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
