Other Parts Discussed in Thread: TPS65982D

Hi Sir,

According to TPS65982DA datasheet, the SPI CLK spec is as below.

My customer use Winbon's SPI ROM.

But they found that the CLK which TPS65982D issued does not meet this spec.

Could we adjust this clock frequency over TPS65982D?

Or 11.7Mhz is acceptable?

Hi Jim,

Is there a specific issue that you are seeing with loading the firmware from the SPI flash? Generally as long as you are within the SPI Flash supported speed you should be okay.

Hi Jacob

Because my customer need to do the test report, he need to check each signal can meet the spec.
It seems like 11.71MHz is lower than the spec minimum 11.82MHz.
So do you mean that it is an acceptable value?

Thank you

Hi Jim,

Yes that is correct. What is the top marking on the device that was tested? Do you know which patch version they are using?
