Myson MTV018N-27

GENERAL DESCRIPTION

MTV018 is designed for monitor applications to display 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 windowing effect. Moreover, MTV018 also provide 8 PWM DAC channels with 8 bits resolution and a PWM clock output for external digital to analog control
