I had looked at that chip sometime back to experiment with USB, but reali= zed=20 I'd have a prob w/o flash. I could develop and simulate on the PC, but w= hat=20 if I had to adjust the code and re-program? Seemed like having to UV-era= se=20 everytime would be a major hassle. BTW, would a UV light for photo-PCB exposure work for erasing these chips= ? Or is there some minimum power-level needed? When will there be a nice USB chip with flash programmability? Cheers, -Neil.
