    Don't know, but it's very different from the classic Signetics 555, and if
    I'd been them I would not have called it 555, especially since it's in the
    same package.

    I think (without looking up all the details) that not only is this not a 555
    derivative, it is actually a programmed PIC microcontroller (or maybe AVR).
    The frequency accuracy, power pins, and general frequency range are what I'd
    expect...

    So to answer your question, I could make one myself in a couple of hours or
    less. A single-frequency version, much quicker than that.

    Still, it's a handy thing to have available for people who don't want to
    program a microcontroller for every simple project.

    I should add...

    When I say I could make one, that doesn't mean you shouldn't buy theirs. If
    I knew how to use a metal lathe (which I don't), I'd be able to make my own
    nuts and bolts. But that doesn't mean I'd never buy them at the hardware
    store!

    I rather like the Hightechips approach to packaging preprogrammed
    microcontrollers as solutions to analog electronics problems.

    "Our approach towards product development allows us to introduce new

    this without affecting the quality of our end product."

    Their secret being writing a bit of code and burning it into 35 cent
    Microchip PIC12F50x.

    Bit dishonest and pointless of them to pretend they are not doing this.
