    Ioannis,

    I am interfacing with PYD1998 (digital output pyrodetector) and the communication requires a pause min.200nS.

    I am using 12F675 (intosc) and the min. delay is 1uS.

    1uS does not give precise results.
    Since, a delay faster then 1uS at 4Mhz is not possible, now I have no choice but use a chip with 8Mhz intosc ( based on Alain's calculation I can get 500nS).

    This time, the unit cost will be on table.

    Apparently, you can run a 16F628A at 4Ghz.
    A 1ns delay would just be a NOP.
    Anyone can show me a practical application of this?


    P.S. - Welcome back Skimask! Howzit?
