The FT813Q-T is an embedded video engine (EVE) IC developed by Bridgetek (formerly FTDI). It's designed to simplify the development of Human Machine Interfaces (HMIs) by handling graphics rendering, audio output, and touch control. This chip allows designers to create rich, interactive displays without requiring extensive low-level programming.

Applications

• Industrial control panels
• Home automation systems
• Point-of-sale (POS) terminals
• Medical devices
• Consumer electronics with display interfaces

Features

• Embedded graphics engine: Handles complex graphics rendering tasks, freeing up the host microcontroller.
• Audio output: Integrated audio codec for sound effects and audio playback.
• Touch controller: Supports capacitive touch screens for interactive input.
• SPI interface: Connects to a host microcontroller via a simple SPI interface.
• QVGA to WVGA display support: Supports a wide range of display resolutions.
• Anti-aliasing: Provides smooth, high-quality graphics.
• Object-oriented approach: Simplifies graphics programming.

Benefits

• Reduced development time: Simplifies HMI development with its integrated graphics engine and object-oriented approach.
• Lower system cost: Reduces the need for a powerful host microcontroller by handling graphics rendering on-chip.
• Improved user experience: Enables the creation of rich, interactive HMIs with smooth graphics and responsive touch control.
• Faster time-to-market: Accelerates product development by simplifying the HMI design process.
• Simplified integration: Easy to integrate into existing systems via the SPI interface.

Additional Details

The FT813Q-T uses a command-based architecture, where the host microcontroller sends commands to the EVE chip to perform specific graphics operations. The EVE chip then handles the rendering and display of the graphics. This approach simplifies the programming model and reduces the amount of code that needs to be written on the host microcontroller. The chip supports a wide range of graphics primitives, including lines, rectangles, circles, and text. It also supports image and video playback. The touch controller supports both single-touch and multi-touch input. The audio output can be used to generate sound effects, play music, or provide voice prompts. The FT813Q-T is available in a QFN package and operates over a wide temperature range.
