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–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.
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.
• Fixed Resolution: 320 (CGA) Dots per Line
• Fully Programmable Character Array of 10 Rows by 24 Columns
• 273 Bytes Direct Mapping Display RAM Architecture
• Internal PLL Generates a Wide–Ranged System Clock
• For High–End Monitor Application, Maximum Horizontal Frequency is
100 kHz (32 MHz Dot Clock)
• Programmable Vertical Height of Character to Meet Multi–Sync
Requirement
• Programmable Vertical and Horizontal Positioning for Display Center
• 128 Characters and Graphic Symbols ROM
• 10 x 16 Dot Matrix Character
• Character–by–Character Color Selection
• A Maximum of Four Selectable Colors per Row
• Double Character Height and Double Character Width
• Character Bordering or Shadowing
• Three Fully Programmable Background Windows with Overlapping
Capability
• Single Positive 5 V Supply
• MC141540P4 is a Replacement for XC141540P with Two Symbols Added
in ROM Addresses ‘5C’ and ‘5E’
