MOTOROLA SEMICONDUCTOR TECHICAL DATA Product Preview LCD Monitor On-Screen Display II - 16 (LMOSD2-16) CMOS This is a high performance HCMOS device designed to interface with a micro controller unit to allow colored symbols or characters to be displayed onto a LCD monitor. Because of the large number of fonts, 512 fonts including 496 standard fonts and 16 mulit-color fonts, LMOSD2-16 is suitable to be adopted for the multi-language monitor application especially. It minimizes the MCU’s burden through its built-in RAM. By storing a full screen of data and control information, this device has a capability to carry out ‘screen-refresh’ without any MCU supervision. Programmable hatch pattern generator is added for individual pixel inspection. Since there is no clearance between characters, special graphics oriented characters can be generated by combining two or more character blocks. The full OSD menu is formed of 15 rows x 30 columns which can by freely positioned on anywhere of the monitor screen by changing vertical or horizontal delay. Special functions such as character background color, blinking, bordering or shadowing, four-level windows with programmable size, row double height and double width, programmable vertical height of character and row-to-row spacing, and full-screen erasing and Fade-In/Fade-Out are also incorporated. There are 8 color selections for any individual character display with row intensity attribute and window intensity attribute to expand the color mixture on OSD menu.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, Vin and Vout should be constrained to the range VSS ≤ (Vin or Vout) ≤ VDD. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. NOTE: Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the limits in the Electrical Characteristics tables or Pin Description section.
