UART maximum allowed deviation.

[Michael]

hello everyone,

i am looking for the maximum allowed deviation of the uart. The nRF52832
is clocked with 32 Mhz and has a baud rate of 19200. What is the maximum deviation for the counterpart?

thanks and reagards

HI Michael, 

the UART on the nRF52832 uses the 16MHz clock (PCLK16M).

I could not find any specific number in our internal documentation, however, I think that in general that the nRF52832 should be able to handle up to 3% deviation.

This page covers some of the calculations for determining the maximum allowed deviation.  

Best regards

Bjørn

Hello Bjørn,

thanks for the answer. The counterpart has an accuracy of 0.5%, so it should fit.

best regards,
