OSD PRESSOR FOR MONITOR (PRELIMINARY)
S5D2510
PRODUCT SUMMARY
INTRODUCTION
S5D2510 is a stand-alone OSD Processor, which is used to display monitor adjustment or status information as a
certain character or symbol on screen. Its basic operation includes making the R/ G/ B signal for the character or
symbol by controlling the internal memory, synchronizing it with the horizontal flyback signal, and mixing it with
the main video signal in the video AMP IC. The font data for making the character or symbol is stored in the
internal ROM. It is accessed and controlled by the control data, transmitted from the micro controller through the
I2C bus. The chip contains internal PLL circuitry, so all timing control signals, including the system clock, are
synchronized with the horizontal flyback signal.
FEATURES
• Enough font to support multiple language :
• Wide Operating (Horizontal) Frequency Range : 30kHz 120kHz
• 640, 800, 1024 and 1280 Dots/ Line
• Pixel Frequency provided by On-Chip PLL : 19.2MHz 153.6MHz
• General Font Matrix : 12 × 18
• Fully Programmable Display Area : 15 Rows × 30 Columns
• Popular MCU Interface : I2C Protocol
• Built in 1K-byte SRAM
• Selectable Character Color (Up to 16 Color) : Font basis
• Selectable Raster Color (Up to 16 Color) : Font basis
• Programmable and Auto-adjustable Vertical Height of Character : Range 18 63
• Character Blinking and Shadowing : Font basis
• Programmable Symmetrical Row to Row Spacing : Range 0 31
• Horizontal Starting Position : 256 different positions (6 dots for each step)
• Vertical Starting Position : 256 different positions (4 scan line for each step)
• Scrolling : Effect where 1 character line is scrolled up or down
• 4 Programmable Window Function and Window Priority Control
• Selectable Window Shadow Width : H/ V 2, 4, 6 and 8 Dots
• Supports Background Video Transparency : Font basis or Window basis
• Full White Pattern Generation for Manufacturing Mode
• Auto Character Height Control

Description
This output pin signifies the color intensity. If you set the intensity
control bit to '1' (high) and use with the Pre-AMP supporting
intensity function, this pin outputs logic high while the specified
character or raster is being displayed. If this pin's output is high,
the color level is reduced to half and shows a difference in color
level from when it is low, allowing a 16-color choice when this
intensity pin and R/ G/ B output are combined. For example, if R,
G, B are all high, white is output. If you set the INT bit to '1' (high),
the color level becomes reduced to half and outputs gray.
+5V Supply Voltage for Digital Part
* In the table above, only HFLB and VFLB's active column is low. This means that HFLB and VFLB are set so
that they are inputted as active low in default. For more information, please refer to 'Register Descriptions (13p)'.

* As you can see the "Figure 7, 8 : SDA/ SCL Timing Chart", just the time when the SCL is low, the SDA can be
occurred transition. Therefore, you must program MCU not to occur timing violation.
