DS2502P-E48+

The DS2502P-E48+ is a 48-bit Node Address Chip with built-in multidrop controller ensures compatibility with other 1-Wire® products. 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 behaviour is identical to that of the DS2502. 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. This format is also known as UDP (universal data packet) and is commonly used in 1-Wire® APIs. Therefore, if using one of those APIs one can call a high level function to read and verify the inverted CRC16.
