Connecting Spansion SPI serial flash to configure Altera FPGAs

Posted: 11 Mar 2009 ?? ?Print Version ?Bookmark and Share

Keywords:SPI flash? FPGA configure? flash serial?

Altera FPGAs are PLDs used for basic logic functions, chip-to-chip connectivity, signal processing and embedded processing. These devices are programmed and configured using an array of SRAM cells that need to be re-programmed on every power-up. Several different methods of configuring FPGAs are normally used. They include programming by a microprocessor, JTAG port or directly by a serial PROM or flash.

Spansion's SPI flash can be easily connected to Altera FPGAs to configure the FPGA at power-up. The SPI configuration mode is supported for Altera Cyclone, Cyclone II, Cyclone III, Stratix II, Stratix II GX, Stratix III and Arria GX families.
