# Altera 10AT115N4F40E4SGES: Notes on a Low Speed-Grade Arria 10 GT Variant The Altera 10AT115N4F40E4SGES is part of the Arria 10 GT 1150 group, offering roughly 1,150,000 logic elements, 427,200 logic blocks and 68.9 Mbit of total RAM. It uses the 1517-ball FCBGA (40 x 40 mm) with 600 user I/Os and a 0.87V to 0.93V core, specified for 0°C to 100°C junction temperature. The E4 marking indicates the slowest fabric speed grade in this group, which is typically chosen to minimize cost or power where timing requirements are relaxed. Combined with the high transceiver capability of the GT family, it suits instruments and data acquisition systems that move large amounts of serial data but process it at moderate clock rates. Like other ES-suffix parts, this variant should be checked carefully against Intel documentation for revision, errata and qualification status. The Arria 10 GT line is listed as discontinued by many sources, so availability depends on existing inventory. For existing designs, confirm pin compatibility and that your Quartus Prime version supports the exact device. For new designs, engineers often compare against current Agilex parts for long-term support. When buying, request date codes, original tray packaging and test or inspection reports, and verify markings on receipt, because high-value FPGAs are frequent targets for counterfeiting.
