Description

The S1D13504F02A2 is a controller IC in the S1D13305 series that is designed to display text and graphics on an LCD panel. It is capable of displaying layered text and graphics, scrolling the display in any direction, and partitioning the display into multiple screens. The IC stores text, character codes, and bit mapped graphics data in an external frame buffer memory. It also includes display controller functions such as transferring data, reading memory data, converting data to display pixels, and generating timing signals for the buffer memory and LCD panel. The S1D13504F02A2 has an internal character generator with 160, 5x7 pixel characters in an internal mask ROM. It supports up to 64, 8x16 pixel characters in an external character generator RAM and up to 256, 8x16 pixel characters in external character generator ROM.
