ATA5577 [Preliminary]
Block 0 of page 0 contains the mode/configuration data, which is not transmitted during regular
read operations. Addressing block 0 will always affect block 0 of page 0 regardless of the page
selector. Block 7 of page 0 may be used as a write-protection password.
Block 3 of page 1 contains the option register, which is not transmitted during regular-read
operation.
Bit 0 of every block is the lock bit for that block. Once locked, the block (including the lock bit
itself) is not re-programmable via the RF field.
Blocks 1 and 2 of page 1 contain traceability data and are transmitted with the modulation
parameters defined in the configuration register after the opcode “11” is issued by the reader.
The traceability data blocks are programmed and locked by Atmel.
5. Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
