How is the I/O frequency of the nRF52805

[Tom.Fu]

Hi Support Team

What is the maximum GPIO frequency of the nRF52805, I could not find any information about this in the nRF52805 product specification file, which GPIOs of the nRF52805 have the maximum frequency? I can find this kind of information in the nRF52840 product specification file like the below screenshot showing. Many thanks.

Hi 

The peripheral clock in the nRF52 series is running at 16MHz, which also limits the toggle rate of any GPIO to 16MHz. 

This means the maximum clock speed you will see on any pin is 8MHz, which is the maximum frequency for the SPI and PWM peripherals for instance. 

Best regards
