Ultralight Mifare Ultralight, a 512-bit contactless IC card, is a Mifare RF chip designed with a streamlined application model. On the basis of streamlining the storage capacity of the chip, this chip can be suppressed in a thinner size card, and the cost is more suitable for short-distance multi-station transportation system. The chip complies with the IEC/ISO 14443A interface protocol.

storage structure
The UltraLight card has 512 bits and is divided into 16 pages of 4 bytes each. The storage structure is as follows:
Page Number | Byte 0 | Byte 1 | Byte 2 | Byte 3 | Description |
0 | SN0 | SN1 | SN2 | BCC0 | Serial Number |
1 | SN3 | SN4 | SN5 | SN6 | Serial Number |
2 | BCC1 | Retention | Lock0 | Lock1 | Hold/Lock |
3 | OTP0 | OTP1 | OTP2 | OTP3 | OTP |
4 | Data0 | Data1 | Data2 | Data3 | Data read/write |
5 | Data4 | Data5 | Data6 | Data7 | Data read/write |
6 | Data8 | Data9 | Data10 | Data11 | Data read/write |
7 | Data12 | Data13 | Data14 | Data15 | Data read/write |
8 | Data16 | Data17 | Data18 | Data19 | Data read/write |
9 | Data20 | Data21 | Data22 | Data23 | Data read/write |
10 | Data24 | Data25 | Data26 | Data27 | Data read/write |
11 | Data28 | Data29 | Data30 | Data31 | Data read/write |
12 | Data32 | Data33 | Data34 | Data35 | Data read/write |
13 | Data36 | Data37 | Data38 | Data39 | Data read/write |
14 | Data40 | Data41 | Data42 | Data43 | Data read/write |
15 | Data44 | Data45 | Data46 | Data47 | Data read/write |
(1) Pages 0 and 1 store information such as the serial number of the card and are only readable. Calculated according to ISO/IEC14443-3 check digit as follows:
BCC0=CT⊕SN0⊕
BCC1=SN3 txt
(2) Page 2 is LOCK BYTES. Setting the bits corresponding to byte 2 and byte 3 can separately lock pages 3 to 15 as read-only areas.
Lock0
L 7 | L 6 | L 5 | L 4 | L OTP | BL 15-10 | BL 9-4 | BL OTP |
Lock1
L 15 | L 14 | L 13 | L 12 | L 11 | L 10 | L 9 | L 8 |
Lx Lock X Page is read-only
BLX locks the corresponding Lx bit
Note: Once the block-locking(BLX) bit is set to the locked configuration, the corresponding memory region will be frozen. For example, if the BL15-10 is set to 1, L15 to L10 can no longer be changed. Lock0 and Lock1 can be set by a write command. The written content and the current content are bit-or operations to obtain new content, and the initial value is 0. The process is irreversible. If a bit is set to 1, it can no longer be set to 0.
(3) Page 3 is OTP, that is, one-time programming, the initial value is 0. You can change its value by writing the command, writing the value and the current value of the bit or operation to get the new value. This process is irreversible. If a bit is set to 1, it will never be set back to 0.
Note: This memory area can be used as a one-time counter with a maximum value of 32.
(4) Pages 4 to 15 are user read/write areas, and the initial value is 0.
Function Description
UltraLight card is a one-way ticket contactless IC card.
Card instruction
reset--->request--->anticoll--->select--->read、write--->halt
Function Special Description
The UltraLight card operation function is the same as Mifare One, and the following points need to be explained:
U u Since the serial number of the UltraLight card is 7 bytes, the anti-collision function cannot return all the card serial numbers. If you want to obtain all the card serial numbers, please call the rf_get_snr function, which is a special function for the UltraLight card.
U u UltraLight card has no password, so there is no need to load the password and there is no authentication instruction.
The u u Rf_read function returns 16 bytes of data (I. e. 4 page), so the buffer given by the user must be greater than 16 bytes.
The u u Rf_write function writes 16 bytes of data. In fact, only the first 4 bytes of data are written to the specified address, and the remaining bytes can be filled with zeros.
u u UltraLight cards do not have value-added or impairment instructions.
u u Advanced functions are not supported.
