The S1D13A04 is an LCD/USB solution designed for seamless connection to a wide variety of micro-
processors. The S1D13A04 integrates a USB slave controller and an LCD graphics controller with an
embedded 160K byte SRAM display buffer. The LCD controller, based on the popular S1D13706,
supports all standard panel types including the Sharp HR-TFT family of products. In addition to the
S1D13706 feature set, the S1D13A04 includes a Hardware Acceleration Engine to greatly improve
screen drawing functions. The USB controller provides revision 1.1 compliance for applications
requiring a USB client.This high level of integration provides a low cost, low power, single chip solution
to meet the demands of embedded markets requiring USB client support, such as Mobile Communica-
tions devices and Palm-size PCs.
The S1D13A04 utilizes a guaranteed low-latency CPU architecture that provides support for micropro-
cessors without READY/WAIT# handshaking signals. The 32-bit internal data path, write buffer and the
Hardware Acceleration Engine provide high performance bandwidth into display memory allowing for
fast display updates. ‘Direct’ support for the Sharp HR-TFT removes the requirement of an external
Timing Control IC.
Additionally, products requiring a rotated display can take advantage of the SwivelView^TM feature which
provides hardware rotation of the display memory transparent to the software application. The
S1D13A04 also provides support for “Picture-in-Picture Plus” (a variable size Overlay window).
The S1D13A04, with its integrated USB client, provides impressive support for Palm OS^® handhelds.
However, its impartiality to CPU type or operating system makes it an ideal display solution for a wide
variety of applications.
