I have been using the 813F1 for a few months now, and have found it a very neat solution to my problem. I found the devices very easy to get going, apart from sharing the JTAG port with GP I/O and managed to ruin a device, still it was a free sample.

I have been happy with the support provided so far, and especially with the samples service. The S/W is easy to use, although to use the 8xx family you will have to buy the S/W, the 9xx is free!. I have the 8xx compatiable S/w and the Waferscale flash link cable, it's only $99 so it's not exactly expensive.

My app has a DS80C320 with a PSD813F1 driving a IDE HDD with only a couple of latches/and buffers to actually implement the interface, all the logic / memory decoding's in the PSD.
