[1] If key B may be read in the corresponding Sector Trailer it cannot serve for authentication (see grey marked lines in Table
7). As a consequences, if the reader authenticates any block of a sector which uses such access conditions for the Sector
Trailer and using key B, the card will refuse any subsequent memory access after authentication.
9 Command overview
Note: In this document the term „MIFARE Classic card“ refers to a MIFARE Classic IC-
based contactless card.
The MIFARE Classic card activation follows the ISO/IEC 14443 Type A. After the
MIFARE Classic card has been selected, it can either be deactivated using the ISO/IEC
14443 Halt command, or the MIFARE Classic commands can be performed. For more
details about the card activation refer to Ref. 4.
9.1 MIFARE Classic command overview
All MIFARE Classic commands typically use the MIFARE Classic using Crypto1 and
require an authentication.
All available commands for the MIFARE Classic EV1 with 1K memory are shown in Table
9.

All commands use the coding and framing as described in Ref. 3 and Ref. 4 if not
otherwise specified.
9.2 Timings
The timing shown in this document are not to scale and values are rounded to 1 μs.
All given times refer to the data frames including start of communication and end of
communication. A PCD data frame contains the start of communication (1 "start bit")
and the end of communication (one logic 0 + 1 bit length of unmodulated carrier). A
PICC data frame contains the start of communication (1 "start bit") and the end of
communication (1 bit length of no subcarrier).
The minimum command response time is specified according to Ref. 4 as an integer n
which specifies the PCD to PICC frame delay time. The frame delay time from PICC to
PCD is at least 87 μs. The maximum command response time is specified as a time-out
value. Depending on the command, the T
ACK
value specified for command responses
defines the PCD to PICC frame delay time. It does it for either the 4-bit ACK value
specified in Section 9.3 or for a data frame.
All command timings are according to ISO/IEC 14443-3 frame specification as shown for
the Frame Delay Time in Figure 11. For more details refer to Ref. 3 and Ref. 4.

Remark: Due to the coding of commands, the measured timings usually excludes (a part

measured times.

9.3 MIFARE Classic ACK and NAK
The MIFARE Classic uses a 4 bit ACK / NAK as shown in Table 10.

9.4 ATQA and SAK responses
For details on the type identification procedure please refer to Ref. 2.
The MF1S50yyX/V1 answers to a REQA or WUPA command with the ATQA value
shown in Table 11 and to a Select CL1 command (CL2 for the 7-byte UID variant) with
the SAK value shown in Table 12.

Remark: The ATQA coding in bits 7 and 8 indicate the UID size according to ISO/IEC
14443 independent from the settings of the UID usage.
Remark: The bit numbering in the ISO/IEC 14443 starts with LSBit = bit 1, but not LSBit
= bit 0. So one byte counts bit 1 to 8 instead of bit 0 to 7.
