8. Functional description
8.1 Block description
The MF1S50yyX/V1 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/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 acce ss to a block is only possible via the two keys specified for each
block
Control and Arithmetic Lo gic Unit: V alue s are stored in a special redundant forma t and
can be incremented and decremented
EEPROM interface
Crypto unit: The CRYPTO1 stream cipher of the MF1S50yyX/V1 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 in itiate d by the rea der and co ntrolled by the Digital Control Unit of the
MF1S50yyX/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 unse lected 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.

Remark: For the 4-byte non-uni que ID product versions, the identifier retrieved from the
card is not defined to be un ique . F or fu rther information regarding handling of no n- uniq ue
identifiers see Ref. 6.
8.2.3 Select card
With the select card command the reader selects one individual card for authentication
and memory related operations. The card returns the Select AcKnowledge (SAK) code
which determines the type of the sele cted card, see Section 9.4. For further details refer to
the document Ref. 2.
8.2.4 Three pass authentication
After selection of a car d the reader specifie s the memory location of the following memory
access and uses the corresponding key for the three pa ss authentication proced ure. Af ter
a successful authentication all commands and responses are encrypted.
Remark: The HLTA command needs to be sent encr ypted to the PICC after a successful
authentication in order to be accepted.

8.2.5 Memory operations
After authentication any of the following operations may be performed:
Read block
Write block
Decrement: Decrements the contents of a block and stores the result in the internal
Transfer Buffer
Increment: Increments the contents of a block and stores the result in the internal
Transfer Buffer
Restore: Moves the contents of a block into the internal Transfer Buffer
Transfer: Writes the contents of the internal Transfer Buffer to a value block
8.3 Data integrity
Following mechanisms are implemented in the contactless communication link between
reader and card to ensure very reliable data transmission:
16 bits CRC per block
Parity bits for each byte
Bit count checking
Bit coding to distinguish between “1”, “0” and “no information”
Channel monitoring (protocol sequence and bit stream analysis)
8.4 Three pass authentication sequence
1. The reader specifies the sector to be accessed and chooses key A or B.
2. The card reads the secret key and the access conditions fr om the secto r traile r. Then
the card sends a number as the challenge to the reader (pass one).
3. The reader calculates the response using the secret key an d additional input. The
response, together with a random challe nge from the reader , is then transmitted to the
card (pass two).
4. The card verifies the response of the reader by comparing it with its own challenge
and then it calculates the response to the challenge and transmits it (pass three).
5. The reader verifies the response of the card by comparing it to its own challenge.
After transmission of the first random challenge the communication between card and
reader is encrypted.

MIFARE Classic EV1 1K - Mainstream contactless smart card IC
8.5 RF interface
The RF-interface is according to the standard for contactless smart cards
ISO/IEC 14443A.
For operation, the carrier field from the reader always needs to be present (with short
pauses when transmitting), as it is used for the power supply of the card.
For both directions of data communication there is only one start bit at the beginning of
each frame. Each byte is transmitted with a parity bit (odd parity) at the end. The LSB of
the byte with the lowest address of the selected block is transmitted first. The maximum
frame length is 163 bits (16 data bytes + 2 CRC bytes = 16 9 + 2 9 + 1 start bit).
8.6 Memory organization
The 1024 8 bit EEPROM memory is organized in 16 sectors of 4 blocks. One block
contains 16 bytes.

8.6.1 Manufacturer block
This is the first data block (block 0) of the first sector (sector 0). It contains the IC
manufacturer data. This block is programmed and write protected in the production test.
The manufacturer block is shown in Figure 6 and Figure 7 for the 4-byte NUID a nd 7-byte
UID version respectively.
8.6.2 Data blocks
All sectors contain 3 blocks of 16 bytes for storing data (Sector 0 contains only two data
blocks and the read-only manufacturer block).
The data blocks can be configured by the access bits as
read/write blocks
value blocks
Value blocks can be used for e.g. electronic purse applications, where additional
commands like increment and decrement for direct control of the stored value are
provided
A successful authentication has to be performed to allow any memory operation.
Remark: The default content of the data blocks at delivery is not defined.
8.6.2.1 Value blocks
Value blocks allow performing electronic purse functions (valid commands are: read,
write, increment, decrement, restore, transfer). Value blocks have a fixed data format
which permits error detection and correction and a backup management.
A value block can only be generated through a write operation in value block format:
Value: Signifies a signed 4-byte value. The lowest significant byte of a value is stor ed
in the lowest address byte. Negative values are stored in standard 2´s complement
format. For reasons of data integrity and security, a value is stored three times, twice
non-inverted and once inverted.

Adr: Signifies a 1-byte add ress, which can be used to save the storage address of a
block, when implementing a powerful backup management. The address byte is
stored four times, twice inverted and non-inverted. During increment, decrement,
restore and transfer operations the address remains unchanged. It can only be
altered via a write com m a nd .
An example of a valid value block format for the decimal value 1234567d and the block
address 17d is shown in Table 4. First, the decimal value has to be converted to the
hexadecimal representation of 0012D687h. The LSByte of the hexadecimal value is
stored in Byte 0, the MSByte in Byte 3. The bit inverted hexadecimal representation of th e
value is FFED2978h where the LSByte is stored in Byte 4 and the MSByte in Byte 7.
The hexadecimal value of the a ddress in the example is 11h, the bit inverted hexadecimal
value is EEh.
8.6.3 Sector trailer
The sector trailer is the last block (block 3) in one sector. Each sector has a sector trailer
containing the
secret keys A (mandatory) and B (optional), which return logical “0”s when read and
the access conditions for the blocks of that sector , which are stored in bytes 6...9. The
access bits also specify the type (data or value) of the data blocks.
If key B is not ne eded, the last 6 bytes of the sector trailer can be used a s dat a bytes. The
access bits for the sector trailer have to be configured accordingly, see Section 8.7.2.
Byte 9 of the sector trailer is available for user data. For this byte the same access rights
as for byte 6, 7 and 8 apply.
When the sector trailer is read, the key bytes are blanked out by return ing logical zeros. If
key B is configured to be readable, the data stored in bytes 10 to 15 is returned, see
Section 8.7.2.
All keys are set to FFFF FFFF FFFFh at chip delivery and the bytes 6, 7 and 8 are set to
FF0780h.

8.7.1 Access conditions
The access conditions for every data block and sector trailer are defined by 3 bits, which
are stored non-inverted and inverted in the sector trailer of the specified sector.
The access bits control the rights of memory access using the secret keys A and B. The
access conditions may be altered, provided one knows the relevant key and the current
access condition allows this operation.
Remark: With each memory access the internal logic verifies the format of the access
conditions. If it detects a format violation the whole sector is irreversibly blocked.
Remark: In the following desc rip tio n the access bits are mentione d in the no n-i nv er te d
mode only.
The internal logic of the MF1S50yyX/V1 ensures that the commands are executed only
after a successful authentication.

8.7.2 Access conditions for the sector trailer
Depending on the access bits for the sector trailer (block 3) the read/write access to the
keys and the access bits is specified as ‘never’, ‘key A’, ‘key B’ or key A|B’ (key A or
key B).
On chip delivery the access conditions for the sector trailers and key A are predefined as
transport configuration. Since key B may be read in th e transport configuration, new cards
must be authenticated with key A. Since the access bits them selve s can al so be bl ocke d,
special care has to be taken during the personalization of cards.
[1] For this access condition key B is readable and may be used for data

8.7.3 Access conditions for data blocks
Depending on the access bits for data blocks (blocks 0...2) the read/write access is
specified as ‘never’, ‘key A’, ‘key B’ or ‘key A|B’ (key A or key B). The setting of the
relevant access bits defines the application and the corresponding applicable commands.
Read/write block: the operations read and write are allowed.
Value block: Allows the additional value operations incre ment, decrement, transfer
and restore. With access condition ‘001’ only read and decrement are possible which
reflects a non-rechargeab le card. For access conditio n ‘110’ recharging is possible b y
using key B.
Manufacturer block: the read-only condition is not affected by the access bits setting!
Key management: in transport configuration key A must be used for authentication
[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.

9.2 Timings
The timing shown in this document are not to scale and values are rounded to 1 s.
All given times refer to the data frames including star t 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 unmod ulated carrier). A PICC dat a
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 s. Th e ma xim u m co mm a nd res po ns e ti me is specified as a time-out
value. Depending on the command, the TACK value specified for comma nd 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 mor e details refer to Ref. 3 and Ref. 4.
Remark: Due to the coding of commands, the measured timings usually excludes (a par t
of) the end of communication. Consider this factor when comparing the specified with the
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 1444 3 start s with LSBit = bit 1, but not LSBit =
bit 0. So one byte counts bit 1 to 8 instead of bit 0 to 7.

10. UID Options and Handling
The MF1S50yyX/V1 product family offers two delivery options for the UID which is stored
in block 0 of sector 0.
7-byte UID
4-byte NUID (Non-Unique ID)
This section describes the MIFARE Classic MF1S50yyX/V1 operation when using one of
the 2 UID options with re sp ec t to car d selection, authentic ati on and personalization. See
also Ref. 6 for details on how to handle UIDs and NUIDs with MIFARE Classic products.
10.1 7-byte UID Operation
All MF1S500yXDyy products are featuring a 7-byte UID. This 7-byte UID is stored in
block 0 of sector 0 as shown in Figure 7. The behaviour during anti-collision, selection and
authentication can be configured during personalization for this UID variant.
10.1.1 Personalization Options
The 7-byte UID variants of the MF1S50yyX/V1 can be oper ated with four diffe rent
functionalities, denoted as UIDFn (UID Functionality n).
1. UIDF0: anti-collision and selection with the double size UID according to ISO/IEC
14443-3
2. UIDF1: anti-collision and selection with the double size UID according to ISO/IEC
14443-3 and optional usage of a selection process shortcut
3. UIDF2: anti-collision and selection with a single size random ID according to ISO/IEC
14443-3
4. UIDF3: anti-collision and selection with a single size NUID according to ISO/IEC
14443-3 where the NUID is calculated out of the 7-byte UID
The anti-collision and selection procedure and the implications on the authentication
process are detailed in Section 10.1.2 and Section 10.1.3.
The default configuration at delivery is option 1 which enables the ISO/IEC 14443-3
compliant anti-collision and selection. This configuration can be changed using the
‘Personalize UID Usage’ command. The execution of this command requires an
authentication to sector 0. Once this command has been issued and accepted by the
PICC, the configuration is automatically locked. A subsequently issued ‘Personalize UID
Usage’ command is not executed and a NAK is replied by the PICC.
Remark: As the configuration is changeable at delivery, it is strongly recommended to
send this command at personalization of the card to prevent unwanted changes in the
field. This should also be done if the default configuration is used.
Remark: The configuration becomes effective only after PICC unselect or PICC field
reset.

10.1.2 Anti-collision and Selection
Depending on the chosen personalization option there are certain possibilities to perform
anti-collision and selection. To bring the MIFARE Classic into the ACTIVE state according
to ISO/IEC 14443-3, the following sequences are available.
Sequence 1: ISO/IEC 14443-3 compliant anti-collision and selection using the cascade
level 1 followed by the cascade level 2 SEL command
Sequence 2: using cascade level 1 anti-collision and selection procedure followed by a
Read command from block 0
Sequence 3: ISO/IEC 14443-3 compliant anti-collision and selection using the cascade
level 1 SEL command
Remark: The Read from Block 0 in Sequence 2 does not require a pri or auth entication to
Sector 0 and is transmit te d in pla in da ta. For all other sequences, the readout from Block
0 in Sector 0 is encrypted and requires an authentication to that sector.
Remark: The settin gs done with Perso nalize UID Usage do n ot change the ATQA coding.

MIFARE Classic EV1 1K - Mainstream contactless smart card IC
10.1.3 Authentication
During the authentication process, 4-byte of the UID are pa ssed on to the MIF ARE Classic
Authenticate command of the contactless reader IC. Depending on the activation
sequence, those 4-byte are chosen differently. In general, the input parameter to the
MIFARE Classic Authenticate command is the set of 4 bytes retrieved during the last
cascade level from the ISO/IEC 14443-3 Type A anticollision.
10.2 4-byte UID Operation
All MF1S503yXDyy products are featuring a 4-byte NUID. This 4-byte NUID is stored in
block 0 of sector 0 as shown in Figure 6.
10.2.1 Anti-collision and Selection
The anti-collision and selection process for the product variants featuring 4-byte NUIDs is
done according to ISO/IEC 14443-3 Type A using cascade level 1 only.
10.2.2 Authentication
The input parameter to the MIFARE Classic Authenticate command is the full 4-byte UID
retrieved during the anti-collision procedure. This is the same as for the activation
Sequence 3 in the 7-byte UID variant.
11. Load Modulation Strength Option
The MIF ARE Classic EV11K features the possibility to set the load modulation strength to
high or normal. The default level is set to a high modulation strength and it is
recommended for optimal performance to maintain this level and only switch to the low
load modulation strength if the contactless system requires it.
Remark: The configuration becomes effective only after a PICC unselect or a PICC field
reset. The configuration can be changed multiple times by asserting the command.
Remark: The MIFARE Classic EV1 1K needs to be authenticated to sector 0 with Key A
to perform the SET_MOD_TYPE command. The Access Bits for sector 0 are irrelevant.
