FT800Q-R产品概述
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 30 MHz or I2C clocking up to 3.4 MHz
Programmable interrupt controller provides interrupts to host MPU/MCU
Built-in 12 MHz crystal oscillator with PLL providing 48 MHz or 36 MHz 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, 24 mA active (typical) and 10-25 μA 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 1.8 V to 3.3 V
Internal voltage regulator supplies 1.2 V to the digital core
-40°C to 85°C extended operating temperature range
Available in a compact Pb-free, VFEND-48, 7 mm X 7 mm X 0.9 mm package, RoHS compliant
