# Altera 10AT115U3F45E2SGES: Another 1.15M LE Arria 10 GT ES Option 10AT115U3F45E2SGES is a related Arria 10 GT engineering-sample SKU in the same 1.15M LE / 624 I/O / 1932-FCBGA class with 0.87–0.93 V core supply. U3/E2 vs U4/E4 suffixes encode speed grade and feature/test differences that matter for timing closure. Always compile against the exact OPN in Quartus rather than assuming pin-compatible ES parts are interchangeable for timing. Use ES silicon for lab bring-up; migrate to fully qualified production OPNs for volume.
