AMI Embedded Controller (EC) Firmware Solution
Not Your Father’s Keyboard Controller...
Keyboard Controller The embedded controller (EC) is an essential component in modern mobile, ultra-mobile and
Firmware with ACPI Embedded computer systems. An efficient EC sub-system enables energy-conscious designs
Embedded Controller to obtain dramatic power savings.
The latest EC silicon feature higher processing power and complex features, requiring a more
Functionality robust firmware solution. With over 25 years of experience in BIOS and keyboard controller
