VERVIEW
The S1D13700 Controller displays text and graphics on a midsize, dot-matrix liquid crystal display
(LCD). A very flexible, low-power display system can be configured using the S1D13700 in
combination with various LCD modules. The character code or bitmap display data from the
microprocessor is temporarily stored in frame buffer memory, then periodically read out and
converted into LCD module signals for output to the LCD. Its abundant command functions make
it possible to overlay the text and graphic screens, scroll the screen in any direction (except in
grayscale mode), and split the screen for multi-window display, as well as display pictures in
grayscale mode. Moreover, the embedded-type 32-KB SRAM display buffer, built-in LCD module
control circuit, and high-speed character generator allow you to build an LCD control block with
only a few external circuits.
