The data sheet indicates that for a resistor of 91 kΩ at V CC =5 V the oscillator can vary between 190 kHz and 350 kHz resulting in wait times of 52.6 μs and 28.6 μs instead of 37 μs. If a display with the recommended 91 kΩ resistor is powered from 3.3 volts the oscillator will run much slower.
Motorola 6845 CRT controller. The Motorola 6845, or MC6845, is a display controller that was widely used in 8-bit computers during the 1980s. [1] [2] Originally intended for designs based on the Motorola 6800 CPU and given a related part number, it was more widely used alongside various other processors, and was most commonly found in machines based on the Zilog Z80 and MOS 6502.

Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...
A seven-segment display is a form of electronic display device for displaying decimal numerals that is an alternative to the more complex dot matrix displays. Seven-segment displays are widely used in digital clocks , electronic meters, basic calculators, and other electronic devices that display numerical information.
The individual segments of a fourteen-segment display. A fourteen-segment display (FSD) (sometimes referred to as a starburst display or Union Jack display [1] [2]) is a type of display based on 14 segments that can be turned on or off to produce letters and numerals.
A standard-sized 8-pin dual in-line package (DIP) containing a 555 IC.. Integrated circuits and certain other electronic components are put into protective packages to allow easy handling and assembly onto printed circuit boards and to protect the devices from damage.
Windows Display Driver Model (WDDM, [1] initially LDDM as Longhorn Display Driver Model and then WVDDM in times of Windows Vista) is the graphic driver architecture for video card drivers running Microsoft Windows versions beginning with Windows Vista.
