System Overview
Positioned midway between the MPU and LCD panel, the S1D13700 enables the sending and
receiving of control commands and data, and access of registers by the MPU for display, thus
making it possible to control up to 32 Kbytes of internal display memory (VRAM).
Moreover, because the S1D13700 has a built-in a control circuit for LCD units, it is possible to
take full advantage of the features of midsize, dot-matrix liquid crystal display units without using
any external circuit.
Figure 1-1 Block diagram of the S1D13700
The S1D13700 divides the display memory space into the four areas shown below. When this
conguration is combined with the layered (overlaid) display and exible scroll functions of the
S1D13700, it is possible to greatly reduce the MPU load when inverting or underlining text,
displaying graphs with text, or creating simple animation.
The S1D13700 uses the display memory space by dividing it into the four areas shown below to
realize the layered display functions using only a single controller.
