MSP430FR2311: msp430fr2311

Michael Pasternak
Prodigy 70 points
Part Number: MSP430FR2311

Tool/software:

Dear Sirs!

I use msp430fr2311 powered from +3.3V,  Clock 8MHz from internal generator and PLL without external crystal.

Now I want to start it from +2.0V and after that power it from +1.9V to meet table 5-1 requirements in datasheet.

My question: Can I still clock it 8Mhz as mentioned above or I have to reduce clock?

And additional question:

This device works in narrow temperature range +15C - +40C.

Can I be sure that in this narrow range msp430fr2311 will start from 1.9V? Typical in table 5-1 is 1.88V? What is a minimum voltage that I need to start device in temperature range +15C - +40C?

Please advice

Best regards

Michael

    Hi Michael

    >> My question: Can I still clock it 8Mhz as mentioned above or I have to reduce clock?

    DCO and PLL can work at all voltage range. you can keep the clock as 8MHz

    >> Can I be sure that in this narrow range msp430fr2311 will start from 1.9V? Typical in table 5-1 is 1.88V? What is a minimum voltage that I need to start device in temperature range +15C - +40C?

    Please follow the data sheet. The voltage should be start from 1.99V (SVSH power-up level max value) and after device is powered, the voltage can be reduced to 1.8V (Supply voltage applied at DVCC pin min value)

    Thanks
