2.1.1

Data Zone

This zone of 512-bytes (4Kb) is part of the EEPROM array, and can be used for secure storage purposes.

Prior to locking the configuration section (using lockConfig), the Data zone is inaccessible and can be neither read nor

written. After configuration locking, the entire Data zone can be written using the Write command. If desired, the data to

be written can be encrypted.

In Table 2-1, “Byte Address” is the byte address within the Data zone for the first byte in the respective slot. Because all

Reads and Writes with the ATSHA204 are performed on a word (4-byte or 32-byte) basis, the word address in the table

below should be used for the address parameter passed to the Read and Write commands.
