We made a mistake. This batch of XC9572XL CPLD development boards has one IO pin (P7) tied to the power supply (VCC/3.3volts). If you don't use pin 7 in your design the board is perfectly usable. For $8 you can start learning about programmable logic, check out our tutorials. Need pin 7? Check out the XC9572XL v1b board, with the pin fix. For full specifications please see the XC9572XL v1b board.ResourceHardware designCPLD programming and development tutorials (lots and lots of info)XC9572XL datasheetFree Xilinx ISE development softwareXC9500XL vs CoolRunner-IIIf you encounter any problems when using this product, here is the forum from which you can get the technical support.
