FPGA Comparison. EZ1CUSB. EZ1CUSB Pro/Con. 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 Pro/Con. Pro’s One of the cheapest
E N D
EZ1CUSB Pro/Con • 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 Pro/Con • 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
EZ2USB Pro/Con • 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 Pro/Con • 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)
Conclusion • XEM3001 the best • Many pins so Parallel EEPROMs are an option • Excellent for expandability
