It certainly isn't; it is highly likely to use a 32768 hertz*

Now, can anyone explain why that particular value ?

No, it's not the TV color burst

And for bonus points, name the chip number which all
Southbridges emulate in silicon. The original clock
chip is ancient.

I'm
trying to think of one where the abbreviation/symbol _isn't_, but the
only one I can think of is gram[me] [symbol g], and I don't think that
one's named after anyone.)

If you pronounce her name the way my wife does, perhaps it's named
after Martha Graham.

My bad - I should have read your reply before posting mine.

Yours was fine--different from mine.

Well, it's 2^14, i. e. easily dividable down to 1.

Something like 7104?

Chuck Berry was once asked what he thought of Elvis Presley and he said, "He
got what he wanted, but he lost what he had." [Quoted by Anne Widdicombe, in
Radio Times 8-14 October 2011.]

Well, it's 2^14, i. e. easily dividable down to 1.

And it is divided down by a ripple divider, to save power.

It's a Motorola part and the part number is a lot
longer than that.

Sure, you could start with a ripple divider from the
4000 era, but then you'd have no way to count hours
minutes seconds and so on. Or set an "alarm" register.

This site doesn't allow direct linking, so you have to
click a few things to get the actual PDF. The PDF is actually
a scan of a printed databook, as the part predates the
existence of PDF. And in this form, this chip is a
power pig - if you ran it off a CR2032, it would not
last three years.
