Controller/ MCU > CEC

Part Number:EPF011C

Overview

EPF011C is an HDMI CEC (Consumer Electronics Control) and EDID controller. The chip receives commands from Host (the main MCU) through IIC interface and handles CEC services for Host. CEC is a mechanism that provides high-level control functions between all of the various audiovisual products in an user’s environments. CEC is specified in Supplement 1 in HDMI specification. EPF011C is compliant with HDMI 1.3b CEC specification. EPF011C effectively reduces the loading of Host and provides an ideal and quick CEC solution.

EPF011C-T also supports 256 bytes on-chip EDID EE and provide DDC interface. User can pre-program the EDID contents into the on-chip EDID EE without the need of using a dedicated EDID EE chip to save system cost.
