MSPM0G3507: Would like to improve the frequency accuracy of internal LF(32kHz)

Shunsuke Yamamoto

Part Number: MSPM0G3507

Hi team,

Are there any ways to improve the frequency accuracy of internal LF(32kHz, 3%)? My customer would like to improve it to 1% or 2%

Best regards,

Hi Yamamoto,

This is latext version data from datasheet, does this can meet customer requirement?

If you need more better accuracy, you have to use external LFXT.

Thanks!

Hi Johnson,

Thank you for the reply. It is good to know that LFOSC accuracy is improved from the pre-released datasheet. Please let me check the customer.

Best regards,

Hi Johnson,

Thank you for the answer. May I know the difference between temperature test conditions?

How did you measure these two conditons?

Hi Yamatomo,

If the use case will work in -40C ~ 85C, the accuracy will keep -1.8% ~ 1.4%.

If the workn temperature oncrease, up to 125C, the accuracy will be get a little worse, see datasheet.

Thanks!

Best Regards

Johnson
