原创 彩色LCD控制器，不能没有CX135

1 GENERAL DESCRIPTION
     The CX135A is a low cost highly versatile controller that can display text and graphics on monochrome and color LCD panel. It can scroll the display in horizontal/vertical direction and partition the display into multiple screens. The controller stores text, character codes and graphic data in external frame buffer using standard off-the-shelf SRAM memory.
     All the display functions including transfer of data from/to frame buffer, generating pixels and timing signals for the LCD panel are handled efficiently by the controller facilitating the use of low cost 8-bit microprocessor as the host processor. The CX135A is available in both 1-mm pitch 64-pin QFP and 0.65-mm pitch 64-pin TQFP package.
