1. General description
NXP Semiconductors has developed the MIFARE Classic MF1S70yyX/V1 to be used in a
contactless smart card according to ISO/IEC 14443 Type A.
The MIFARE Classic EV1 4K MF1S70yyX/V1 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.
1.2 Simple integration and user convenience
The MF1S70yyX/V1 is designed for simple integration and user convenience which allows
complete ticketing transactions to be handled in less than 100 ms.
1.3 Security and privacy
•
Manufacturer programmed 7-byte UID or 4-byte NUID identifier for each device
• Random ID support
• Mutual three pass authentication (ISO/IEC DIS 9798-2)
• Individual set of two keys per sector to support multi-application with key hierarchy

8. Functional description
8.1 Block description
The MF1S70yyX/V1 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/V1. 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 MF1S70yyX/V1 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/V1. 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.
