Mainstream contactless smart card IC

10. Command overview

The MIFARE card activation follows the ISO/IEC 14443-3 type A. After the MIFARE card

has been selected, it can either be deactivated using the ISO/IEC 14443 Halt command,

or the MIFARE commands can be performed. For more details about the card activation

refer to Ref. 4

10.1 MIFARE command overview

All MIFARE Classic commands use the MIFARE Crypto1 and require an authentication.

All available commands for the MIFARE Classic are shown in Table 8

All the commands use the coding and framing as described in Ref. 3 and Ref. 4 (e.g.

parity) if not otherwise specified.

10.2 Timings

In this document the timing shown is not to scale and rounded to 1 μs.

All the given times refer to the data frames including start of communication and end of

communication, but do not include the encoding (like the Miller pulses).

Consequently a data frame sent by the PCD contains the start of communication (1 “start

bit”) and the end of communication (one logic 0 + 1 bit length of unmodulated carrier).

A data frame sent by the PICC contains the start of communication (1 “start bit”) and the

end of communication (1 bit length of no subcarrier).
