推荐用于Spartan-6的SPI Flash

您需要的大小取决于您在比特流之外需要存储的内容。
我摔倒
你正在做的是配置FPGA（单比特流 - 没有备份）然后你可以使用
UG380第69页表5-5中的尺寸作为最低要求。
例如
如果您需要配置的最大设备是S6LX45T，您将拥有11,875,232位
所以一个16 Mb的闪存可以做到这一点。
但是，如果您将拥有嵌入式处理器，
并且您的代码不适合Block RAM，或者您需要存储其他辅助数据
闪存，那么你需要添加这些要求。
影响将支持编程
M25Pxxx器件最高可达128 Mbits，无论所连FPGA的大小如何。

以下为原文

The size you need depends on what you need to store in addition to the bitstream.  If all
you are doing is configuring the FPGA (single bitstream - no backup) then you can use
the size from table 5-5 on page 69 of UG380 as a minimum requirement.  For example
if the largest device you need to configure is a S6LX45T you will have 11,875,232 bits
so a 16 Mb flash would do the trick.  However if you will have an embedded processor,
and your code does not fit in block RAM, or if you need other auxillliary data stored in
the flash, then you need to add these requirements.  Impact will support programming
of M25Pxxx devices up to 128 Mbits regardless of the size of the FPGA attached.

我自己需要。
我花了几分钟才找到它：

虽然几乎任何SPI闪存都可以配置S6，但最早的
采用者正在使用Numonyx M25Pxx系列，因为它是
第一部分由Impact支持，使用直接或间接编程。
Atmel Dataflash部件现在也支持间接编程。
您应该确保您选择的任何设备都受Impact支持
如果您打算在系统中编程该部件。

以下为原文

While almost any SPI flash will work to configure the S6, most early
adopters are using the Numonyx M25Pxx series because it was the
first part supported by Impact using either direct or indirect programming.
 
Atmel Dataflash parts are also now supported for indirect programming.
 
You should make sure any device you pick is supported by Impact
if you intend to program the part in system.

您好Leon，感谢您的链接和帮助。
但是，我找不到一个特定的文档，它向我展示了我为XC6LSX4​​5-xxxx使用的特定Numonyx SPI闪存（或其他供应商）。谢谢Daniel

Hello Leon,
Thanks for the link and for the help.  However, I could not find a specific document where it showed me what specific Numonyx SPI flash (or other vendor) I shuld use for the XC6LSX45-xxxx.
Thanks,
Daniel
