PGA44 to DIP44 socket PCB project

What is this?

• This is very simple electric circuit diagram on EAGLE CAD.
• This is my first trial for learn how to use EAGLE CAD.
• I made for prototyping CPLD device (Xilinx XC95 series) on the breadboards.

Artworks

• Xilinx XC9536/XC9572 version

• Side-by-side pure converter version

How to use

Xilinx XC9536/XC9572 version

TODO: More improving...

• You have to solder PGA44-PLCC44 socket and DIP22 x 2 headers.
• If your usage is side by side mapped pin conversion, you have to no additional works.
• If your usage is Xilinx XC95 series, add jumper pin header to head of board and solder x2 path-capacitors (ex: 0.1uF) onto SMD jumpers bottom of center board.
  • SMD jumpers shorts circuit between 21-41(VCCINT), 23-10-31(GND).
  • If jumper pin header closed, it shorts circuit between VCCINT and VCCIO. It means commonly voltage usage.

Side-by-side pure converter version

• You have to solder PGA44-PLCC44 socket and DIP22 x 2 headers.
• Done!
