SRAM controller
A problem with many SRAM ic's is that they are asynchronous. This is tricky too use in the synchronous FPGA world. This example shows how to interface with a cheap (€4.271)) and high speed (80 MHz) CY7C1041CV33, a 4Mbit (256k x16) SRAM ic, with a MAXII CPLD.Read more »
4.3" PSP LCD
Although the Cyclone EP1C6 does not contain enough ram bits to display graphics on this huge display. It can be used as a large character display, with the capabilities to display up to 1.620 characters (27×60) with a 8x16 font.

VGA
The verilog provided at 4.3_psp_lcd can also be used to drive a VGA display. Only the timing and resolution in h_sync, v_sync and in_picture and the pixel clock in clk should be changed to the correct values as explained in vga_timing.

IBM font
The following 8×16 font was used by IBM in the early PCs and is now widely used in the projects on greenbird. An example usage of the font is shown here: 4.3" PSP LCD.
For easy integration in your projects, you can download a .mif1) file with all 256 characters in it at the bottom of the page.
