DS28CM00

DS28CM00 I²C/SMBus Silicon Serial Number www.maxim-ic.com GENERAL 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. FEATURES ƒ ƒ ƒ ƒ ƒ ƒ 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 APPLICATIONS Printed Circuit Board Unique Serialization Accessory and Peripheral Identification Equipment Registration and License Management Network Node Identification ORDERING INFORMATION PART DS28CM00R-A00+T TEMP RANGE -40°C to +85°C PIN-PACKAGE SOT23-5 Tape-and-Reel +Denotes lead-free package. www.DataSheet4U.com TYPICAL OPERATING CIRCUIT VCC RP VCC SDA SCL RP PIN CONFIGURATION SCL GND SDA 1 2 3 4 NC 5 VCC µC GND VCC SDA SCL DS28CM00 GND SOT23 Note: Some revisions of this device may incorporate deviations from published specifications known as errata.
