MC141540

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Monitor On-Screen Display CMOS The MC141540 is a high performance HCMOS device designed to interface with a microcontroller unit to allow colored symbols or characters to be displayed on a color monitor. The on–chip PLL allows both multi–system operation and self–generation of system timing. It also minimizes the MCU’s burden through its built–in 273 bytes display/control RAM. By storing a full screen of data and control information, this device has a capability to carry out ‘screen–refresh’ without MCU supervision. Since there is no spacing between characters, special graphics–oriented characters can be generated by combining two or more character blocks. Special functions such as character bordering or shadowing, multi–level windows, double height and double width, and programmable vertical length of character can also be incorporated. Furthermore, neither massive information update nor extremely high data transmission rate ar...
