It is an System Management BIOS information field. This is a Microsoft document that explains SMBios support status in Windows.

"EC" is deacronymized as "Embedded Controller" and means a chip that processes some model-specific hardware events and also interprets ACPI pseudocode. (At least everything I found on the web refers to EC in this way. Also EC references are mostly found with ThinkPad laptops. This is a small explanation of what it does on ThinkPads).
