yes, it will work, with a corresspondingly higher pitch. i have
successfully used a 3.58 MHz tv colorburst crystal with this chip.
a 4.00 MHz crystal worked fine too, but was a little too high
pitched. the particular sp0256 i was experimenting with ran with
a 6.00 Mhz crystal, though i doubt if they all would.
