有Spartan 3系列的路线图吗？

嗨，
如果有Spartan 3系列的路线图或产品生命周期文档，有人可以告诉我吗？
我们目前在现有产品中使用Spartan 3A器件（XC3S50A-4VQG100C）。
我现在处于新设计的早期阶段，改进了原始设计，并在研究市场上是否有更便宜/更好的Xilinx器件后，我注意到Spartan 6系列现在作为“低端”产品和Spartan推向市场
3不再出现在网站上作为产品系列（除汽车级别外）。
这让我有点担心Spartan 3没有在商业上销售，我不确定这是否应该用于新设计？
Spartan 6系列QFP封装中最小的器件是XC6SLX4;
然而，当我比较定价时，它的价格是位于相同范围内的Spartan 3设备的两倍（我知道Spartan 6是一款优质设备），因此它不是等价的替代品
如果有人对此有任何建议，将不胜感激
在此先感谢LeeA Smith

Hi,

Can anybody advise me if there is a roadmap or product life document for the Spartan 3 range ?

We currently use a Spartan 3A device (XC3S50A-4VQG100C) in an existing product. I am now in the early stages of a new design improving on the original design and after researching into whether there are any cheaper / better Xilinx devices on the market I've noticed that the Spartan 6 range is now marketed as the 'Low End' offering and Spartan 3 no longer appears on the website as a product range (Apart from the automotive grade). This concerns me a little that the Spartan 3 is not being commercially marketed and I'm unsure if this should be used for new designs ?

The smallest device in a QFP package from the Spartan 6 range is the XC6SLX4; however when I compare pricing this is twice the price as the Spartan 3 device which is positioned in the same range (I understand the Spartan 6 is a superior device), therefore it's not an equivalent cost alternative

If anybody has any advice on this it would be appreciated

Thanks in advance Lee A Smith
