I was wondering if anyone knows if there is a way to battery back up the time for the PSOC 4 RTC component coming out in Creator 3.2 without backing up the whole processor? If not, what is the point of the component other than a timer that counts in days, months, etc? I am just wondering if this component in any way means I don't need my trusty old DS1307 any more.
The PSoC4 BLE goes as deep as 150nA in Hybernate mode which might be low enough for batt supply.
But the RTC -which is software only except the timer- is capable of DST, weekday calculation etc. You may still use your good old DS1307, sync the RTC at power up (and in between) and display current time and date while the PSoC is running.
