I think almost every FPGA is like that -- I think ones that have internal flash (like the Spartan-3AN) are still SRAM based and just have a flash chip in the package as well.
The only flash based programmable logic from Xilinx/Altera are CPLDs as far as I remember.
External SPI flash is pretty cheap even at low quantity (~$0.50 at qty 1 for 2Mbit, going down to the $0.30 range for low thousands)
- makomk 11y agoYeah, but FPGA dev boards usually have the required Flash chip integrated on the board rather than requiring you to supply your own.
- raverbashing 11y agoOf course. Because it's a dev board
- david-given 11y agoHow big is the bitstream for a device like this?
- taralx 11y agoTrue flash FPGAs do exist -- they're used when startup time is important. Microsemi has quite a few.
