DS28CM00R-A00+T Package Type, Maxim Integrated DS28CM00R-A00+T 5-Pin Processor Supervisor SOT-23

I²C/SMBus Silicon Serial Number/
Unique 64-bit factory lasered in each part. Perfect low-cost solution for embedded applications requiring an electronic serial number.The DS28CM00 is a low-cost, electronic registration number to provide an absolutely unique identity that can be determined with the industry standard I²C and SMBus™ interface. The registration number is a factory-lasered, 64-bit ROM that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit family code (70h). In SMBus mode, the DS28CM00 resets its communication interface if it detects a bus fault condition.
