On-Screen Display Controller for CRT/LCD Monitor
FEATURES
• Horizontal SYNC input up to 150 KHz.
• On-chip PLL circuitry or external pixel clock input up to
150 MHz.
• Software control for CRT/LCD applications.
• Programmable R,G,B input level for timing measurement
among HFLB, VFLB, RIN, GIN and BIN for auto sizing.
• Full screen self-test pattern generator.
• Programmable Hor. resolutions up to 1524 dots per line.
• Full-screen display consists of 15 (rows) by 30 (columns)
• Two font size 12x16 or 12x18 dot matrix per character.
• True totally 544 mask ROM fonts including 512 standard
fonts and 32 multi-color fonts.
• Character button boxes with programmable box length.
• Double character height and/or width control.
• Programmable positioning for display screen center.
• Character bordering, shadowing and blinking effect.
Character (per row) and window intensity control.
• Row to row spacing control to avoid expansion distortion.
• 4 programmable windows with multi-level operation.
• Shadowing on windows with programmable shadow
width/height/color.
• Programmable adaptive approach to handle H, V sync
collision automatically by hardware.
• Software clears bit for full-screen erasing.
• Fade-in/fade-out or blending-in/blending-out effects.
• Compatible with SPI bus or I2C interface with slave
address 7AH/7BH (slave address is mask option).
• 16-pin or 20-pin PDIP/SOP package.
GENERAL DESCRIPTION
MTV038 is designed for CRT/LCD monitor applications
to display built-in characters or fonts onto monitor screens.
The display operation occurs by transferring data and con-
trol information from the micro-controller to RAM through a
serial data interface. It can execute full-screen display
automatically, as well as specific functions such as charac-
ter background, bordering, shadowing, blinking, double
height and width, font by font color control, character but-
ton boxes, frame positioning, frame size control by charac-
ter height and row-to-row spacing, horizontal display
resolution, full-screen erasing, fade-in/fade-out effect, win-
dowing effect, shadowing on window and full-screen self-
test pattern generator.
MTV038 provides 544 fonts including 512 standard
fonts and 32 multi-color fonts and 2 font sizes, 12x16 or
12x18 for more efficacious applications. The full OSD
menu is formed by 15 rows x 30 columns, which can be
positioned anywhere on the monitor screen by changing
vertical or horizontal delay.
The auto sizing video measurement module measure
the timing relationship among HFLB, VFLB, and R, G, BIN
with 12-bit resolution at the speed related to the OSD pixel
clock. And the R, G, BIN input level can be programming
by software. MCU can get the measurement data, active
video, front porth and back porth, through I2C bus read/
write operation to keep the appropriate display size and
center.
