Device Serial Number

The device serial number (DSN) is a 128-bit unique device ID. It comprises of two parts—the factory serial number (FSN) and the serial number modifier (SNM). The first part of the device serial number is the 64-bit FSN that uniquely identifies a device. The DSN is zeroized if “unrecoverable” zeroization action is performed on the device. For more information about zeroization, see Zeroization.

The device serial number can be read by the user logic using a system service call. For more information, see PolarFire FPGA and PolarFire SoC FPGA System Services User Guide.
