different serial number, ; transfer encrypted data and key protection.
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.

Memory map:
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.

SC23R01 provides high security: three pass authentication is before read/write operation; each card has
The secret key of the card is protected and cannot be read, which only the user knows and can amend it . The
The 8 k bits EEPROM is organized in 16 sectors with 4 blocks of 16 bytes each sector.
The block 3 of each sector contains the secret key A (6 bytes), access control condition (4 bytes) and secret
Block 3 configuration:
