How to read and Understand the xilinx part numbers and abbreviations, model numbers

Jump to solution

Hi,

    I am new to this site and also to FPGA. I would like to buy xilinx Virtex board and it reads as Virtex 5 LX FPGA FF 1760.

 

What is the following?

Virtex

LX

FF 1760

XC5

VLX110

 

Kind enough to help me how to read and understand naming specifications.

Gabor answered your query well. According to that I am giving one example description for more clarity

 

 

An example of an ordering code for a Xilinx FPGA is XC4VLX60-10FFG668C. The

ordering code stands for:

XC4VLX – Family (Virtex®-4 LX)

60 – Number of system gates or logic cells (60,000 logic cells)

-10 – Speed grade (-10 speed)

FFG – Package type (Pb-free flip-chip BGA)

668 – number of pins (668 pins)

C – Temperature grade (Commercial)

Perhaps reading the Virtex 5 datasheet could help?

 

Link to datasheet here -> DS100

Hi,

 

An example of an ordering code for a Xilinx FPGA is XC4VLX60-10FFG668CS2. The
ordering code stands for:
XC4VLX – Family (Virtex-4 LX)
60 – Number of system gates or logic cells (60,000 logic cells)
-10 – Speed grade (-10 speed)
FFG – Package type (Pb-free flip-chip BGA)
668 – number of pins (668 pins)
C – Temperature grade (Commercial)
S2 – Step 2

 

You can check the packaging guide for the part/package marking.

 

Also to determine valid ordering combinations for a given device, consult the device data sheet as posted by other user in the earlier post.

 

Thanks,

Deepika.

Thanks,
Deepika.

I believe the XC is "Xilinx Commercial" - however this particular "C" relates to application, not temperature range.

 

There is also XA ("Xilinx Automotive")

 

Virtex is just a marketing name for the high-end chip series.  Spartan was the low-cost (bare bones?) series.  Artix is the new low power low cost (perhaps intended to sound like Arctic?) series.  Kintex is the new middle-class series.  I think the new Xilinx naming conventions are intended to sound a bit more Altera-like, something like the "New Coke" tasted more like Pepsi.

 

For some reason, the Name and Series Number are swapped in the part number, so Virtex 5 becomes 5V, Spartan 6 becomes 6S, etc.

 

Within a family there are devices optimized for different applications like

LX - General Logic, No transceivers

LXT - General Logic with Transceivers

FX - Embedded hard processor

 

The numeric part of the device number has changed from family to family, but most newer families use the approximate number of "logic cells" in thousands.  So in your case the 110 means about 110 thousand logic cells, where a logic cell is not directly related to an internal structure but represents a marketing equivalent of some theoretical cell that contained a 4-input LUT and a flip-flop.  You need the data sheets to find actual LUT size and count.

 

At the end of the part number is the speed grade, package, and temperature grade.  For Xilinx parts, higher speed grade is faster (-3 is faster than -2).

 

FF1760 indicates a flip-chip BGA, with 1760 balls.  You need to find the package drawing to get the ball spacing, but for most "FF" packages this would be 1.0mm
