MC141543 Advanced Monitor On-Screen Display
CMOS
The MC141543 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 493 bytes 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.
