1. General description
NXP Semiconductors has developed the MIFARE Classic MF1S70yyX to be used in a
contactless smart card according to ISO/IEC 14443 Type A.
The MIFARE Classic 4K MF1S70yyX IC is used in applications like public transport
ticketing and can also be used for various other applications.
1.1 Anticollision
An intelligent anticollision function allows to operate more than one card in the field
simultaneously. The anticollision algorithm selects each card individually and ensures that
the execution of a transaction with a selected card is performed correctly without
interference from another card in the field.

8. Functional description
8.1 Block description
The MF1S70yyX 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 MF1S70yyX. No further external components are
necessary. Refer to the document
Ref. 1
for details on antenna design.

•
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 MF1S70yyX is used for
authentication and encryption of data exchange.
•
EEPROM: 4 kB is organized in 32 sectors of 4 blocks and 8 sectors of 16 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
MF1S70yyX. 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.
