SILICON LABEL DESCRIPTION  
The DS2433 4K-bit 1-Wire EEPROM 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 DS2433 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 (23h) plus  
4096 bits of user-programmable EEPROM. The power to read and write the DS2433 is derived entirely
