MSP430G2210: RTC Application and current consumption

kukdam

Part Number: MSP430G2210

Tool/software:

We are utilizing the MSP430G2210 in our project and are interested in implementing an RTC. Could you provide any reference code for this, and let us know the current consumption for the RTC alone? Any information on this would be greatly appreciated.

This would seem a poor choice for that application. Normally you would use a 32KHz crystal with a LFXT and spend almost all time in LPM3. (~0.5uA on this part). But this device doesn't have an LFXT. You could do it using the internal low power oscillator, but accuracy would be a lot worse.
