MC141540

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鈥揷hip PLL allows both multi鈥搒ystem

operation and self鈥揼eneration of system timing. It also minimizes the MCU鈥檚

burden through its built鈥搃n 273 bytes display/control RAM. By storing a full

screen of data and control information, this device has a capability to carry out

鈥榮creen鈥搑efresh鈥?without MCU supervision.

Since there is no spacing between characters, special graphics鈥搊riented

characters can be generated by combining two or more character blocks.

Special functions such as character bordering or shadowing, multi鈥搇evel

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鈥?/div>

screen display operation, and serial protocols are implemented in lieu of any

parallel formats to achieve minimum pin count.
