Are you fixed on using a pic? The msp430 series from ti are very low power,
and have an optional internal oscillator. It also has several versatile timers that can

Many PICs (or almost any other micro) can meet all your specs with a
32KHz watch crystal which runs continuously and you use a timer to
interrupt and wake up the CPU at the pre-set time interval.

(brownout) and WDT (watchdog) that should be it on the current
requirements without sleeping. Sleeping and using a watch crystal
connected to T1OSC could save you maybe 50% off that on the power.
Probably not really worth the extra effort, unless you want to be able
to wake up and crank the CPU speed up to 8MHz.
A lantern battery won't be necessary, a couple of AA batteries should
easily last for years even running continuously.

Any nanowatt PIC should do.
Use a watch crystal to run it.
A PIC 12F683 uses something like 18uA typical running at 32kHz on 3V and
only 9uA typical at 2V. As long as you can live without the BOD
(brownout) and WDT (watchdog) that should be it on the current
requirements without sleeping. Sleeping and using a watch crystal

no worries. I should have given a summary though: its pretty darned

You probably don't need a nanoWatt device either, do the power

might find that will be OK for your requirements too.
BTW, with a clock speed this low you will need to choose the internal

shows that you have no real shortage of choice.

I did some research recently and found that for the quantity your looking at
maybe the GPS mouse variety with serial interface (TTL vs RS-232).
In OZ landed for about $80.00 (US$35 + AU$30.00 freight per unit). Nice
feature is that the ones I got had magnetic base plus inbuilt antenna (one
had an active antenna). Negotiate freight as DHL are bloody expensive,
better off using post.
I found the chaps overseas very helpful and the products very good in terms
of performance and quality.
Idea of prices -
"Gere Tan(www.iternet.com.tw)" <gere@iternet.com.tw>
PS-1200 GPS mouse
Sample -- USD 42
100 PCS --USD 32
Remarks:
----------------------------------------------------
1. Term: FOB Taiwan.
2. Payment: T/T in advance.
3. Lead time: 3 ~4 weeks after receive T/T payment
Please don't hesitate to contact me for any further question.
HI-204E was phased out and belows are the rest of items for
sample/100 pcs
FOB Taiwan prices:
HI-204S US$ 34.00/US$ 30.00
HI-204III US$ 37.00/US$ 33.00
