I ordered some *16F84A* microchips from a website, but instead they sent me *16LF84A* microchips. Are there any significant differences between the two? I looked in the datasheet, but the only difference I could find is the difference in supply voltage. Does it make much difference? I don't really want to go through the hassle of returning them. - Xiao Xu -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
