Industrial CPLD + SDRAM 7-inch touch display solution provides products

Super anti-interference, do not crash spike SSD1963 and RA8875

8080 Timing 16bit parallel bus interface, resolution 800 × 480, 16M color display panel, integrated 8-inch display (memory could ever be used as extended memory). Inside the module using CPLD + SDRAM mode to drive RGB interface display, no further initialization, the bus interface and conversion between RGB interface also provides a range of useful features, details, please refer to the following register descriptions and Demo program.

Support for 51, AVR, STM32 microcontroller and other types of direct drive

Advantages:

Super stability

Job stability of the module with super anti-jamming capability , far beyond driven solutions on the market SSD1963 , SSD1963 interference poor, black and white with crash risk .

Speed and simplicity

This module provides 8 memory can write data to achieve the background , a command instantly switch full screen display data , far beyond the market RA8875 driver program.

Eliminating the need for a general need cumbersome TFT controller initialization code , without initialization , just need to do a reset operation can begin work . Only need to use at least five stacker instruction can operate normally. Greatly simplifies the code , reducing the difficulty of debugging and error probability .

Fast response , can achieve 200ns read and write cycles . Fastest achieve 13 frames in full screen refresh rate , integrated 8MB SDRAM display buffer corresponding to 8 . Showing page register read and write page register set independently , the currently displayed page and the page can be read different pages , facilitate the achievement of the background written, full page fast switching.

Show effects:

TFT driver timing and circuit design have been optimized to ensure accurate color reduction, display a stable , flicker or eliminate channeling color , and provides LED backlight driver , brightness from 0 ( closed ) to 16 ( full ) between regulation.
