S1D13709
Embedded Memory Graphics LCD Controller
■ DESCRIPTIONS
The S1D13709 is a simple, multi-purpose Graphics/Text LCD Controller with 32KByte embedded SRAM display buffer which
supports both TFT and STN panels. Designed as a functional replacement for the S1D13700, the S1D13709 has a TFT
interface supported up to WVGA panel. Also from software point of view, a system using STN panel designed with
the S1D13700 can be easily migrate to a TFT panel system with the S1D13709 because the register set of the
S1D13709 is fully compatible with the S1D13700.
The S1D13709 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 S1D13709 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 S1D13709 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.
