XC6SLX45T-2FG484C与XC6SLX45T-2FG484I有什么区别

找到答案吧。
代表不同的温度范围。
一个用于商业（0-85），一个用于工业（-40-100）。



以下为原文

Just find the answer. Represent different temperature range. One for commercial (0-85), one for industry (-40-100).

大约100美元。
不用说，“C”和“I”后缀之间的区别是工作温度
范围。
“I”部分是在工业温度范围内指定的，而
“C”部件仅在商业温度范围内指定。
通常是
硅将是相同的，但测试将在不同的温度下进行
范围。
为了满足更严格的温度要求，“I”后缀部分
可能比同等的“C”部分快一个速度等级
在商用温度范围内测量时，但对于Xilinx部件，则测量它们
未按此规范进行测试，因此不能保证它符合更高的要求
“C”速度等级。
如果你在获得零件时遇到困难，你总是用“I”级零件代替“C”
等级部分，并知道它至少也会起作用。

About $100.
 
No seriously, the difference between the "C" and "I" suffix is the operating temperature
range.  The "I" parts are specified over the industrial tempurature range, while the
"C" parts are specified only over the commercial temperature range.  Usually the
silicon would be the same, but the testing would be done over a different temperature
range.  In order to meet the stricter temperature requirements, the "I" suffix part
would probably be about one speed grade faster than the equivalent "C" part
when measured over the commercial temperature range, but for Xilinx parts they
are not tested to this spec so there are no guarantees that it meets the higher
"C" speed grade.
 
If you have trouble getting parts you cn always substitute an "I" grade part for a "C"
grade part and know that it will work at least as well.
