Bridgetek Pte Ltd

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
