Kinetis K8 FlexIo max serial clock speed

AlainRIMLINGER — Mon, 15 Feb 2016 10:35:36 GMT

Hello. I would like to connect K8x Kinetis secure licrocontroller with SPI at higher rate than 24MHz. Can I use FlexIo interface to achieve this ? What would be the max speed of the FlexIO interface serial clock ? Thank you very much. Regards

Hi Alain RIMLINGER,

From the K8X datasheet, you may know, the SPI operation frequent is 30Mhz, I don't know what the SPI frequent you want to achieve.

If you want to use the FlexIO, the clock speed may be higher, because the FlexIO clock can up to 150Mhz.

More detials about the FlexIO, please refer to this post:

Understanding FlexIO

Wish it helps you!

If you still have question, please contact with me!

Have a great day,

Jingjing
