SMBus Interface 5-Pin SOT-23 T/R

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.

• Unique, Factory-Lasered and Tested 64-bitRegistration Number (8-bit Family Code + 48-bitSerial Number + 8-bit CRC)
• SMBus-Compatible I²C Serial Interface
• Supports 100kHz and 400kHz CommunicationSpeeds
• 5V Tolerant Interface Pins
• Operating Range: 1.8V ±10% to 5V ±5%, -40°Cto +85°C
• 5-Pin SOT23 Package
