Bin Hammam and vice-president Jack Warner will also be at Sunday's hearing to answer charges of bribery.
Blatter issued a statement saying: "I cannot comment on the proceedings that have been opened against me. The facts will speak for themselves."
The ethics committee are bound by their rules to investigate any complaint by an executive committee member under article 16 of the ethics code.
Bin Hammam and Warner face allegations from executive committee member Chuck Blazer that they offered bribes at a meeting of the Caribbean Football Union (CFU) on 10 and 11 May.
A file of evidence claims bundles of cash of up to $40,000 were handed over to members of the CFU at the meeting in Trinidad.
