SEMICONDUCTOR TECHNICAL DATA

CMOS

P SUFFIX

PLASTIC DIP

CASE 648

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.

ORDERING INFORMATION

MC141540P4 Plastic DIP

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 are expected for normal on–

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

parallel formats to achieve minimum pin count.
