Anyone have a source and part number for this 7805 replacement?
Definetely the best solution.

On a similar topic, when are the HV parts available?

Craig, if I find out anything I'll let you know.  Ever since the seminar
in Calgary, I've been on Pioneer's case about getting some samples.

Craig,

I wrote the other day that I'd keep you apprised of my attempts to
locate an HV part mentioned at the MChip seminar.  I just heard from
Gail at Pioneer that I've got a couple of 16HV540 samples on the way.
She also handles Edmonton, so give her a call.

I got lost.  What exactly are the HV parts?

AFAIK, there's only one part - the 16HV540.  All the information I have
on it I got at the seminar:

Enhanced PIC16C54 with
- on-chip regulator for operation up to 14V
- 4 stack levels
- wake-up on pin change
- 8 high voltage I/O, 4 regulated I/O
- Brown-out
- current consumption less than 3uA at 14V in sleep.

I've just spent 20 minutes searching their web site for proper specs,
but came up dry.  I emailed the MChip webmaster for any clues but a
response might take a while.  If anyone knows where the data sheet is
hiding, I'd love to know.
