10 / 132 page  NXP Semiconductors MF2DL(H)x0 MIFARE DESFire Light contactless application IC MF2DL_H_x0 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2019. All rights reserved. Product data sheet Rev. 3.3 — 5 April 2019 COMPANY PUBLIC 430733 10 / 132 8.2.2 Default Application Name and ID MF2DL(H)x0 is pre-configured with one application. The default DF name and File ID are as follows: • DF Name: A00000039656434103F015400000000Bh • File Identifier: DF01h DF Name and File ID can be changed using SetConfiguration command. 8.2.3 Files MF2DL(H)x0 stores user data into EF (files) of specific types. All files but the TransactionMAC File are statically created and cannot be deleted. However, file IDs and file settings can be changed using the SetConfiguration command. The ChangeFileSettings command can be used to change the access rights configuration. Any file number between 00h and 1Fh and any allowed File ID can be set. Note, that duplication of a file number or a file ID is not allowed. Only the TMAC file can be deleted and re-created in order to generate a new TMAC configuration or disable the TMAC feature. File access rights can be restricted with the keys of the application. Table 5. File management EF (File) Type File type coding Default file no. Default file ID File size Example uses 00h [1] EF00h 256 bytes Storage of raw data e.g. information 04h EF04h 256 bytes Storage of raw data e.g. information StandardData file 00h 1Fh[1] EF1Fh 32 bytes FCI template or data Value file 02h 03h - - Storage of value, points, customized counter CyclicRecord file 04h 01h EF01h 4 records á 16 bytes Storage of log, activities TransactionMAC file 05h 0Fh - - Transaction counter, Transaction MAC, Reader ID, Limit of application selection. [1] Note that this File no. needs to be explicitly selected via ISOSelectFile for ISOReadBinary or ISOUpdateBinary as it is reserved in the scope of implicit selection. The File no. can be changed in order to leverage implicit selection. 8.2.3.1 StandardData file A StandardData file stores the data as raw data bytes. Data is accessed by chunk of byte at a certain offset in the StandardData file and with a certain byte length. The content of file no. 1Fh is returned as FCI at Section 11.10.1 of the DF, if the read access of this file is set to "free". Note that also one of the larger files can be used to hold FCI information in case it is renamed to 1Fh. A StandardData file can be read with the ReadData and ISOReadBinary commands. The data can be written with the WriteData and ISOUpdateBinary commands. ISOReadBinary and ISOUpdateBinary are standard ISO/IEC 7816-4 interindustry commands, see [4]. |
