MSP430FR2512: On-chip 32-kHz RC oscillator (REFO) function of MSP430FR2512

Part Number: MSP430FR2512

Hi Sir,

We are continuing our smart doorbell project using the MSP430FR2512 and I was wondering if you could clarify some details.

We are using only one touch key for our project, and from the datasheet we know that MSP430FR2512 support on-chip 32-kHz RC oscillator (REFO) function. Due to the limited size of the PCB board, there is not much space to added an external 32.768KHz crystal oscillator. So we are wondering if the REFO can replce the external crystal oscillator.

 

Thanks,

Best Regards
