MSP430FR2311: Internal Clock stability with Aging

R & D

Dear All,

I want to generate 2.4kHz clock with using this microcontroller with 50% duty cycle.

I wanted to evaluate if its internal frequency will remains stable and will my controller give constant 2.400 kHz clock after 5 years also?

Thanks

Hello,

The stability of the internal frequency will be based upon the specifications detailed in the device's datasheet ( SLASE58D )

Here is a screenshot of the DCO specification:

As far as stability over time, that will be determined by the device's quality specification given on the device's landing page: http://www.ti.com/product/MSP430FR2311/pinout-quality

You will want to view the DPPM / MTBF / and FIT rate for the specific package you plan to incorporate in your design.

Best regards,

Matt

Hello,

If you need an accurate frequency clock, it's recommended to connect an external XT1 to the device to genarate the clock source.
