General description
NXP Semiconductors developed the MIFARE Ultralight EV1 MF0ULx1 for use in a
contactless smart ticket, smart card or token in combination with a Proximity Coupling
Device (PCD). The MF0ULx1 is designed to work in an ISO/IEC 14443 Type A compliant
environment (see [1]). The target applications include single trip or limited use tickets in
public transportation networks, loyalty cards or day passes for events. The MF0ULx1
serves as a replacement for conventional ticketing solutions such as paper tickets,
magnetic stripe tickets or coins. It is also a perfect ticketing counterpart to contactless
card families such as MIFARE DESFire or MIFARE Plus.
The MIFARE Ultralight EV1 is succeeding the MIFARE Ultralight ticketing IC and is fully
functional backwards compatible. Its enhanced feature and command set enable more
efficient implementations and offer more flexibility in system designs.
The mechanical and electrical specifications of MIFARE Ultralight EV1 are tailored to
meet the requirements of inlay and paper ticket manufacturers.
In this document the term „MIFARE Ultralight card“ refers to a MIFARE Ultralight ICbased contactless card.
1.1 Contactless energy and data transfer
In a contactless system, the MF0ULx1 is connected to a coil with a few turns. The
MF0ULx1 fits the TFC.0 (Edmondson) and TFC.1 (ISO) ticket formats as defined in Ref.
8.
The MF0ULx1 chip, which is available with 17 pF or 50 pF on-chip resonance capacitor,
supports both TFC.1 and TFC.0 ticket formats.
1.2 Anticollision
An intelligent anticollision function allows more than one card to operate in the field
simultaneously. The anticollision algorithm selects each card individually. It ensures
that the execution of a transaction with a selected card is performed correctly without
interference from another card in the field.

Functional description
8.1 Block description
The MF0ULx1 chip consists of a 640-bit or a 1312-bit EEPROM, RF interface and Digital
Control Unit (DCU). Energy and data are transferred via an antenna consisting of a
coil with a few turns which is directly connected to the MF0ULx1. No further external
components are necessary. Refer to Ref. 2 for details on antenna design.
• RF interface:
– modulator/demodulator
– rectifier
– clock regenerator
– Power-On Reset (POR)
– voltage regulator
• Anticollision: multiple cards may be selected and managed in sequence
• Command interpreter: processes memory access commands that the MF0ICU1
supports
• EEPROM interface
• EEPROM: 640 bit, organized in 20 pages of 4 byte per page.
– 208 bit reserved for manufacturer and configuration data
– 16 bit used for the read-only locking mechanism
– 32 bit available as OTP area
– 384 bit user programmable read/write memory
• EEPROM: 1312 bit, organized in 41 pages of 4 byte per page.
– 208 bit reserved for manufacturer and configuration data
– 31 bit used for the read-only locking mechanism
– 32 bit available as OTP area
– 1024 bit user programmable read/write memory
8.2 RF interface
The RF-interface is based on the ISO/IEC 14443 Type A standard for contactless smart
cards.
During operation, the reader generates an RF field. This RF field must always be present
(with short pauses for data communication), as it is used for the power supply of the card.
For both directions of data communication, there is one start bit at the beginning of each
frame. Each byte is transmitted with an odd parity bit at the end. The LSB of the byte with
the lowest address of the selected block is transmitted first. The maximum length of a
PCD to PICC frame is 208 bits (21 data bytes + 2 CRC bytes = 20×9 + 2×9 + 1 start bit).
The maximum length for a fixed size PICC to PCD frame is 307 bits (32 data bytes + 2
CRC bytes = 32×9 + 2×9 + 1 start bit). The FAST_READ response has a variable frame
length depending on the start and end address parameters. When issuing this command,
take into account the maximum frame length that the PCD supports.
For a multi-byte parameter, the least significant byte is always transmitted first. As an
example, take reading from the memory using the READ command. Byte 0 from the
addressed block is transmitted first after which, byte 1 to byte 3 are transmitted. The
same sequence continues for the next block and all subsequent blocks.

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 Communication principle
The reader initiates the commands and the Digital Control Unit of the MF0ULx1 controls
them. The command response is depending on the state of the IC and for memory
operations also on the access conditions valid for the corresponding page.

Remark: In all states, the command interpreter returns to the idle state on receipt of an
unexpected command. If the IC was previously in the HALT state, it returns to that state
Remark: The VCSL command is only allowed in the ACTIVE state
Figure 4. State diagram
8.4.1 IDLE state
After a power-on reset (POR), the MF0ULx1 switches to the IDLE state. It only exits this
state when a REQA or a WUPA command is received from the PCD. Any other data
received while in this state is interpreted as an error and the MF0ULx1 remains in the
IDLE state.
Refer to Ref. 4 for implementation hints for a card polling algorithm that respects relevant
timing specifications from ISO/IEC 14443 Type A.
After a correctly executed HLTA command, for example out of the ACTIVE or
AUTHENTICATED state, the default waiting state changes from IDLE to HALT. This
state can then be exited with a WUPA command only.

MIFARE Ultralight EV1 - Contactless ticket IC
8.4.2 READY1 state
In this state, the PCD resolves the first part of the UID (3 bytes) using the
ANTICOLLISION or SELECT commands in cascade level 1. This state is exited correctly
after execution of either of the following commands:
• SELECT command from cascade level 1: the PCD switches the MF0ULx1 into
READY2 state where the second part of the UID is resolved.
• READ command (from address 0): all anticollision mechanisms are bypassed and the
MF0ULx1 switches directly to the ACTIVE state.
Remark: If more than one MF0ULx1 is in the PCD field, a READ command from
address 0 selects all MF0ULx1 devices. In this case, a collision occurs due to the
different serial numbers. Any other data received in the READY1 state is interpreted as
an error. Depending on its previous state, the MF0ULx1 returns to either the IDLE state
or HALT state.
8.4.3 READY2 state
In this state, the MF0ULx1 supports the PCD in resolving the second part of its UID (4
bytes) with the cascade level 2 ANTICOLLISION command. This state is usually exited
using the cascade level 2 SELECT command.
Alternatively, READY2 state can be skipped using a READ command (from address 0)
as described for the READY1 state.
Remark: The response of the MF0ULx1 to the cascade level 2 SELECT command is the
select acknowledge (SAK) byte. In accordance with ISO/IEC 14443, this byte indicates
if the anticollision cascade procedure has finished. It also defines the type of device
selected for the MIFARE product architecture platform. The MF0ULx1 is now uniquely
selected and only this device communicates with the PCD even when other contactless
devices are present in the PCD field. If more than one MF0ULx1 is in the PCD field, a
READ command from address 0 selects all MF0ULx1 devices. In this case, a collision
occurs due to the different serial numbers. Any other data received when the device is in
this state is interpreted as an error. Depending on its previous state the MF0ULx1 returns
to either the IDLE state or HALT state.
8.4.4 ACTIVE state
All memory operations and other functions like the originality signature read-out are
operated in the ACTIVE state.
The ACTIVE state is gratefully exited with the HLTA command and upon reception the
MF0ULx1 transits to the HALT state. Any other data received when the device is in this
state is interpreted as an error. Depending on its previous state the MF0ULx1 returns to
either the IDLE state or HALT state.
The MF0ULx1 transits to the AUTHENTICATED state after successful password
verification using the PWD_AUTH command.
8.4.5 AUTHENTICATED state
In this state, all operations on memory pages, which are configured as password
verification protected, can be accessed.
The AUTHENTICATED state is gratefully exited with the HLTA command and upon
reception the MF0ULx1 transits to the HALT state. Any other data received when the

device is in this state is interpreted as an error. Depending on its previous state the
MF0ULx1 returns to either the IDLE state or HALT state.
8.4.6 HALT state
The HALT and IDLE states constitute the two wait states implemented in the MF0ULx1.
An already processed MF0ULx1 can be set into the HALT state using the HLTA
command. In the anticollision phase, this state helps the PCD to distinguish between
processed cards and cards yet to be selected. The MF0ULx1 can only exit this state on
execution of the WUPA command. Any other data received when the device is in this
state is interpreted as an error and the MF0ULx1 state remains unchanged. Refer to Ref.
4 for correct implementation of an anticollision procedure based on the IDLE and HALT
states and the REQA and WUPA commands.
8.5 Memory organization
The EEPROM memory is organized in pages with 4 bytes per page. The MF0UL11
variant has 20d pages and the MF0UL21 variant has 41d pages in total. The memory
organization can be seen in Figure 5 and Figure 6, the functionality of the different
memory sections is described in the following sections.

8.5.2 Lock byte 0 and byte 1
The bits of byte 2 and byte 3 of page 02h represent the field programmable read-only
locking mechanism. Each page from 03h (OTP) to 0Fh can be individually locked by
setting the corresponding locking bit Lx to logic 1 to prevent further write access. After
locking, the corresponding page becomes read-only memory.
The three least significant bits of lock byte 0 are the block-locking bits. Bit 2 deals
with pages 0Ah to 0Fh, bit 1 deals with pages 04h to 09h and bit 0 deals with page
03h (OTP). Once the block-locking bits are set, the locking configuration for the
corresponding memory area is frozen.

Figure 8. Lock bytes 0 and 1
For example if BL15-10 is set to logic 1, then bits L15 to L10 (lock byte 1, bit[7:2]) can
no longer be changed. A WRITE command or COMPATIBILITY_WRITE command to
page 02h, sets the locking and block-locking bits. Byte 2 and byte 3 of the WRITE or
COMPATIBILITY_WRITE command, and the contents of the lock bytes are bit-wise
OR’ed and the result then becomes the new content of the lock bytes. This process is
irreversible. If a bit is set to logic 1, it cannot be changed back to logic 0.
The contents of bytes 0 and 1 of page 02h are unaffected by the corresponding data
bytes of the WRITE or COMPATIBILITY_WRITE command.
The default value of the static lock bytes is 00 00h.
Any write operation to the lock bytes 0 and 1, features anti-tearing support.
Remark: Setting a lock bit to 1 immediately prevents write access to the respective page
8.5.3 Lock byte 2 to byte 4
To lock the pages of the MF0UL21 starting at page address 10h onwards, the lock bytes
2-4 located in page 24h are used. Those three lock bytes cover the memory area of 80
data bytes. The granularity is 2 pages, compared to a single page for the first 512 bits as
shown in Figure 9.
Remark: Set all bits marked with RFUI to 0, when writing to the lock bytes.

MIFARE Ultralight EV1 - Contactless ticket IC
8.6 Password verification protection
The memory write or read/write access to a configurable part of the memory can be
constrained to a positive password verification. The 32-bit secret password (PWD)
and the 16-bit password acknowledge (PACK) are typically programmed into the
configuration pages at ticket issuing or personalization. The use of a chip individual
password acknowledge response raises the trust level on the PCD side into the PICC.
The AUTHLIM parameter specified in Section 8.5.6 can be used to limit the negative
verification attempts.
In the initial state of the MF0ULx1, an AUTH0 value of FFh disables password protection.
PWD and PACK are freely writable in this state. Access to the configuration pages and
any part of the user memory, can be restricted by setting AUTH0 a page address within
the available memory space. The page address is the first one protected.
Remark: Note that the password verification method available in then MF0ULx1 does not
offer a high security protection. It is an easy and convenient way to prevent unauthorized
memory access. If a higher level of protection is required, cryptographic methods on
application layer can be used to increase overall system security.
8.6.1 Programming of PWD and PACK
Program the 32-bit PWD and the 16-bit PACK into the configuration pages, see Section
8.5.6. The password as well as the password acknowledge, are written LSByte first. This
byte order is the same as the byte order used during the PWD_AUTH command and its
response.
The PWD and PACK bytes can never be read out of the memory. Instead of transmitting
the real value on any valid READ or FAST_READ command, only 00h bytes are replied.
If the password verification does not protect the configuration pages, PWD and PACK
can be written with normal WRITE and COMPATIBILITY_WRITE commands.
If the password verification protects the configuration pages, PWD and PACK can only
be written after a successful PWD_AUTH command.
The PWD and PACK are writable even if the CFGLCK bit is set to 1b. Therefore it is
strongly recommended to set AUTH0 to the page where the PWD is located after the
password has been written. This page is 12h for the MF0UL11 and 27h for the MF0UL21.
Remark: To improve the overall system security, it is strongly recommended to diversify
the password and the password acknowledge using a die individual parameter, that is,
the 7-byte UID available on the MF0ULx1.
8.6.2 Limiting negative verification attempts
To prevent brute-force attacks on the password, the maximum allowed number of
negative password verification attempts can be set using AUTHLIM. This mechanism
is disabled by setting AUTHLIM to a value of 000b which is also the initial state of the
MF0ULx1.
If AUTHLIM is not equal to 000b, each negative authentication verification is internally
counted. The count operation features anti-tearing support. As soon as this internal
counter reaches the number specified in AUTHLIM, any further negative password
verification leads to a permanent locking of the protected part of the memory for the
specified access modes. Independent, whether the provided password is correct or not,
each subsequent PWD_AUTH fails.

MF0ULX1
NXP Semiconductors
MIFARE Ultralight EV1 - Contactless ticket IC
Any successful password verification, before reaching the limit of negative password
verification attempts, resets the internal counter to zero.
8.6.3 Protection of special memory segments
The configuration pages can be protected by the password authentication as well. The
protection level is defined with the PROT bit.
The protection is enabled by setting the AUTH0 byte to a value that is within the
addressable memory space.
All counters can always be incremented and read without prior password verification.
8.7 Counter functionality
The MF0ULx1 features three independent 24-bit one-way counters. These counters are
located in a separate part of the NVM which is not directly addressable using READ,
FAST_READ, WRITE or COMPATIBILITY_WRITE commands. The actual value can
be retrieved by using the READ_CNT command, the counters can be incremented
with the INCR_CNT command. The INCR_CNT command features anti-tearing
support, thus no undefined values originating from interrupted programing cycles are
possible. Either the value is unchanged or the correct, incremented value is correctly
programmed into the counter. The occurrence of a tearing event can be checked using
the CHECK_TEARING_EVENT command.
In the initial state, the counter values are set to 000000h.
The counters can be incremented by an arbitrary value. The incremented value is
valid immediately and does not require a RF reset or re-activation. Once counter value
reaches FFFFFFh and an increment is performed via a valid INCR_CNT command, the
MF0ULx1 replies a NAK. If the sum of the addressed counter value and the increment
value in the INCR_CNT command is higher than FFFFFFh, the MF0ULx1 replies a NAK
and does not update the respective counter.
An increment by zero (000000h) is always possible, but does not have any impact on the
counter value.
8.8 Originality function
The MF0ULx1 features a cryptographically supported originality check. With this
feature, it is possible to verify with a certain probability, that the ticket is using an NXP
Semiconductors manufactured silicon. This check can also be performed on personalized
tickets.
Each MF0ULx1 holds a 32-byte cryptographic signature based on elliptic curve
cryptography. This signature can be retrieved using the READ_SIG command and can
be verified using the corresponding ECC public key in the PCD.
8.9 Virtual Card Architecture Support
The MF0ULx1 supports the virtual card architecture by replying to a Virtual Card Select
Last (VCSL) command with a virtual card type identifier. The VCTID that is replied can be
programmed in the configuration pages. It enables infrastructure supporting this feature
to process MIFARE product-based cards across different MIFARE families in a common
way.

All given command and response transmission times refer to the data frames including
start 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 unmodulated carrier). A PICC data 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. 1 as an integer
n which specifies the PCD to PICC frame delay time. The frame delay time from PICC
to PCD has a minimum n of 9. The maximum command response time is specified as
a time-out value. Depending on the command, the TACK value specified for command
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 more details, refer to Ref. 1.

The user memory for the MF0UL11 is 48 bytes. This memory size is between 32d bytes
and 64d bytes. Therefore, the most significant 7 bits of the value 0Bh, are interpreted as
5d and the least significant bit is 1b.
The user memory for the MF0UL21 is 128 bytes. This memory size is exactly 128d.
Therefore, the most significant 7 bits of the value 0Eh, are interpreted as 7d and the least
significant bit is 0b.
10.2 READ
The READ command requires a start page address, and returns the 16 bytes of four
MIFARE Ultralight pages. For example if address (Addr) is 03h then pages 03h, 04h,
05h, 06h are returned. A rollover mechanism is implemented if the READ command
address is near the end of the accessible memory area. This rollover mechanism is also
used when at least part of the addressed pages is within a password protected area. For
details on those cases see the description below. The command structure is shown in
Figure 13 and Table 16.

MF0ULX1
NXP Semiconductors
MIFARE Ultralight EV1 - Contactless ticket IC
In the initial state of the MF0ULx1, all memory pages are allowed as Addr parameter to
the READ command.
• page address 00h to 13h for the MF0UL11
• page address 00h to 28h for the MF0UL21
Addressing a memory page beyond the limits above results in a NAK response from the
MF0ULx1.
A roll-over mechanism is implemented to continue reading from page 00h once the
end of the accessible memory is reached. For example, reading from address 11h on a
MF0UL11 results in pages 11h, 12h, 13h and 00h being returned.
The following conditions apply if part of the memory is password protected for read
access:
• if the MF0ULx1 is in the ACTIVE state
– addressing a page which is equal or higher than AUTH0 results in a NAK response
– addressing a page lower than AUTH0 results in data being returned with the roll-over
mechanism occurring just before the AUTH0 defined page
• if the MF0ULx1 is in the AUTHENTICATED state
– the READ command behaves like on a MF0ULx1 without access protection
Remark: PWD and PACK values can never be read out of the memory. When reading
from the pages holding those two values, all 00h bytes are replied to the PCD instead.
10.3 FAST_READ
The FAST_READ command requires a start page address and an end page address and
returns the all n*4 bytes of the addressed pages. For example if the start address is 03h
and the end address is 07h then pages 03h, 04h, 05h, 06h and 07h are returned. If the
addressed page is outside of accessible area, the MF0ULx1 replies a NAK. For details
on those cases and the command structure, refer to Figure 14 and Table 18.
Table 19 shows the required timing.

In the initial state of the MF0ULx1, all memory pages are allowed as StartAddr parameter
to the FAST_READ command.
• page address 00h to 13h for the MF0UL11
• page address 00h to 28h for the MF0UL21
Addressing a memory page beyond the limits above results in a NAK response from the
MF0ULx1.
The EndAddr parameter must be equal to or higher than the StartAddr.
The following conditions apply if part of the memory is password protected for read
access:
• if the MF0ULx1 is in the ACTIVE state
– if any requested page address is equal or higher than AUTH0 a NAK is replied
• if the MF0ULx1 is in the AUTHENTICATED state
– the FAST_READ command behaves like on a MF0ULx1 without access protection
Remark: PWD and PACK values can never be read out of the memory. When reading
from the pages holding those two values, all 00h bytes are replied to the PCD instead.
Remark: The FAST_READ command is able to read out the whole memory with one
command. Nevertheless, receive buffer of the PCD must be able to handle the requested
amount of data as there is no chaining possibility.
10.4 WRITE
The WRITE command requires a block address, and writes 4 bytes of data into the
addressed MIFARE Ultralight EV1 page. The WRITE command is shown in Figure 15
and Table 20.
Table 21 shows the required timing.

The MF0ULx1 features tearing protected write operations to specific memory content.
The following pages are protected against tearing events during a WRITE operation:
• page 2 containing lock bits
• page 3 containing OTP bits
• page 36d containing the additional lock bits for the MF0UL21
10.5 COMPATIBILITY_WRITE
The COMPATIBILITY_WRITE command is implemented to accommodate the
established MIFARE Classic PCD infrastructure. Even though 16 bytes are transferred
to the MF0ULx1, only the least significant 4 bytes (bytes 0 to 3) are written to
the specified address. Set all the remaining bytes, 04h to 0Fh, to logic 00h. The
COMPATIBILITY_WRITE command is shown in Figure 16 and Table 20.

In the initial state of the MF0ULx1, the following memory pages are valid Addr
parameters to the COMPATIBILITY_WRITE command.
• page address 02h to 13h for the MF0UL11
• page address 02h to 28h for the MF0UL21
Addressing a memory page beyond the limits above results in a NAK response from the
MF0ULx1.
Pages which are locked against writing cannot be reprogrammed using any write
command. The locking mechanisms include lock bits as well as the locking of the
configuration pages.
The following conditions apply if part of the memory is password protected for write
access:
• if the MF0ULx1 is in the ACTIVE state
– writing to a page which address is equal or higher than AUTH0 results in a NAK
response
• if the MF0ULx1 is in the AUTHENTICATED state
– the COMPATIBILITY_WRITE command behaves the same as on a MF0ULx1 without
access protection
The MF0ULx1 features tearing protected write operations to specific memory
content. The following pages are protected against tearing events during a
COMPATIBILITY_WRITE operation:
• page 2 containing lock bits
• page 3 containing OTP bits
• page 36d containing the additional lock bits for the MF0UL21
10.6 READ_CNT
The READ_CNT command is used to read out the current value of one of the 3 one-way
counters of the MF0ULx1. The command has a single argument specifying the counter
number and returns the 24-bit counter value of the corresponding counter. The counters
are always readable, independent on the password protection settings. The command
structure is shown in Figure 18 and Table 24.

The IncrValue argument is a 4-byte field to support the same command structure as
the WRITE command. As the counter width is only 3 byte, the last transmitted, most
significant byte is ignored.
Any increment value is allowed. Nevertheless, the final counter value is FFFFFFh. No
further increment is possible after the final value is reached. Also, trying to increment the
current value by a number which would exceed the final value leads to a NAK response
and the counter remains unchanged. An increment by 0 is allowed but leaves the counter
unchanged.
The order of bytes in the increment argument follows the same order that the bytes
are sent via the communication interface. This means from the LSbyte (IncrValue0) to
MSbyte (IncValue3), where the last valid byte is actually IncrValue2. It is in line with
the arguments consisting of multiple bytes for other commands. As an example, an
increment of the counter 00h by 01h, is formulated as INCR CNT 00 01 00 00 00.
The INCR_CNT command features anti-tearing support.

10.8 PWD_AUTH
A protected memory area can be accessed only after a successful password verification
using the PWD_AUTH command. The AUTH0 configuration byte defines the protected
area. It specifies the first page that the password mechanism protects. The level of
protection can be configured using the PROT bit either for write protection or read/
write protection. The PWD_AUTH command takes the password as parameter and, if
successful, returns the password authentication acknowledge, PACK. By setting the
AUTHLIM configuration bits to a value larger than 000b, the number of unsuccessful
password verifications can be limited. Each unsuccessful authentication is then counted
in a counter featuring anti-tearing support. After reaching the limit of unsuccessful
attempts, the memory access specified in PROT, is no longer possible. The PWD_AUTH
command is shown in Figure 20 and Table 28.

10.10 CHECK_TEARING_EVENT
The CHECK_TEARING_EVENT command enables the application to identify if a tearing
event happened on a specified counter element. It takes the counter number as single
argument and returns a specified valid flag for this counter. If the returned valid flag is
not equal to the predefined value, a tearing event happened. Note, although a tearing
event might have happened on the counter, a valid value corresponding to the last valid
counter status is still available using the READ_CNT command. The command structure
is shown in Figure 22 and Table 32.

The valid flag for normal operation is BDh. If any other value than BDh is replied on the
CHECK_TEARING_EVENT command, a tearing event has happened on the addressed
counter.
The application can use this information to base business logic decisions on.
10.11 VCSL
The VCSL command is used to enable a unique identification and selection process
across different MIFARE product-based cards and card implementations on mobile
devices. The command requires a 16-byte installation identifier IID and a 4-byte PCD
capability value as parameters. The parameters are present to support compatibility to
other MIFARE product-based devices but are not used or checked inside the MF0ULx1.
Nevertheless, the number of bytes is checked for correctness. The answer to the VCSL
command is the virtual card type identifier VCTID. This identifier indicates the type of
card or ticket. Using this information, the reader can decide whether the ticket belongs to
the installation or not. The command structure is shown in Figure 23 and Table 34.
Table 35 shows the required timing.
