Description
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.

Key Features   Applications/Uses
  • Unique, Factory-Lasered and Tested 64-bit Registration Number (8-bit Family Code + 48-bit Serial Number + 8-bit CRC)
  • SMBus-Compatible I²C Serial Interface
  • Supports 100kHz and 400kHz Communication Speeds
  • 5V Tolerant Interface Pins
  • Operating Range: 1.8V ±10% to 5V ±5%, -40°C to +85°C
  • 5-Pin SOT23 Package

 
  • Accessory and Peripheral Identification
  • Equipment Registration and License Management
