thanks for your help.

I have done an trial for EPM240T100c5n, if i apply 1.74v on VCCIO and VCCINT, it works very well.

I don't know if the internal ldo will be disabled if 1.8V is applied on vccint. the difference is that epm240 will consume more power than epm240g when 1.8V is applied on vccint.

is there an FAE that know the details about it issue?
