The FT801 is a capacitive touch display controller which brings together the functionality and system benefits of Embedded Video Engine (EVE) technology together with the increased brightness, interactivity and vividness associated with capacitive touchscreen technology in order to create sophisticated and dynamic Human Machine Interfaces (HMIs). This LCD controller is packaged in the same 48 pin QFN footprint as the FT800 and promotes architecture re-use for capacitive display needs, whilst providing the key elements seen in the FT800 including 3 in1 functionality (Display, Audio and Touch) and 1/16th pixel resolution, thus lowering BOM costs.
