# 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.

TODO: Example solder photos.

### Side-by-side pure converter version

* You have to solder PGA44-PLCC44 socket and DIP22 x 2 headers.

* Done!
