Hello,
We would like to know the UART Baudrate accuracy of Y7C65211/CY7C65215.
We can see the difference of baudrate settings like below.
Non-Standard Baud Rates in USB-Serial Bridge Controllers - KBA92442
I have a question about "PCLK = 48 MHz" accuracy.
If the PCLK is Internal 48 MHz OSC, isn't this CLK error added?
Best regards,
Yocchi

Hello,
PCLK is 48MHz +/- 2% accuracy for CY7C65211/215.
Although the KBA you mentioned is not considered the PCLK error, the best way is to include this error for the accurate calculation.
Anyway, to meet the margin within +/-5% is not difficult even if you consider the PCLK error.

Hello Takayama-san,
I agree with you.
PCLK has +/- 2% accuracy.
Thank you.
