GENERAL DESCRIPTION
MTV048 is designed for monitor applications to display built-in fonts onto monitor screens. The display operation
occurs by transferring data and controls information from the micro controller to RAM through a serial data
interface. It can execute a full-screen display automatically, as well as specific functions such as character
background, bordering, shadowing, blinking, double height and width, font-by-font color control, button boxes,
frame positioning, frame size control by character height and row-to-row spacing, horizontal display resolution, full-
screen erasing, fade-in/fade-out effect, windowing effect, shadowing on window and full-screen self-test pattern
generator.
MTV048 provides 384 fonts including 360 standard fonts, 16 multi-color fonts and 8 user 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.

Descriptions
- 1 Analog ground. This ground pin is used for internal analog circuitry.
Voltage control oscillator (bit LCD = 0). This pin is used to control
the internal oscillator frequency by DC voltage input from external
I/O
2
low pass filter.
Pixel clock input (bit LCD = 1). This is a clock input pin. MTV048
can be driven by an external pixel clock source for all the logic
inside. The frequency of XIN must be the integral time of pin HFLB.
Bias Resistor (bit LCD = 0). The bias resistor is used to regulate
I/O
3
the appropriate bias current for internal oscillator to resonate at
specific dot frequency.
No connection (bit LCD = 1).
Analog power supply. Positive 5V / 3.3V DC supply for internal
- 4 analog circuitry. And a 0.1uF decoupling capacitor should be
connected across to VDDA and VSSA.
Horizontal input. This pin is used to input the horizontal
I 5 synchronizing signal. It is a leading edge triggered and has an
internal pull-up resistor.
Serial interface enable. It is used to enable the serial data and is
I 6 also used to select the operation of I2C or SPI bus. If this pin is left
floating, I2C bus would be enabled. Otherwise the SPI bus is
enabled.
Serial data input. The external data transfer through this pin to
I 7 internal display registers and control registers. It has an internal pull-
up resistor.
I
8
Serial clock input. The clock-input pin is used to synchronize the
data transfer. It has an internal pull-up resistor.
Digital power supply. Positive 5V / 3.3V DC supply for internal
- 9 digital circuitry and a 0.1uF decoupling capacitor should be
connected across to VDD and VSS.
I
10
Vertical input. This pin is used to input the vertical synchronizing
signal. It is leading triggered and has an internal pull-up resistor.
