i am preparing project where system has to do periodic analog measurement and send it to external circuit via serial and the whole thing is battery powered, so consumption is important. The design is pretty simple, but i am deciding between Atmega 3209 and SAM L10. The L10 is considered one of best low power cortexs, but when comparing power consumption between them, the 3209 comes out as a winner, simply to the fact that it can run at 32.768 kHz. The measurement is done and sent out only once per minute, so the speed is not an issue. Or did i miss something that would make SAML10 better?
SAML10 datasheet(power on page 1130+):
Atmega3209 datasheet(power on page 12+):
Thanks in advance for any input form your side.
