MSPM0H3216: SYSOSC accuracy over -20°C to 80°C

Hi Ibuki,

Sorry we do not have reliable SYSOSC test data for this limited temperature range.

And as it is not guaranteed for all unpublished data without datasheet, from my understanding, it does not make sense to request the accuracy data during -20 to 80 ℃ right?

Hi expert,

Thank you for your reply.

We understand that this data is not guaranteed, and our customer also understands this.

However, they would like to use this information as a reference for comparison with other MCU vendors.

Specifically, while the requirement is ±1% accuracy, they would like to understand the typical or achievable accuracy (actual performance level) in practice.

With that in mind, could you please confirm whether there is still no information that can be shared, even as reference or typical data?

Thank you very much for your support.

Best regards,

Ibuki Endo

Hi expert,

We measured the frequency error of the LP-MSPM0H3216 using the FCC function in an in-house temperature chamber.

The results are shown below, and it appears that the ±1% requirement is satisfied.

In another thread, we were informed that the following information is available for the MSPM0G3507. Is there any similar information available for the MSPM0H3216?

Since achieving oscillator accuracy comparable to competing products is an important factor in adopting this device, we would greatly appreciate it if you could kindly check this once again.
Thank you very much for your support.

Best regard,
