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 corresponding 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.

Data integrity In the contactless communication, the following measures ensure the data transmission: l anti-collision l 16 bits CRC error correction for each frame HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http: www.silan.com.cn REV:1.1 2006.10.31 Page 3 of 7 SC23R01 l parity bits for each byte l bit count checking l bit coding to distinguish between “1”, “0”or no information l channel monitoring(protocol sequence and bit stream analysis) 4. Security SC23R01 provides high security: three pass authentication is before read/write operation; each card has different serial number, ; transfer encrypted data and key protection. The secret key of the card is protected and cannot be read, which only the user knows and can amend it . The EEPROM is divided into 16 sectors, and each sector is with different key, user can set the key according to different sector (with multi-applications in one card). The RWD specifies the sector to be accessed only by verifying the key A or B. 5. Memory configuration and access condition The 8 k bits EEPROM is organized in 16 sectors with 4 blocks of 16 bytes each sector. Memory map: The block 3 of each sector contains the secret key A (6 bytes), access control condition (4 bytes) and secret key B(6 bytes), which is a specific block , other three blocks are data blocks; but the block 0 of the sector 0 used for store manufacture code and serial number, it is solidified and only readable. The data blocks can be configured two applications: read/write blocks and value blocks; the read/write block is used for store data, direct read and write; the value block is used for initialization, increment, decrement and value reading for direct control of the stored value.

If the RWD tries to authenticate any blocks with key B using gray line, the card will refuse any operation for memory after authentication.

HANDLING MOS DEVICES: Electrostatic charges can exist in many things. All of our MOS devices are internally protected against electrostatic discharge but they can be damaged if the following precautions are not taken: • Persons at a work bench should be earthed via a wrist strap. • Equipment cases should be earthed. • All tools used during assembly, including soldering tools and solder baths, must be earthed. • MOS devices should be packed for dispatch in antistatic/conductive containers.
