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 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. • Three Selectable Resolutions: 320 (CGA), 480 (EGA) or 640 (VGA) Dots per Line • Fully Programmable Character Array of 15 Rows by 30 Columns • 493 Bytes Direct Mapping Display RAM Architecture • Internal PLL Generates a Wide–Ranged System Clock • For High–End Monitor Application, Maximum Horizontal Frequency is 110 kHz (70.4 MHz Dot Clock at 640 Mode) • Programmable Vertical Height of Character to Meet Multi–Sync Requirement • Programmable Vertical and Horizontal Positioning for Display Center • 128 Characters and Graphic Symbols ROM (Mask ROM is Optional) • 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 • Provides a Clock Output Synchronous to the Incoming H Sync for External PWM • M_BUS (IIC) Interface with Address $7A • Single Positive 5 V Supply
