NXP Semiconductors MF1S7000XDA8/V1J

Overview

MF1S7000XDA8/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, 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 MF1S7000XDA8/V1J datasheet, MF1S7000XDA8/V1J pinout, MF1S7000XDA8/V1J application, or MF1S7000XDA8/V1J equivalent, this page delivers verified technical context, sector-based access control logic, UID configuration options, RF timing constraints, and real-world deployment considerations for secure contactless credential design.

Technical Context

The MF1S7000XDA8/V1J implements a dedicated ISO/IEC 14443A-compliant RF interface with integrated rectifier, voltage regulator, and clock regenerator - enabling passive operation without external power or components. Its CRYPTO1 stream cipher enforces sector-level security via two programmable keys per sector and configurable access bits stored in sector trailers.

Memory operations require prior anticollision selection and mutual three-pass authentication; supported commands include read, write, increment, decrement, restore, and transfer - with value blocks enforcing 2's complement format, triple-value storage, and address byte redundancy for electronic purse integrity.

Key Specifications

Pinout & Package

FAQ

What is the primary function of MF1S7000XDA8/V1J in a contactless system?

The MF1S7000XDA8/V1J serves as a secure contactless smart card IC compliant with ISO/IEC 14443 Type A. It provides 1 kB of EEPROM memory, 7-byte UID, mutual three-pass authentication, and value block operations - enabling trusted credential storage and cryptographic transactions in transit, access, and payment systems. Its RF interface harvests power and exchanges data at 13.56 MHz without external components.

Does MF1S7000XDA8/V1J support both 4-byte and 7-byte UID configurations?

No - MF1S7000XDA8/V1J is specifically configured with a 7-byte UID, as indicated by the "7000" prefix in its part number and confirmed in NXP's ordering information table. The 4-byte NUID variants are designated as MF1S5030XDA8/V1 or MF1S7030XDA8/V1. UID length is fixed at wafer-level programming and cannot be altered post-manufacture.

How does the MF1S7000XDA8/V1J handle memory access security?

The MF1S7000XDA8/V1J enforces memory access through sector-based authentication: each of its 16 sectors has a trailer block containing two secret keys (A and B) and programmable access bits. Before any read/write/increment operation, the host must authenticate using Key A or B. Access rights - including read, write, increment, or decrement - are determined by the sector trailer's access bits and apply independently per block.

What package type is used for MF1S7000XDA8/V1J, and how is it mounted?

MF1S7000XDA8/V1J is packaged in the MOA8 plastic leadless module carrier (SOT500-4), supplied on 35 mm wide tape. It is designed for embedding into PVC or PET smart card laminates - with LA and LB terminals bonded directly to the antenna coil. No PCB mounting or soldering is involved; integration relies on conductive adhesive or thermal lamination to the antenna structure.

Can MF1S7000XDA8/V1J be used in electronic purse applications?

Yes - MF1S7000XDA8/V1J supports electronic purse functionality via its value blocks. Each value block stores a signed 32-bit value in triple-redundant format (twice non-inverted, once inverted) with a 1-byte address field. Supported commands include increment, decrement, restore, and transfer - all executed under authenticated session with built-in backup management to prevent balance corruption during power loss.
