IMPORTANT: 1k-Bit Protected 1-Wire EEPROM with SHA-1 Engine. In the Buffer addresses [00h-7Fh] is the Data Memory (Read/Write); addresses [80h-87h] is 64-bit Secrets Memory (Write only) Read/Verify/Compare operations will have no effect on these addresses. Addresses [90h-97h] is 64-bit Registration Number (Read only) Program/Verify/Compare operations will have no effect on these addresses. The address range [88h-8Fh] also referred to as register page contains special function registers as well as general-purpose user-bytes and one factory byte. Once programmed to AAh or 55h most of these bytes become write-protected and can no longer be altered. All other codes will neither write-protect the address nor activate the special function associated to that particular byte. The factory byte will either read 55h or AAh. Typically this address will read 55h indicating that the addresses 8Eh and 8Fh are read/write user-bytes without any special function or locking mechanism. The code of AAh indicates that these two bytes are programmed with a 16-bit manufacturer ID and then write-protected at the factory. Please refer to device data sheet for details.
