MOTOROLA
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. There
are three different resolutions that users can choose. By changing the number
of dots per horizontal line to 320 (CGA), 480 (EGA) or 640 (VGA), smaller
characters with higher resolution can be easily achieved.
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 are expected for normal on–
screen display operation, and serial protocols are implemented in lieu of any
parallel formats to achieve minimum pin count.
