Functional description

8.1 Memory organization

The 4 kB EEPROM memory (MF1SPLUS80x) is organized in 32 sectors of 4 blocks and

in 8 sectors of 16 blocks. The 2 kB EEPROM memory (MF1SPLUS60x) 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 at production test.

8.1.2 Data blocks

storage. The data blocks can be configured using the access bits as:
