Bridgetek FT800 Embedded Video Engine

Bridgetek Embedded Video Engine (EVE) features an initial chip offering of the FT800, which addresses the need for easy-to-design, advanced forms of human-machine interaction. EVE provides a high-quality graphic solution with 3-in-1 functionality for graphical user interface (GUI) development. The FT800 combines display, audio, and touch operations into a single chip, providing an optimized solution that reduces power, board area, BOM costs, and much more. With these operations, engineers now have an advanced solution to easily create and output state-of-the-art interactive display systems.

Targeted at intelligent QVGA and WQVGA TFT display panels, EVE's object-oriented approach renders images in a line-by-line fashion with 1/16th of a pixel resolution, eliminating the expense of traditional frame buffer memory. The FT800 integrates with system MCUs via a low bandwidth serial interface, allowing for lower spec/cost MCUs to be used in the design. The controller's functionality sets new industry benchmarks, supporting 4-wire resistive touch sensing with built-in intelligent touch detection and an embedded audio processor that allows midi-like sounds, combined with pulse code modulation (PCM) for audio playback. The combination of display, audio, and touch on a single-chip solution enables engineers to produce GUIs that deliver compelling user experiences.
