Hello,
I have two questions.
1. I know that the SCLK and data rate of SPI master can set 8Mbps in case of 48MHz HFCLK.
No matter how the conditions are changed the acutual data rate is less than 4785kbps in SPI slave.
Does it mean that the acutual data rate can not set over 4785kbps in SPI slave?
2. Is the maximum SCLK of SPI master 8Mbps in +1.8V power and 48MHz HFCLK?
Best regards,
Yocchi

Regarding 1), as dogaru_liviu_2439176 mentioned, the answer is YES.
However regarding 2), according to the PSoC 4000S Architecture TRM section 14.2.9 Internally and Externally Clocked SPI Operations, the maximum bit rate is 12Mbps.

Hi Yocchi,
1) Yes, unfortunately. The SPI GUI calculates the actual data rate for master or slave devices.
This can be found in the SPI component datasheet Slave data rate calculations section.
2) No. The maximum SCLK of SPI master powered at +1.8V and 48MHz HFCLK is 4MHz.
Best regards,
Liviu

Hello TakashiM_61,
Thank you for your advice.
I could set 8Mbps in +1.8V and measued it with osilloscope.
Best regards,
Yocchi
