S1D13A05

S1D13A05 LCD/USB Companion Chip August 2007

The S1D13A05 is an LCD/USB solution designed for seamless connection to a wide variety of micro-

processors. The S1D13A05 integrates a USB slave controller and an LCD graphics controller with an

embedded 256K byte SRAM display buffer. The LCD controller supports all standard panel types and

multiple TFT types eliminating the need for an external timing control IC. The S1D13A05 includes a

Hardware Acceleration Engine to greatly improve screen drawing functions and the built-in 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 Communications devices and Palm-size PCs.

The S1D13A05 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.

Additionally, products requiring a rotated display can take advantage of the SwivelView

feature which

provides hardware rotation of the display memory transparent to the software application. The

S1D13A05 also provides support for “Picture-in-Picture Plus” (a variable size Overlay window).

The S1D13A05, 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.
