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 I2C

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 extended operating

temperature range
