FT801
(Embedded Video Engine)
The FT801 is an easy to use graphic controller
targeted for embedded applications to generate high-
quality Human Machine Interfaces (HMIs). It has the
following features:
FT801 functionality includes graphic controller,
audio processing, and capacitive touch controller
interface.
Compatibility mode allows display code to be run
on FT801 or FT800. Extended mode enables multi-
touch capabilities for FT801.
Embedded Video Engine (EVE) with widget
support can offload the system MPU and provide a
variety of graphic features
Built-in graphics operations allow users with little
expertise to create high-quality display
Support capacitive touch screen with up to 5
touches detection
Hardware engine can recognize touch tags and
track touch movement. It provides notification for
up to 255 touch tags.
Enhanced sketch processing
Programmable
interrupt
controller
interrupts to host MPU/MCU
provides
Support for LCD display in WQVGA (480x272) and
QVGA (320x240) formats with data enable (DE)
support mode and VSYNC/HSYNC mode
The FT801 calculates for 8-bit colour despite only
providing pins for 6-bit (RGB-6,6,6); this
improves the half tone appearance
Display enable control output to LCD panel
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
frequency from 8 kHz to 48 kHz. Built-in digital
filter reduces the system design complexity of
external filtering
PWM output for backlight dimming control for LED
Low power consumption for portable application,
24mA active (typical) and 250 uA sleep (typical)
No frame buffer RAM required
Advanced object oriented architecture enables low
cost MPU/MCU as system host using I
2
C and SPI
interfaces
Power mode control allows chip to be put in power
down, sleep and standby states
Supports host interface I/O voltage from 1.8V to
3.3V
Standard serial interface to host MPU/MCU with
SPI up to 30MHz or I²C clocking up to 3.4MHz
Internal voltage regulator supplies 1.2V to the
digital core
-40°C to 85°C extended operating temperature
range
Available in a compact Pb-free, VQFN-48, 7mm X
7mm X 0.9mm package, RoHS compliant
Built-in 12MHz crystal oscillator with PLL providing
48MHz or 36MHz system clock
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 (default RGB data width
of 6-6-6) with 2 bit dithering; configurable to
support resolution up to 512x512 and R/G/B data
width of 1 to 6
Programmable timing to adjust HSYNC and VSYNC
timing, enabling interface to numerous displays
