LatticeXP2 configuration encryption and security usage guide

Unlike a volatile FPGA, which requires an external boot-prom to store configuration data, the LatticeXP2 devices are non-volatile and have on-chip configuration Flash. Once programmed (either by JTAG or SPI port), this data is a part of the FPGA device and can be used to self-download the SRAM portion without requiring any additional external boot prom. Hence, it is inherently more secure than volatile FPGAs. Like the LatticeECP2/M, the LatticeXP2 family also offers the 128bit Advanced Encryption Standard (AES) to protect the externally stored programming file. The user has total control over the 128bit key and no special voltages are required to maintain the key within the FPGA.
