it's not the crystal, it's probably the serial communication between the computer and the programmer
i used my pic16c84-04 with 10, 14.318, and EVEN 16 MHZ crystals and they were working fine, i would assume that pic16f84-04's would work as well with 10 or so MHZ crystals
p.s. the pic16f84a-20 can even handle speeds upto 25 MHZ
(verified by me)
:wink:
also, it is not necesssary to use exactly 4MHz...You can use even 32KHz. you can refer to application note AN582 from Microchip official website
