FT81x
(Advanced Embedded Video Engine)
The FT81x is a series of easy to use graphic
controllers targeted at 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
(FT810) and FT801 (FT811).
with
FT800
Support for LCD display with resolution up to
SVGA (800x600) and formats with data enable
(DE) mode or 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 8 kHz to 48 kHz.
Built-in digital filter reduces the system design
complexity of external filtering
PWM output for display backlight dimming
control
Advanced object oriented architecture enables
low cost MPU/MCU as system host using SPI
interfaces
Support SPI data lines in single, dual or quad
mode; SPI clock up to 30MHz
Power mode control allows the chip to be put in
power down, sleep and standby states
Supports I/O voltage from 1.8V to 3.3V
Internal voltage regulator supplies 1.2V to the
digital core
Build-in Power-on-reset circuit
-40°C to 85°C extended operating temperature
range
Available in a compact Pb-free, VQFN-48 and
VQFN-56 package, RoHS compliant
Support multiple widgets for simplified design
implementation
Built-in graphics operations allow users with
little expertise to create high-quality displays
Support
4-wire
(FT810/FT812)
resistive
touch
screen
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
interrupts to host MCU
controller
provides
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
