FEATURES
Super On-Screen-Display
GENERAL DESCRIPTION
• Horizontal sync input may be up to 120 KHz.
• On-chip PLL circuitry up to 96 MHz.
• Programmable horizontal resolutions up to 1524 dots per dis-
play row.
• 942 bytes display registers to control full screen display.
• Full screen display consists of 15 (rows) by 30 (columns) char-
acters.
• 12 x 18 dot matrix per character.
• Total 256 characters and graphic fonts including 248 mask
ROM fonts and 8 programmable RAM fonts.
• 8 color selectable maximum per display character.
• Double character height and/or width control.
• Programmable positioning for display screen center.
• Bordering, shadowing and blinking effect.
• Programmable vertical character height (18 to 71 lines) control.
• Row to row spacing register to manipulate the constant display
height.
• 4 programmable background windows with multi-level operation
• Software clears for display frame.
• Polarity selectable to Hsync and Vsync inputs.
• Auto detection for input edge bounce distortion between Hsync
and Vsync inputs.
• Half tone and fast blanking output.
• Software force blank function for external display.
• 8 channels 8 bits PWM D/A converters output.
• Provide a clock output synchronous to the incoming Hsync for
external PWM D/A.
• Compatible to SPI bus or I2C interface.
• I2C interface with address 7AH (Slave address is mask option).
• 16 pins, 20 pins or 24 pins PDIP package.
MTV018 is designed for monitor applications to dis-
play the built-in characters or fonts onto monitor
screen. The display operation is by transferring data
and control information from micro controller to RAM
through a serial data interface. It can execute full
screen display automatically and specific functions
such as character bordering, shadowing, blinking,
double height and width, font by font color control,
frame positioning, frame size control by character
height and horizontal display resolution, and window-
ing effect. Moreover, MTV018 also provide 8 PWM
DAC channels with 8 bits resolution and a PWM
clock output for external digital to analog control.

The data transmission is permitted to change from format (a) to format (b) and (c), or from format (b) to format
(a), but not from format (c) back to format (a) and (b). The alternation between transmission formats is config-
ured as the state diagram shown in Figure 3 on page 5.

3.2 Address bus administrator
The administrator manages bus address arbitration of internal registers or user fonts RAM during external
data write in. The external data write through serial data interface to registers must be synchronized by inter-
nal display timing. In addition, the administrator also provides automatic increment to address bus when exter-
nal write using format (c).
3.3 Vertical display control
The vertical display control can generates different vertical display sizes for most display standards in current
monitors. The vertical display size is calculated with the information of double character height bit(CHS), verti-
