Product details
Overview
MF1S7000XDA4/V1J 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 operates at 13.56 MHz, supports 106 kbit/s data transfer, and enables sub-100 ms ticketing transactions - deployed in public transport fare collection systems.
For engineers reviewing the MF1S7000XDA4/V1J datasheet, MF1S7000XDA4/V1J pinout, MF1S7000XDA4/V1J application, or MF1S7000XDA4/V1J equivalent, this page delivers verified technical identity, antenna interface details, memory security architecture, sector-level access control, and real-world deployment constraints for MIFARE Classic EV1 1K system integration.
Technical Context
The MF1S7000XDA4/V1J implements a fully integrated RF interface per ISO/IEC 14443A, including rectifier, voltage regulator, clock regenerator, and Power-On Reset - requiring no external components beyond an antenna coil. Its digital control unit manages anticollision, three-pass authentication, and encrypted memory operations via the CRYPTO1 stream cipher.
Memory is partitioned into 16 sectors (each with 4 × 16-byte blocks), where sector trailers store dual keys (A/B) and programmable access bits governing read/write/increment/decrement permissions per block. Value blocks support electronic purse functions with built-in backup management and triple-stored signed 4-byte values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Frequency | 13.56 MHz - Enables interoperability with global ISO/IEC 14443A readers and infrastructure. |
| Memory Capacity | 1 kB EEPROM - Organized as 16 sectors × 4 blocks × 16 bytes; last block per sector stores keys and access conditions. |

IC Role / Device Role / Timing Role: Secure memory partitioning platform hosting independent applications (e.g., value blocks for meal credits, data blocks for biometric templates). Use Value: Value block format with built-in error correction ensures accurate balance updates even under marginal RF coupling conditions common in campus card readers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar contactless smart card IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MF1S5000XDA4/V1 | Same MOA4 package (SOT500-2), identical 1 kB memory and 7-byte UID - differs only in part number suffix; functionally identical to MF1S7000XDA4/V1J per NXP ordering documentation. | No functional difference; both target mainstream MIFARE Classic EV1 1K deployments requiring 7-byte UID and MOA4 form factor. | Select MF1S5000XDA4/V1 when sourcing standard production-grade MOA4 modules without J-suffix traceability marking. |
| MF1S7030XDA4/V1J | Same MOA4 package and pinout, but uses 4-byte non-unique ID (NUID) instead of 7-byte UID - impacts anticollision reliability and uniqueness guarantees in dense-reader environments. | Suitable for cost-sensitive, low-security applications where UID collision tolerance is acceptable (e.g., internal event badges), not recommended for fare collection or access control. | Choose MF1S7030XDA4/V1J only if NUID suffices for your system's identifier uniqueness requirements and anticollision robustness budget. |
Compared with MF1S7000XDA4/V1J, MF1S5000XDA4/V1 offers identical functionality and packaging for standard procurement, while MF1S7030XDA4/V1J trades UID uniqueness for lower cost - making the former a drop-in alternative and the latter a constrained-use option requiring system-level validation of NUID handling.

FAQ
What is the exact memory organization of the MF1S7000XDA4/V1J?
The MF1S7000XDA4/V1J contains 1024 bytes of EEPROM organized into 16 sectors, each comprising 4 blocks of 16 bytes. Sector 0 includes a manufacturer block (block 0), two data blocks, and a sector trailer (block 3); all other sectors contain three data blocks and a trailer. Each trailer holds keys A/B and access condition bits governing block-level permissions.
Does the MF1S7000XDA4/V1J support both Key A and Key B authentication per sector?
Yes, the MF1S7000XDA4/V1J supports dual-key authentication per sector: Key A is mandatory and always present; Key B is optional and may be disabled or configured as readable depending on access bit settings in the sector trailer. Authentication with either key enables memory operations subject to the sector's programmed access conditions.
What antenna design considerations apply to the MF1S7000XDA4/V1J?
The MF1S7000XDA4/V1J requires an external antenna coil connected between LA and LB pins. Antenna inductance must resonate with the IC's internal capacitance (~16.9 pF) at 13.56 MHz; typical designs use 1–5 µH inductance with quality factor >20. NXP Application Note AN11010 provides validated reference layouts and impedance matching guidelines for optimal 100 mm operating distance.
Is the MF1S7000XDA4/V1J compatible with ISO/IEC 14443-4 protocols?
No, the MF1S7000XDA4/V1J implements only ISO/IEC 14443 Type A at the physical and MAC layers (Parts 1–3), and does not support ISO/IEC 14443-4's higher-layer protocol (TPDU exchange). It is strictly a Type A, Level 2 (PICC) device - interoperable with standard MIFARE readers but not with DESFire or other ISO/IEC 14443-4-compliant systems.
How is data integrity ensured during wireless communication with the MF1S7000XDA4/V1J?
The MF1S7000XDA4/V1J enforces data integrity through 16-bit CRC per block, odd parity per byte, bit counting, Manchester-style bit coding (to distinguish 0/1/no-signal), and real-time channel monitoring. These mechanisms collectively detect and reject corrupted frames before they reach the crypto or memory subsystems - ensuring authenticated operations act only on valid data.
