    Is there any difference between NE555N and NE555P integrated circuits? The pinout is the same?

    In general the beginning letters refer to the temperature range that the chip has been designed for, while the ending letters refer to the package the chip comes in. Some manufacturers use 'N' and others use 'P' to refer to the PDIP package or Plastic Dual In-line Package. So it is likely that the NE555N and NE555P come from different manufacturers.

    Ok.Thank you.
    I have just created my first flashing LEDs.

    The NE555P are precision timing circuits capable of producing accurate time delays or oscillation. The threshold and trigger levels normally are two-thirds. but both numbers of NE555P Pinout and NE555N Pinout are 8. In the time-delay or monostable mode of operation, the timed interval is controlled by a single external resistor and capacitor network. In the a stable mode of operation, the frequency and duty cycle can be controlled independently with two external resistors and a single external capacitor.
