CY7C68013 EPM1270 CPLD USB 2.0 development board
« on: September 25, 2016, 03:16:37 am »
My computer crashed, and I lost the schematics  and doc's of this development board, Do anybody have this information to share.

I need to make a usb FPGA device and this board in my lab stock it's perfect for my need, but without info is a little hard

I might still have the same board around, bought from ebay and never used since I prefer Xilinx
I say *might* because I am not sure if I still have the documentation with me, I need to check  :-//

p.s. on ebay you can find Cypress-USB breakouts (without fpga) for 10 USD
I am tempted to buy one of those and to interface it with my Papilio/Pro (Spartan6)

The board is still advertised by several vendors on AliExpress. One also sells bare boards and claims to supply the schematic PDF, maybe try contacting them?

The bare board images show footprints for decoupling caps on the underside.

The board have 2 sides a lot of decouple caps on another side, also board does not clock miraculous the clock in on another side also

Thank you for your reply

I asked for a schematics and doc's, And you help me telling that if i follow all those minuscules traces  on the board one by one, and write down to a papper, I can make my own  schematic. Huau that's the best advice i have in my live

 :phew:

Honestly, the wiring on that board appears pretty straightforward to follow.  It will be a good example for me to cite if someone foolishly tries to argue with my rant against black solder mask.

The only documentation you really need is the data sheets for the relevant parts.  You'll need those even if you do find a schematic for the board itself.

Where in the datashets parts I will find VHL demos specific for this board ?

I basically asked if someone  as the same board and would like to share this files, only one reply is related to the original posts and can be considered useful, all others are useless that don't help in anyway. I hope the next post will not be to please connect power on the circuit. Think before write

If you dont' have any luck with a schem/files, then I would trace it out by hand.

The three headers already have pin numbers on them (I'm assuming they are all FPGA pin numbers) so you would jsut have to trace the cypress chip connections, and the SRAm (is it SRAM? I jsut assumed it was).  Whilst it seems daunting, you'll be surprised how quickly it can be done, with a cup of coffee, a continuity tester and either pen and paper, or an Excel spreadsheet.

I recent had to do it for an FPGA board that had footprints for SRAM, but the docs were long gone.  I seem to remember it took me half way through an episode of the x-files.

@ebclr
we are lucky, I accessed my laptop (sorry I was 250 Km away from where I live, now I am back)
and I found a backup of the whole DVD which was included with the board when I bought it

good news: we have it
bad news1: it's mostly written in chinese and you need to sort things out(1)
bad news2: it's 4Gbyte


(1) even folder's labels are written in chinese :palm: :palm: :palm: :palm:
also there is a lot of confusion about the content
things come with no order  :palm: :palm: :palm: :palm:
years ago I had sorted things out and focused on essential things
(schematic, constraints, examples, doc written in English, etc)
but then I deleted the folder since I don't use Altera  :-//


anyhow, here we go  :-+

p.s.
examples are all written in Verilog
and there are whole projects for Quartus2

p.s.2
it seems you can't directly access pdf files
Acrobat pdf-reader on both Windows XP and Linux claims errors due to the filename
which contains chinese characters (unicode?)
but you can access those files once copied to the hard drive and property renamed

Thank's a lot man

Normally those chinese CD's have a lot of stuff

basically i need only the demos files and projects ( VHDL or HDL )and the schematics, all other stuff is unnecessary if the size isn't so big after compress i can give you one ftp to upload or any other method you want
