Aha, what a kind of obscure obfuscation! Why they requested this difference from ITE?
It's good to know in case of replacement, improper chip would release a magic smoke then, haha:)
My chip marking is exactly:
IT8728F
1118-DXA
AC07KDGB
Does also exist any other irregular variants like for Asus or so?
Do you have some newer version of datasheet than 0.42?
