FT812Q-T
Overview
The FT812Q-T is an advanced Embedded Video Engine (EVE) controller designed to manage high-quality graphics, audio, and touch interfaces over a simple SPI or I2C connection. It features an object-oriented architecture that allows engineers to create sophisticated user interfaces by manipulating graphic objects rather than frame buffers. With 1024KB of dedicated RAM and support for landscape and portrait orientations, it is optimized for small to medium-sized displays.
Why Choose This Part
The EVE architecture significantly reduces the processing load on the host MCU by handling graphics rendering, touch tracking, and audio playback internally. It operates at a low run current of 22mA and includes advanced power management modes like Sleep and Powerdown for energy-sensitive designs. The 56-QFN package provides a compact footprint while offering comprehensive features like a built-in sound synthesizer and PWM backlight control.
Applications
Key Specifications
Getting Started
Developers can begin evaluation using Bridgetek's VM800B or VM810C development modules which provide a direct interface to the FT81x series. Software development is supported through the EVE Screen Editor and comprehensive C-based libraries that provide high-level commands for drawing widgets and handling touch events. Ensure the SPI clock does not exceed the 60MHz maximum frequency during high-speed data transfers.
