In a couple of cases where I designed in a Microchip part, a Xicor part would not function in the same socket with the same software. At the time I was in crunch mode and didn't have the time to figure out why. A quick scan of the data books did not point out any obvious differences. I had a chat with a Microchip technical person on this and he agreed there was a difference but couldn't remember what it was. Perhaps someone has persued this in more detail and could post his/her findings. -- Bob Fehrenbach Wauwatosa, WI bfehrenb@execpc.com
