Memory Resources
The memory of the DS28E05 consists of user memory,
administrative data, and a ROM ID.
size, access mode and purpose of the various memory
areas. Brackets around an access mode indicate possible
restrictions, such as write protection or read protection.
The memory is organized as 8 pages of 16 bytes each

the administrative data and the ROM ID. The function
memory locations 0074h to 0075h depends on the code
in the Factory Word (addresses 0076h to 0077h). The
Manufacturer ID can be a customer-supplied identification
code that assists the application software in identifying
the product the DS28E05 is associated with. Contact the
factory to set up and register a custom manufacturer ID.
Write protection or EPROM emulation mode is activated
through the Write Memory command by writing to the
corresponding locations (PPA to PPD) in the administra-
tive data page. Once a protection is activated, it cannot
