Hi Ian,
thanks for your reports. I'm planning on developing an ultra-low power PCB and your findings will help me,although I'll choose the LPC800 family.
I already built a Geiger counter (without uC) running at <200uA@5V and from that project I know that such low power consumption requires
completely new approaches and awareness of problems.
I built an (Linux) ISP programmer for the LPC's and there I have to struggle with scarce documentation or even false documentation and I get angry at some times. But hey, the people at NXP are humans, too. If your application is off the mainstream, you don't get the attention you'd wish to get. But that's what forums like this are all about - one user sharing experience with the other. To step in, when NXP has not the resources to care about your problem too much at the moment.
Of course, from your point of view it's unsatisfactory to get no replies at all. But I'm sure your input will even improve documentation of the microcontrollers even if no one replied explicitely.
We rarely report, how easy it was to create a successful circuit. We complain in this forum most of the time.
