DS2502 Overview
The DS2502 1K bit Add Only Memory identifies and stores relevant information about the product to which it is associated. This lot or product specific information can be accessed with minimal interface, for example a single port pin of a microcontroller. The DS2502 consists of a factory lasered registration number that includes a unique 48 bit serial number, an 8 bit CRC, and an 8 bit Family Code (09h) plus 1K bit...
