MIFARE Classic 4K - Mainstream contactless smart card IC
8. Functional description
8.1 Block description
The MF1S703x chip consists of a 4 kB EEPROM, RF interface and Digital Control Unit.
Energy and data are transferred via an antenna consisting of a coil with a small number of
turns which is directly connected to the MF1S703x. No further external components are
necessary. Refer to the document
Ref. 1
for details on antenna design.
RF interface:
–
Modulator/demodulator
–
Rectifier
–
Clock regenerator
–
Power-On Reset (POR)
–
Voltage regulator
Anti-collision: Multiple cards in the field may be selected and managed in sequence
Authentication: Preceding any memory operation the authentication procedure
ensures that access to a block is only possible via the two keys specified for each
block
Control and Arithmetic Logic Unit: Values are stored in a special redundant format and
can be incremented and decremented
EEPROM interface
Crypto unit: The CRYPTO1 stream cipher of the MF1S703x is used for authentication
and encryption of data exchange.
EEPROM: 4 kB is organized in 32 sectors with 4 blocks and 8 sectors with 16 blocks
each. A block contains 16 bytes. The last block of each sector is called “trailer”, which
contains two secret keys and programmable access conditions for each block in this
sector.
8.2 Communication principle
The commands are initiated by the reader and controlled by the Digital Control Unit of the
MF1S703x. The command response is depending on the state of the IC and for memory
operations also on the access conditions valid for the corresponding sector.
8.2.1
Request standard/all
After Power-On Reset (POR) the card answers to a request REQA or wakeup WUPA
command with the answer to request code (see
Section 9.4
, ATQA according to
ISO/IEC 14443A).
8.2.2
Anti-collision loop
In the anti-collision loop the identifier of a card is read. If there are several cards in the
operating field of the reader, they can be distinguished by their identifier and one can be
selected (select card) for further transactions. The unselected cards return to the idle state
and wait for a new request command.
Remark:
The identifier retrieved from the card is not defined to be unique. For further
information regarding handling of non-unique identifiers see
Ref. 7
