Well, if you are "just" doing a LED driver, then a Spartran II is a
bit of over the head. But on the other hand, it becomes dead cheap to
do funny things with the LEDs if you feel up to it ;O)

There is nothing like LED drivers which get boored by doing nothing
and invent their own little dance while awaiting a task which is
consideres worthy of actually doing!
