Hi,

UART Baud Rate error and is not defined in the datasheet. Can you please tell me, what is the Uart buad rate error in LPC55xx series?

Thanks,

Rahul

Hi @rahul_4

I'm not able to understand completely what are you refering to.

Is it possible for you to provide a more detailed explanation to look for the correct answer please?

Best Regards, Miguel.

Hi Miguel,

If the selected UART Baud Rate is 9600, what is the error percentage in the output? Is it within +-1% or +-3%?

For +-1% it will be -> 9504 to 9696 baud rate

Thanks,
Rahul

Hi @rahul_4

There isn't a specification about a deviation on the baudrates generated for the uart. The baudrate deviation could be affected by the precision of the clock.

Best Regards, Miguel.
