MIFARE Classic 1K - Mainstream contactless smart card IC
8. Functional description
8.1 Block description
The MF1S50yyX chip consists of a 1 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 MF1S50yyX. 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
Anticollision: 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 MF1S50yyX is used for
authentication and encryption of data exchange.
EEPROM: 1 kB is organized in 16 sectors of 4 blocks. One 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
MF1S50yyX. 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
Anticollision loop
In the anticollision 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. If the 7-byte UID is used for anticollision and
selection, two cascade levels need to be processes as defined in ISO/IEC 14443-3.
