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 Xilinx XC9500XL
family has some of the cheapest and readily-available CPLDs. This
development board from Dangerous Prototypes will help you build your
first custom logic chip using simple schematic entry, Verilog, or VHDL.
- XC9572XL CPLD with 72 macrocells
- 5volt tolerant inputs
- On-board 3.3volt power supply for core and pins
- Selectable 3.3volt or external supply for pins (1.8volt to 3.3volt)
- LEDs for output
- Push button for input
- Populated JTAG header
- Easy to program with the Bus Pirate
