About the output impedance of Pin Pad for i.MX6ULL

Dear all,

We investigate Drive strength/Slew rate/Speed setting of Pad of i.MX6ULL.

We refer to the following document.
<AN5078>
https://www.nxp.com/docs/en/application-note/AN5078.pdf
 - Table 7. Influence of slew rate and output impedance (P.14)

A parameter of Drive strength and Slew rate is listed in this Table.
However, the Speed setting is not included.

Is there Table which added Speed parameter to Table7?

Best Regards,
Yuuki

Hello Yuki,

>>Is there Table which added Speed parameter to Table7?

   No, there is not.

For PAD's driver strength seting, each pad can be configured, for example "SNVS_TAMPER9" PAD, see reference mauanl, page 1521:  IOMUXC_SNVS_SW_PAD_CTL_PAD_SNVS_TAMPER9 field descriptions


Have a great day,
