FT800Q-R

EVE，嵌入式视频引擎 FT800FT800 嵌入式视频引擎 EVE 为图形用户界面 GUI 开发重新定义了成本和质量范例。 带有三合一功能，包括显示、音频和触摸操作，工程师们现在可以轻松创建最先进的交互显示系统。 EVE 面向对象的方法无需传统框架的缓冲存储器，因为它逐线渲染图像，达到 1/16 像素分辨率。 只需初始化的对象存储器，然后通过创建并操控较小的显示列表缓冲器，控制对象及其属性即可，甚至使用低端 8 位 CPU 也可完成。 嵌入式音频控制器可播放 MIDI 类声音或 PCM 音频。 EVE 在 ROM 中预装了有用字体和声音集，使其适用于许多应用。主要针对 QVGA 和 WQVGA 分辨率 TFT 显示屏，带并行 RGB 接口 高频振动硬件可提供 18 位接口的 24 位（真色彩）支持 256K 内部对象存储器 8K 字节显示列表中存储多达 2000 个对象， 内置控制器，支持 4 线电阻性触摸面板 PWM 输出，用于可编程显示亮度 防锯齿支持，可提高显示感观 低功率：有源模式下通常为 35mA，睡眠模式下 25uA 小程序（创新机制）允许轻松创建复杂对象（例如模拟时钟） 集成音频输出：播放蜂鸣声、音调或录制音频 SPI 或 I2C 接口到系统微控制器 ### 图像外设

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
