The FT81X is a series of easy to use graphic controllers targeted for embedded applications to generate high-quality Human Machine Interfaces (HMIs). It has the following features:

◇ Advanced Embedded Video Engine (EVE) with high resolution graphics and video playback.

◇ FT81X functionality includes graphic control, audio control, and touch control interface.◇ Pinout backward compatible with FT800 (FT810) and FT801 (FT811).

◇ Support multiple widgets for simplified design implementation.

◇ Built-in graphics operations allow users with little expertise to create high-quality displays.

◇ Support 4-wire resistive touch screen (FT810/FT812).

◇ Support capacitive touch screen with up to 5 touches detection (FT811/FT813).

◇ Hardware engine can recognize touch tags and track touch movement. Provides notification for up to 255 touch tags.

◇ Enhanced sketch processing.

◇ Programmable interrupt controller provides interrupts to host MCU.

◇ Built-in 12MHz crystal oscillator with PLL providing programmable system clock up to 60MHz.

◇ Clock switch command for internal or external clock source. External 12MHz crystal or clock input can be used for higher accuracy.

◇ Video RGB parallel output; configurable to support PCLK up to 60MHz and R/G/B output of 1 to 8 bits.

◇ Programmable timing to adjust HSYNC and VSYNC timing, enabling interface to numerous displays.

◇ Support for LCD display with resolution up to SVGA (800x600) and formats with data enable (DE) mode and VSYNC/HSYNC mode.

◇ Support landscape and portrait orientations.

◇ Display enable control output to LCD panel.

◇ Integrated 1MByte graphics RAM, no frame buffer RAM required.

◇ Support playback of motion-JPEG encoded AVI videos.

◇ Mono audio channel output with PWM output.

◇ Built-in sound synthesizer.

◇ Audio wave playback for mono 8-bit linear PCM, 4-bit ADPCM and µ-Law coding format at sampling frequencies from 8kHz to 48kHz. Built-in digital filter reduces the system design complexity of external filtering.

◇ PWM output for display.

Performance Improvements

◇ Performance Improvements

◇ 500-1000 times faster JPG loading

◇ Pixel clock drawing increased from 4 to 16 pixels per clock

◇ Fetch cull primitives per clock boosted from 1 to 2

◇ Quicker Firmware memory operations (e.g. copy, fill, CRC) due to tuned inner loops

◇ CMD SNAPSHOT hundreds of times faster
