'[PIC]: 16f84A 10MHz - Real speed is 2.5MHz?'

Hi everyone,

Just need to confirm, if the PIC osc freq. is 10MHz, then the instruction
runs in 2.5MHz? Which means each instruction takes 400 ns?

Thanks

Correct,

internal clocking speed is always Fclk/4.

Yup, just like the data sheet says.

Hi,

Thats true, Pic internal takt is Xtal/4.
When you need more, the AVR L version 4MHz (250ns) at 3,3V/7mA.

Yes, except for the ones that take 800ns.

Gee, it's been a long time since I saw a question answered so clearly and
succinctly by so many list members! ;-)
