Product data sheet Rev. 3.3 — 5 April 2019 COMPANY PUBLIC 430733 9 / 132 8.1.2 Setting of higher communication speed After receiving an ATS, a PPS request can be sent to the MF2DL(H)x0 to set up a higher communication speed up to 848 kbit/s according to ISO/IEC 14443-4 [3]. 8.1.3 Half-duplex block transmission protocol MF2DL(H)x0 uses half-duplex block transmission protocol as specified in ISO/IEC 14443-4. It is fully compliant to block format, frame waiting time, frame waiting time extension, protocol operation, and all rules or handling as in [3]. 8.2 User memory The file system in the user memory is according to ISO/IEC 7816-4 and shown in Figure 4. In the DF (application), there are 6 EFs (files) and 5 keys. aaa-032188 PICC/MF Level ISO MF Name = D2760000850100h ISO File ID = 3F00h Application/DF Level Default File No. 00h Standard Data File 256 bytes Def.

MIFARE DESFire Light application 8.2.1 Application and file selection The MF (PICC Level), the DF (application) and the EFs (files) can be selected using the ISOSelectFile command specified in ISO/IEC 7816-4 [4] and described in Section 11.10.1. The PICC level refers to the card itself and has the ISO DF Name D2760000850100h and the File ID 3F00h. The only functionality available on PICC level is an LRP mode authentication using an OriginalityKey and the retrieval of the originality signature using the Read_Sig command, see Section 11.11.1. |
