1.2 Overview Description

The S1D13700 Embedded Memory Graphics LCD Controller can display both text and

graphics on an LCD panel. The S1D13700 allows layered text and graphics, scrolling of the

display in any direction, and partitioning of the display into multiple screens. It includes

32K bytes of embedded SRAM display memory which is used to store text, character

codes, and bit-mapped graphics. The S1D13700 handles display controller functions

including: transferring data from the controlling microprocessor to the buffer memory,

reading memory data, converting data to display pixels, and generating timing signals for

the LCD panel.

The S1D13700 is designed with an internal character generator which supports 160, 5x7

pixel characters in internal mask ROM (CGROM) and 64, 8x8 pixel characters in character

generator RAM (CGRAM). When the CGROM is not used, up to 256, 8x16 pixel

characters are supported in CGRAM.
