DS2502-E48 - 48-Bit Node Address

General 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.

Key Features

  • Factory programmed 48-bit node address chip with 768 bits user-programmable.
