Part Number:66AK2G02
Hello,
I was looking at this post: e2e.ti.com/.../593914
which is linked on the K2G page on TI.com and I have some concerns.
In the K2G reference design, all reset pins are connected to 3V3 logic. In the datasheet, all reset pins have DVDD33 listed as their power supply, and 3.3V as their IO value. In the post linked above, the recommendation is to connect these pins to DVDD18 through a "pull-up" resistor. This seems to contradict both what is done in the reference design and what is shown in the datasheet, despite being in the Keystone II hardware design guide. This is one of many such discrepancies between the Keystone II Hardware Design Guide and the K2G documentation. It seems that many of the requirements for other parts in the family are different than for the K2G (power supplies that exist on one do not exist on the other, for example). For my design, we have been following the advice often given by TI of "When in doubt, follow the datasheet". Can anyone clarify what should be done with these pins?
Thanks,
JL
