* high accuracy
* useable via I2C
* very little power consumption
* externel battery (no integrated LI-battery)
* small amount of (better no) additional parts needed (beside
* additional programmable features (alarm, interrupt etc) would be
This chip is needed to maintain date/time while the beaglebone is
without power and will have no connection to the internet while
powered up next time.
What can be recommended? With what chip one has made goot
Thank you very much for advance for any help!
