40,000 logic elements — what that buys you
The 10M40DDF256I7G is an Intel MAX 10 FPGA with 40,000 logic elements and 1,290,240 total RAM bits. That density handles medium-complexity state machines, custom serial interfaces, and glue-logic consolidation for a multi-IC board. The 178 user I/O route through a 256-FBGA package (17x17 mm) — enough for a parallel bus plus control lines without needing a larger BGA.
Industrial temperature grade — where it runs
Rated for -40°C to 100°C junction temperature, this variant is the I7 speed/grade — the industrial-temperature sibling of the commercial 10M40DDF256C8G (0°C to 85°C). If your BOM calls for the -40°C low end (outdoor cabinet, engine bay, unheated enclosure), this is the correct order code. The commercial C8G saves a few dollars in a climate-controlled rack but won't guarantee operation below freezing.
Supply rails and programming
Core and I/O banks run on 2.85 V to 3.465 V. The MAX 10 family loads a configuration bitstream via JTAG or from internal flash.
