Mainstream contactless smart card IC
8. Functional description
8.1 Memory organization
The 4 kB EEPROM memory (MF1PLUS80x) is organized in 32 sectors of 4 blocks and in
8 sectors of 16 blocks. The 2 kB EEPROM memory (MF1PLUS60x) is organized in
32 sectors of 4 blocks.
One block consists of 16 bytes.
8.1.1 Manufacturer block
The first data block (block 0) of the first sector (sector 0) contains the PICC manufacturer
data. This block is programmed and write protected during the production test.
8.1.2 Data blocks
Sectors 0
D
to 31
D
contain 3 blocks each and sectors 32
D
to 39
D
contain 15 blocks for data
storage. The data blocks can be configured using the access bits as:
• read/write blocks for storing binary data
• value blocks (only available in security level 1)
(1) CRYPTO1 key A in security level 0, 1, 2; plain text access byte in security level 3
