Character/Graphic TFT LCD Controller---RA8870RA8870 is a TFT LCD controller which supports thecharacter and graphic mixed display. It is designed to meetthe requirement of middle size TFT module up to 640x480 pixels with characters or 2D graphic application. With internal RAM, RA8870 can supports 65K color for 320x240dots TFT Panel, 4K color for 640x240/320x480 display, or 4K color for 320x240 dots with 2-Layers. With external RAM,it supports up to 65K color for 640x480 panel.
The embedded CGROM is capable to display the alphaset of international standard ISO 8859-1/2/3/4. It includes 256x4 characters and can satisfiies almost English or Eurpean language family countries. For graphic usage,RA8870 supports a 2D Block Transfer Engine(BTE) that is compatible with 2D BitBLT function for processing the mass data transfer function. The geometric speed-up engine provides user an easy way to draw the programmable geometric shape by hardware, like line, square and circle. Besides, many powerful functions are combined with RA8870, such as screen rotation function, scroll function, graphic pattern, 2-layer mixed display and font enlargement function. These functions will save user a large of software effort during developement period.
RA8870 is a powerful and cheap choice for color TFT application. To reduce the system cost, RA8870 proivde low cost 8080/6800 MCU I/F, a flexible 4/5-wires Touch Panel controller, PWM for adjusting panel back-light and some GPIOs. With the RA8870 design-in, user can achieve an easy-to-use, low-cost and high performace system compared with the other solution.
