10.2.26 Read Unique ID Number(1)
The Read Unique ID Number instruction accesses a factory-set read-only 64-bit number that is unique
to each W25Q80, W25Q16 or W25Q64 device. The ID number can be used in conjunction with user
software methods to help prevent copying or cloning of a system. The Read Unique ID instruction is
initiated by driving the /CS pin low and shifting the instruction code “4Bh” followed by a four bytes of
dummy clocks. After which, the 64-bit ID is shifted out on the falling edge of CLK as shown in figure 27.
