This application note describes a cost-optimized copy protection scheme that helps protect an FPGA against cloning. The design leverages an external secure serial EEPROM. The included reference design uses an optimized PicoBlaze™ 8-bit microcontroller. This application note provides a hardware design with associated PicoBlaze software code. The code loads a secret key into the secure EEPROM and authenticates the user system with the secure EEPROM.
