EZ1CUSB
EZ1CUSB P RO /C ON Pro’s Don’t have to reprogram at boot Built in USB FPGA interface Has the most I/O Pins Con’s Most expensive Never programmed an Altera before Soldering would be difficult
EZ1KUSB
EZ1KUSB P RO /C ON Pro’s One of the cheapest Already built in USB FPGA interface Con’s Least amount of I/O Pins Never programmed an Altera before Must be reprogrammed at every boot Hard to solder
EZ2SUSB
EZ2USB P RO /C ON Pro’s One of the cheapest Already built in USB FPGA interface Familiar with Xilinx products Con’s Least amount of I/O Pins Must be reprogrammed at every boot Hard to solder
XEM3001
XEM3001 P RO /C ON Pro’s One of the cheapest Don’t have to be reprogrammed at start Built in USB FPGA interface High level of support and tools (SDK’s and API’s) Good number of I/O Pins Familiar with Xilinx Spartan 3 FPGA’s Con’s Hard to solder (easier than the other three)
C ONCLUSION XEM3001 the best Many pins so Parallel EEPROMs are an option Excellent for expandability
