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

Part Number: MSPM0H3216

According to the datasheet, I understand that the SYSOSC accuracy is specified as approximately -2.1% to +1.6% over the full operating temperature range of -40°C to 125°C.
 
However, in the customer application, the operating temperature range is narrower (from -20°C to 80°C), and an accuracy of ±1% is required.
Therefore, I would like to ask the following questions:
 
1. Is it possible to achieve ±1% accuracy for SYSOSC within the temperature range of -20°C to 80°C?
 
2. If ±1% is difficult to achieve, is there any data or guidance indicating how much the accuracy improves compared to the full temperature range specification?
 
I understand that only the datasheet values are guaranteed, but any additional information for design reference would be greatly appreciated.
 
Best regards,
Ibuki Endo

    Hi Ibuki,

    Let me check with our internal team and find if there is any data for -20 to 80

    Hi expert,

    Thank you for checking.

    If there is any internal data available for the -20°C to 80°C range,
    even as a reference (non-guaranteed) value, it would be very helpful for our evaluation.

    We understand that guaranteed specifications may not be available for this limited temperature range,
    but any typical performance data, characterization data, or guidance would be appreciated.

    If no such data exists, please also let us know.

    Best regard,

    Ibuki Endo
