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 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
(FT810/FT812)
resistive
touch
screen
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
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
videos
playback
of
motion-JPEG
encoded
AVI
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 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 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
