[sdiy] Divide by 10^6?

[Needham, Alan]

A tiny microcontroller would eat this job - single chip solution.
Use the 20MHz as the micro's clock and a simple program could even
supply a couple of LED flash rates (or 4 LEDs with quadrature drives?).

Hello everyone,

I have a question for the logic & digital folk: is there a
low-component-count, off-the-shelf way to divide down from 20MHz to
20Hz?
I'm trying to add a clock rate LED to the Sound of Shadows delay module
prototype I'm working on. A cascade of six 74*90 ICs works fine, but
that's
a lot of board space just to blink an LED.

Best regards,
