2.1S1D13504 Color Graphics LCD Controller

The S1D13504 is a low cost, low power color/monochrome LCD/CRT controller capable of inter- facing to a wide range of CPUs and LCD displays.

The S1D13504 supports LCD interfaces with data widths up to 16 bits. Using Frame Rate Modulation (FRM), it can display 16 shades of gray on monochrome panels, up to 4096 colors on passive panels and 64K colors on active matrix TFTs. CRT support is handled through the use of an external RAMDAC allowing simultaneous display of both the CRT and LCD displays.

In this design, the S1D13504 has a 3.3V core voltage (Core VDD) and a 3.3V IO voltage (IO VDD).

For complete details on register functionality and programming, refer to the S1D13504 Hardware Functional Specification document number X19A-A-002-xx, and the Programming Notes and Examples, document number X19A-G-002-xx.

2.1.1 Display Buffer

The S1D13504 supports a 512K byte or 2M byte, FPM-DRAM or EDO-DRAM display buffer. On the S5U13504-D9000 evaluation board, a 1Mx16 EDO-DRAM is used to provide adequate memory for all supported display resolutions, and when smaller display sizes are used, to provide multiple “pages” of memory. EDO-DRAM with self-refresh may also be used to provide the lowest possible power consumption during power save modes.
