The DS28CM00R-A00+U is a low-cost electronic registration number IC from Analog Devices, designed to provide a unique identity using the industry-standard I²C and SMBus interfaces. It features a factory-lasered 64-bit ROM that includes a unique 48-bit serial number, an 8-bit CRC, and an 8-bit family code.
This device supports both 100kHz and 400kHz communication speeds and has 5V tolerant interface pins. The operating voltage range is from 1.8V ±10% to 5V ±5%, with an operating temperature range of -40°C to +85°C. The IC is housed in a compact 5-pin SOT23 package, suitable for surface mounting.
Applications for the DS28CM00R-A00+U include Printed Circuit Board unique serialization, accessory and peripheral identification, equipment registration and license management, and network node identification. In SMBus mode, it can reset its communication interface if a bus fault condition is detected.
