S1D13708 Embedded Memory LCD Controller
July 2001
The S1D13708 is a color/monochrome LCD graphics controller with an embedded memory / display
buffer. Targeted at PDA and Cell Phone applications, the S1D13708 ‘directly’ interfaces to numerous
TFT panels and incorporates a minimum pin-count CPU interface thereby making it an ideal solution for
an LCD Module.
This high level of integration combined with a 1.8V Core, provides a low cost, low power, single chip
solution to meet the demands of embedded markets such as Mobile Communications devices and
Palm-size PCs, where board size and battery life are major concerns.
The embedded display buffer greatly improves overall system performance as the S1D13708 handles
all of the display functions directly with very little interaction from the processor.
The S1D13708 provides very flexible display features, from our patented SwivelView
TM
technology
which provides hardware rotation of the displayed image, to our Ink Layer with transparency, to our
“Picture-in-Picture Plus” feature which allows two active variable size display ‘windows’.
The S1D13708 provides impressive support for Mobile Communication devices and Palm OS
handhelds, however its impartiality to CPU type or operating system makes it an ideal display solution
for a wide variety of applications.
