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...
