hi
i am making aproject of smartcard {whith fun card} and i have problem in supply the card with a clock as you know the card contain(at90s8515) and and must supply with oscillator to generate the clock but the card have only one pin to provid it with the clock so any one know how to do that
i wish any one can help me if one have asolution u can mail me
thanks for your replay ,but i use a (a16f876)pic to read frome card can i take the clock frome the (xtal2)pin of it & if i use it i conect it to the card direct or make some modivy to it ???????

A high input impedance, and a low output impedance - there are many possibilities, including a single transistor, or a logic gate. But for a start, try it without and see if it works.
thanks for all friend i will try your advises and will see and by the way any one know a site have aexamples of at90s8515 microcontroler programe write with asm for project
