DESCRIPTION

The DS2502-E48 is a variant of the DS2502 1024-bit add-only memory. It differs from the standard

DS2502 in its custom ROM family code 89h, and the UniqueWare Identifier 5E7h in place of the upper

12 bits of the standard ROM serialization field. Otherwise, the electrical and logical behavior is identical

to that of the DS2502. For technical details please refer to the DS2502 data sheet.

The first 32 bytes of the DS2502-E48’s EPROM memory contain a globally unique 48-bit node address and are write-protected. The data structure follows the conventions of UniqueWare devices using Default Data Structure (Figure 1). This format is also known as ...

The four bytes at memory addresses 01h to 04h contain the UniqueWare Project ID 00001129h. The two bytes at addresses 0Bh and 0Ch are the inverted 16-bit CRC over the length byte, Project ID and node address value. The least ...
