Intended to serve as a very simple programmable logic controller and replace and simplify older machinery, the MC14500 cheap price and ease of many uses allowed it to be sold and used in many additional areas. Maximum flexibility was offered by the chip as a result of having no provisions for instruction or data addressing, leaving it to the system designers. |
The MC14500 was also very easy to manufacture. During the early 1980s the chip ease of manufacturability was the reason it entered mass production in a number of large facilities in China (e.g., [[Shanghai Radio Factory 14]]) | The MC14500 was also very easy to manufacture.
