SC23R01
8K-BIT CONTACTLESS IC CARD
DESCRIPTION
SC23R01 is a smart card module utilizing CMOS EEPROM
technology. It is a multi-application functionality smart card with 1024
bytes EEPROM memory. Its embedded crypto and communication
modules can protect the system from any kind of tampering and make
it attractive in ticketing applications.
FEATURES
* 1024 X 8 bit EEPROM;
* Operating frequency: 13.56MHz; baud rate: 106Kbit/s;
* Contactless transmission of data and not need external power
supply;
ORDERING INFORMATION
* Operating distance: up to 10cm;
* High security data transmission;
* 16 independence sectors which support manifold applications;
* For some key hierarchy system, each sector has two secret keys;

FUNCTION DESCRIPTION
1. RF interface and read/write device
1.1 Request REQ STD/ALL
The communication protocol of SC23R01 is complied with the ISO14443A. When the card is positioned in the
proximity of the read/write device (RWD), the RWD sends the REQ STD/ALL command to confirm whether the
card is SC23R01.
1.2 Anti-collision loop
When there are several cards in the operating rang of the RWD, the anticollision algorithm selects one card for
further transaction. The unselected card return to the standby mode and wait for a new request command. In this
course, it will return the serial number of the card.
1.3 Select card
Select the serial number of the selected card, the card returns the answer to select code (=08H).
1.4 3 Pass authentication
After selecting the card, the RWD specifies the memory location which needs access, and uses the
www.DataShceoertr4eUs.pconmding key for 3 pass authentication. After authenticating successfully, all memory operations are
encrypted. (for selecting another sector, the key should be authenticated again) .
1.5 Memory operations
After authentication, the following operation may be performed:
Read: read block.
Write: write block.
Decrement: decrease the content of a block and store the result in a data register.
Increment: increase the content of a block and store the result in a data register.
Transfer: write the content of data register to a value block.
Restore: read the content of the value block to the data register.
Halt: set the card in the halt mode.
