FT800
(Embedded Video Engine)
The FT800 is an easy to use graphic controller
targeted for embedded applications to generate
high-quality Human Machine Interfaces (HMIs). It
has the following features:
FT800 functionality includes graphic controller,
audio
processing,
and
resistive
touch
controller.
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
Integrated with 4-wire touch-screen controller
incorporating median filtering and touch force
sensing. Hardware engine can recognize touch
tags and track touch movement. It provides
notification for up to 255 touch tags.
Standard serial interface to host MPU/MCU
with SPI up to 30MHz or I²C clocking up to
3.4MHz
Programmable interrupt controller provides
interrupts to host MPU/MCU
Built-in 12MHz crystal oscillator with PLL
providing 48MHz or 36MHz system clock
Video RGB parallel output (default RGB data
width of 6-6-6)
with 2 bit dithering;
configurable to support resolution up to
512x512 and LCD R/G/B data width of 1 to 6
Programmable timing to adjust HSYNC and
VSYNC
timing,
enabling
interface
to
numerous displays
Support for LCD display in WQVGA (480x272)
and QVGA (320x240) formats with data
enable
(DE)
support
mode
and
VSYNC/HSYNC mode
The FT800 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
64 voice polyphonic 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 10-25
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
Internal voltage regulator supplies 1.2V to the
digital core
-40°C
to
85°C
temperature range
extended
operating
Available in a compact Pb-free, VQFN-48,
7mm X 7mm X 0.9mm package, RoHS
compliant
