I need to determine worst-case for the power supply (batteries and solar charger). Have the ancillary chips figured out, but need to get a grip on the SX itself.[/2] 1. Does the table below tell me what the max power consumption *could* be on the '48? --- specifically the "total power dissipation" entry below? (Including pulling the max current from the SX pins - within the pins' and chips' tolerences of course). Y/N? 2. Would this reflect full speed (say 75mHz) in a tight loop? Y/N? 3. What would you search for here in the forums to get some info on batteries and solar chargers ? --- I imagine this is a pretty common discussion.
