MSP430FR2475: Maximum FLL lock time

Part Number: MSP430FR2475

Hello team,

My customer is wondering if the FLL lock time is going to change between using internal reference?
On the datasheet, the lock time of 200ms (TYP) is tested under external crystal.

Also is there any maximum value for the lock time (tFLL)?
If the max value is not characterized, can I get some insight for estimation? Like +/- 20% of typical value?

Best Regards,
Kei Kuwahara

    Hi Kei Kuwahara

    >> if the FLL lock time is going to change between using internal reference?

    we can consider add "REFO start-up time"

    >> If the max value is not characterized, can I get some insight for estimation? Like +/- 20% of typical value?

    the max value is not characterized and garanteed. You can try +20% as the max.

    Thanks
