Components I Usually Use (I): DS28CM00 – I2C Serial Number

The first one is the DS28CM00 I2C serial number. This device is an electronic registration number that gives you an unique 64-bit serial number over I2C or SMBUS interface. This 64-bit serial number is  factory lasered, so there aren’t  two devices with the same number.

I use this component in a railway application, to identify the PCB’s mounted in the system. The pinout and the typical connection of this device is shown here:
