Read Unique ID Number (4Bh)
The Read Unique ID Number instruction accesses a factory-set read-only 64-bit number that is unique to
each S25FL016K 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
