Hi, I am planning to use a Spartan 6 FPGA (XC6SLX9) in my new design. Could someone suggest a reprogrammable PROM to configure this device, like the capacity of the Flash PROM needed ?

Works fine. We just use a .BIT file in a B&K USB programmer. We actually solder the SO-8 to a small adapter board so we can plug it into a dip socket. Check the Xilinx lit to see how many config bits you need. The /45 needs around 10 mbits. For some reason I do have to erase them before I program them. I thought flash didn't need that. John

Hi, Thank you for your suggestions. I will take a look at them and get back to you if I have any more questions. Aditi.

I use their 1-mbit version on a smaller FPGA, but they have a 4 mb part, http://mouser.com/ProductDetail/Atmel/AT29LV040A-15TU/?qs=sGAEpiMZZMtI%252bQ06EiAoG1KfhKGNTAIqdwDuLxOe7u0%3d I use the so-8 package, but they have a smaller chip-scale version.

The part I'm using is the SST 25VF010A, the 4 Mbit part is the SST25VF040, they have a couple variants and package choices. These things are MUCH cheaper than some other makers, and have worked quite well in my application. I did have to write my own serial programming routine for them, but it wasn't too hard. Jon

Uncompressed, standard bitstream sizes for Spartan-6 are listed in UG380 (Table 5-5 in v2.1). Ranges anywhere from 2,724,832 for the LX4 and LX9 up to 33,761,696 for the LX150/T. Besides the other recommendations, also be aware that Spartan-6 SPI configuration supports the newer Multi-I/O Flash. This allows you to increase your configuration rate by reading back the SPI Flash in x2 or x4 modes. Take a look at the Spansion S25FL family or the Numonyx N25Q. The S25FL comes in 32, 64, or 128. Smallest package is a 5x6mm. Xilinx iMPACT supports this family as of 11.4. http://www.spansion.com/Products/Pages/MirrorBitSPIMulti_IO.aspx Only the 128 version is available in the N25Q family. Smallest package is a 6x8mm. I believe Xilinx iMPACT support is slated in 12.1. http://www.numonyx.com/en-US/MemoryProducts/NORserial/Pages/N25Q.aspx I have experimented with both families with Spartan-6, and both work well, with the added benefit of potentially configuring 4x faster.
