Clock Chip search

I am looking for a clock chip similar to an alarm clock chip with
several events you can select.

Thanks. I looked through these and the closest I can seem to get is a
"dual" alarm chip. I was really hoping I could find something off the
shelf with 3 or 4 events and separate alarm output pins for each. I am
trying to avoid cobbling up a processor and RTC for this if it already
exists.

There used to be some really neat VLSI's for clock circuits, but these days
a PIC or similar processor is simple, dirt cheap and scarcely cobbled
together.

Cheers.

Hello Ken,

There used to be some really neat VLSI's for clock circuits, but these days
a PIC or similar processor is simple, dirt cheap and scarcely cobbled
together.

Or use a MSP430 plus a watch crystal. It can run on a few uA, keep time
and handle all kinds of events.
