S1D13U11 Display Controller Hardware Functional Specification
This is the Hardware Functional Specification for the S1D13U11 External SDRAM LCD Controller. Included in this document are timing diagrams. AC and DC characteristics, register descriptions, and power management descriptions. This document is intended for two audiences: Video Subsystem Designers and Software Developers.
1.2 Overview Description:
The S1D13U11 is a low power color LCD Controller with support for up to 128M-bit external SDRAM memory. The S1D13U11 supports a USB2.0 High-speed device port interface while providing high performance bandwidth into the external display memory allowing for fast screen updates. The S1D13U11 also provides support for multiple display buffers, Picture-in-Picture, Alpha-Blend, and display rotation/mirror.Additionally the S1D13U11 supports one I2C and two SPI serial interfaces. These can be connected to an external touch screen controller and serial flash memory. The S1D13U11 is an excellent solution to connect between the host CPU and LCD panel via the USB port.
Features:
2.1 Frame Buffer：
• Single External 16M-bit, 64M-bit or 128M-bit SDRAM memory support (16-bit bus interface)
• Maximum 96MHz SDRAM clock
2.2 Host CPU Interface：
• USB2.0 device port (1-port)
• HS mode (480Mbps) and FS mode (12Mbps) transfer support
• Embedded FS/HS termination (no need for external components)
• VBUS 5V direct interface (requires protection components)
● Endpoint
• Endpoint 0: For system control (Control transfer)
• Endpoint 1: For command write (Bulk OUT transfer)
• Endpoint 2: For status read (Bulk IN transfer)
• Endpoint 3: For event read (Interrupt IN transfer)
• Endpoint 4: For display data write (Bulk OUT transfer)
• USB protocol control
• Embedded protocol sequencer and 96K-byte work SRAM
• Device class: Vendor class
• Need the download configuration data into work SRAM from USB port or external serial flash
2.3 Input Data Formats：
• RGB 8:8:8 (3-byte/pixel or 4-byte/pixel)
• RGB 5:6:5 (2-byte/pixel)
2.4 Display Mode：
• 24bpp (RGB 8:8:8) or 16bpp (RGB 5:6:5) color depths selectable
2.5 Display Support：
• Active matrix 16/18/24-bit TFT interface
• Maximum 800 x 600 display support (QVGA/WQVGA/HVGA/VGA/WVGA/SVGA)
2.6 Display Features：
• Display Window：
The display window is defined by the size of the LCD display. Complete or partial updates to the display window are done through the Write Window. The write window size and start position are specified in 8 pixel resolution (horizontal) and 1 line resolution (vertical). All window coordinates are referenced to top left corner of the display window (even when rotation or mirror are enabled no host side translation is required). All display updates can have independent mirror, rotation, and transparency settings.
• Picture-in-Picture (PIP) display：
Up to two PIP windows are supported. When enabled the PIP windows are displayed over the Main window. The PIP windows sizes and start positions are specified in 8 pixel resolution (horizontal) and 1 line resolution (vertical). Image scrolling can be performed by changing the start address of a PIP window. The PIP windows do not support a transparent overlay function.
• Alpha-Blend：
Alpha-blending allows two images to be blended to create a new image which can then be displayed using a PIP window. The Alpha-blend image size is specified in 8 pixel resolution (horizontal) and 1 line resolution (vertical). The processing speed of Alpha-blend function varies depending on the image size. Optionally, a single input image can be processed.
• Copy / Fill：
A new window can be copied by Alpha-Blending the image of a window. A new window can be filled by Alpha-Blending a programmed color.
• Mirror / Rotation：
Mirror and 180° counter-clockwise hardware rotation functions are available for image data writes. All windows can have independent rotation and mirror settings. No additional programming is necessary when enabling these modes.
•Multi Buffer：
Multi buffering allows the active display window to be switched between a maximum of 16 buffers. The number of buffers depends on the external SDRAM size and the desired size of the write buffers. Multi buffering allows a simple animation display to be performed by switching the buffers.
• Pixel doubling display：
Display Doubling is available for the main window.
• Virtual display：
Virtual display is available to show the display data which is larger than LCD panel size. The display data can be easily scrolled to the left/right/top/bottom directions.
• Wake-up display：
Wake-up display is available to show quickly the display data which is stored into SDRAM without host CPU support. This function is used when returning from the sleep.
