True, but FPGAs are harder to code for, and more expensive. I work with both platforms and find them about as easy to code on, with the Prop costing a little less but requiring external parts to do ADC/DAC.

FPGAs have gotten pretty cheap nowadays. They also aren't that difficult to program if you know Verilog.

we have made a A3P250 FPGA board, with build-in USB interface, total cost of building the board is less than $50, can do a ton of things MCU can not do. would anyone want it if we commercialize it? http://cdn.shopify.com/s/files/1/0117/1482/products/IMG_0305... The design was based on http://skywired.net/blog/projects/a3pn250-fpga-breakout-boar..., added regulator chips, got rid of the power-on-reset chips.

If you're not sure, you could start a Kickstarter. That's what it's for - products which are only viable if a certain number of people put down cash.

How does the actel toolkit compare with the xilinx toolkit?
