Description
The ECE1117 is a 48-pin 3.3V multi-function compan-
ion device. The ECE1117 communicates with an
upstream host via BC-Link or SMBus.
The ECE1117 is typically mounted in the keyboard
assembly. By mounting the ECE1117 onto the key-
board assembly, the keyboard signals as well as the
touchpad/point stick PS/2 signals and the backlight
PWMs are routed from the keyboard to the mother-
board over a single BC-Link or SMBus connection.
