Ever get stuck choosing the right logic chip combination or voltage level translator? Give up the hunt and create your own custom logic chip. CPLDs can give you the logic you need, with the pinout you want, while saving board space and board revisions.
The CoolRunner-II XC2C CPLD has two separate banks of pins that can operate at different voltages, internal pull-up resistors, and pin keepers. This development board from Dangerous Prototypes will help you build your first custom logic chip using simple schematic entry, Verilog, or VHDL.
