Re: [Usbpicprog-technical] Programming PIC16F84

[Diego H. <die...@di...>]

Hi Anthony,

16F84A is available in both 4 MHz and 20 MHz versions (not 10 MHz). Just in
case you were looking for a 10MHz version which to my knowledge does not
exist.

Also, the 20 MHz version can be found on ebay (look for "PIC16F84A-20").
While not cheap, it's affordable for a single unit (less than 7€ including
P&P).

Cheers!
