Cyclone IV E EP5CE55F23C8N Reference schematic design

Hi

My design need use EP4CE55F23C8N chip, but I can't find an reference hardware design of it.

So,

It's a little difficult to start this hardware design, this chip have so many Pins...

I found some supporting documentation, but, if I can get an reference design, it is very helpful.

Such as: an schematic other people used. 

My main concern is the use of pins, by referring to other people's pin assignments and combining my own design, I can easily confirm that my design is correct.

Do we have such files.

And, 

It is difficult for me to find a local agent to get intel FPGA support in China. There is no direct person to connect with. So, I have to come here ask for help. Does Intel have this consideration.

Please provide some help, which will be very helpful.

Thank you.

Hi there

 

We don't categorize the design into specific package ordering. You can search for example design for Cyclone IV below:

https://fpgacloud.intel.com/devstore/platform/?acds_version=any&family=cyclone-iv

 

For pin assignment, there are 2 main references you can check:

1. Pinout file (you can check the IO function per pin):

https://www.intel.com/content/www/us/en/programmable/support/literature/lit-dp.html

2. Pin Connection Guideline (you can check on description of each IO function)

https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/dp/cyclone-iv/pcg-01008.pdf

 

Let me know if you have any question.

 

Thanks.
