Safe temperature range for nRF52840 - nRF9160 UART 115200 without external crystals for HF clocks

[Michal Mühlpachr]

Hi,

what is safe temperature range for nRF52840 - nRF9160 UART communication on 115200 baudrate without external crystals for HF clocks please ?

Thank you.

Hi

As long as the other components you're using supports these temperatures the nRF52840 and nRF9160 are both able to operate safely from -40°C to 85°C.

Best regards,

Simon

Hi,

thank you, that is clear.

But we need to now, whether UART clocked from internal RC (without external crystal) in both chips will not mismatch each other to inject bit errors between TX and RX on 115200 baudrate 8N1 in whole temperature operating range from -40°C to 85°C.

Regards,

Michal
