Russell,

Not quite meeting your criteria, but take a look at the PIC16LF818/819, not
0.9V unfortunately, VDD is 2.0V min.  I am playing with some samples at the
moment, and it's certainly frugal on power compared to it's older siblings.

The part is in production, supported by MPLAB6.1, ICD2 and Picstart+,
perhaps others tools too.

2 cells, maybe?
