A generic EC.bin file of 2 MB in BIN format, and the name does not state any device, board or version. It is most likely an embedded controller firmware image, which handles power-on, battery charging, keyboard and fan control on laptops. Without a matching board number it should not be flashed blindly. Compare it with the dump read from the original chip, confirm the target chip capacity matches 2 MB, and keep a backup of the existing EC or BIOS contents before writing anything with a programmer.
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 @bioshub. Enginerys does not host this file.
How to open a .bin 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 →
