MTV018
GENERAL DESCRIPTION
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.
