A 32.0 MB binary named simply ec, with no model, board number or version anywhere in the name, so its origin cannot be confirmed from the label alone. Despite the name, a 32 MB size is typical of a full SPI BIOS image on a 256 Mbit chip rather than a small standalone embedded controller firmware. Open it in a hex editor or UEFITool to identify the platform, compare it with a dump of the original chip, and only write it with a programmer once you are sure it belongs to the same board.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @laptopchiplevelexpert. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
