5000XDA4,118 enforces memory access through sector-based authentication: each of its 16 sectors has a trailer block containing two keys (A mandatory, B optional) and access bits defining read/write/increment rights per block type. Before any operation, the host reader must authenticate using Key A or Key B. The MF1S5000XDA4,118 validates access conditions in real time and irreversibly blocks sectors upon format violation-ensuring persistent enforcement of security policies.

What antenna interface requirements apply to the MF1S5000XDA4,118?

The MF1S5000XDA4,118 uses a two-terminal LA/LB interface for direct connection to a tuned antenna coil, with no external capacitors or resistors required. Its input capacitance is 14.9–19.0 pF (typ. 16.9 pF), and optimal resonance is achieved when the coil's inductance and parasitic capacitance match the IC's internal tuning. Antenna geometry and reader field strength determine operating distance-up to 100 mm in ideal configurations. The MF1S5000XDA4,118 does not support external matching networks.

Can the MF1S5000XDA4,118 be used in electronic purse applications?

Yes-the MF1S5000XDA4,118 natively supports electronic purse functionality via value blocks, which implement hardware-verified increment, decrement, restore, and transfer commands with triple-value storage and address byte redundancy. These blocks enforce data integrity and prevent rollback or overflow attacks. The MF1S5000XDA4,118 retains values for 10 years and withstands 100,000 write cycles-meeting durability requirements for high-frequency balance updates in transit or campus payment systems.
