Hi Omer, You might want to check Microchip's 'webinar' on nanoWatt devices: NanoWattApr08.zip It's around 6 megabytes to download and extracts to a Windows Media Audio/Visual file -- it might just help you make your decision. As always, weigh in the errata notes on any processor you might switch to -- it's all about risk mitigation. Good luck.
