Configuration
XA Spartan-3A FPGAs are programmed by loading configuration data into robust, reprogrammable, static CMOS
configuration latches (CCLs) that collectively control all functional elements and routing resources. The FPGA’s
configuration data is stored externally in a SPI serial Flash or some other non-volatile medium, either on or off the board.
After applying power, the configuration data is written to the FPGA using any of five different modes:
Serial Peripheral Interface (SPI) from an industry-standard SPI serial Flash
Byte Peripheral Interface (BPI) Up from an industry-standard x8 or x8/x16 parallel NOR Flash
Slave Serial, typically downloaded from a processor
Slave Parallel, typically downloaded from a processor
Boundary Scan (JTAG), typically downloaded from a processor or system tester
Additionally, each XA Spartan-3A FPGA contains a unique, factory-programmed Device DNA identifier useful for tracking
purposes, anti-cloning designs, or IP protection.
