The Spartan
an integrated SHA-1 engine. As shown in
Maxim 1-Wire interface, which as the name implies, cleverly uses a single wire for power
and serial communication.
The DS2432 EEPROM offers one of many possible means to copy-protect the FPGA
configuration bitstream, making cloning difficult. Xilinx application note XAPP780, listed
