Why not use an external oscillator? Either a ready made one or for the
lowest power consumption build your own. A 32KHz oscillator coule probably
be built to take less than 10uA (32KHz is a common frequency used in
I have used a Motorola HC908GP32 originally with a 32KHz crstal as
recommended but then approved a second crystal vendor and often had
oscillator start up problems - so I changed to a separate oscillator and
htere have been no more problems.
Seiko and a few other vendors also do similar. Note that the Epson part has
a 2uA current consumption.
