Any suggestions on a low-power programmable timer that does something like the following (to wake up a microcontroller)?:
Shortest delay I need is about 10ms. Highest delay I would like is a few hundred ms, but I could get by with less. Precision I would like is 100 PPM (10us). Operates on 3V battery, and is mostly immune to voltage variations of 20% or so. It would also be nice if current was well less than 100uA.
...or am I asking for way too much? Any comments or suggestions are appreciated.
