Maybe Atmel has the smallest case but PIC 10F200 is not far behind, available in 2x3(x1) mm DFN, and that has been true for a while now. Please try to read between the marketing hype lines... A more interesting question would be, do people here build their own micro bed of nails to program these things in circuit? I did build some custom bed of nails for programming years ago when tolerances were not as low as now. -- Peter -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
