![]() However, programmability is achieved by changing the software/firmware that runs on the microcontroller chip. Examples of such devices include FPGAs, SPLDs, and CPLDs.Ī microcontroller chip features a fixed digital logic circuit that cannot be modified. The second class of digital devices featured reconfigurable hardware to achieve flexible logic circuit design. Examples of such devices include microcontrollers and microprocessors. The first class consisted of fixed hardware design with reprogrammable software. Two different classes of digital devices emerged to provide programmability. However, over time, the complexity of digital circuits increased thus, programmability became an important feature of modern digital control devices. The early digital electronic devices were rather simple and consisted only of a handful of logic gates. digital signal Types of Digital Electronic Devices Unlike an infinite number of data levels in an analog signal, a digital signal only consists of two logic levels (1s and 0s). In the world of electronics, digital systems have now completely replaced analog electronics due to their lower cost, low noise, better signal integrity, superior performance, and lower complexity. Today almost every computing device in existence incorporates digital ICs and processors. The demand for speedy performance and quick turn-over times led to the development of digital electronics. However, electronics engineers soon found out that analog circuits are highly complex to design and expensive. In the early days of electronics technology, circuits were analogous, such as sound, light, voltage, and current. ![]() However, broadly speaking, electronic devices are in two main categories: analog and digital. Evolution of Digital ElectronicsĮlectronics is a complex field with thousands of electronic devices and components in existence. This article will teach you about an essential digital electronic device known as CPLD (Complex Programmable Logic Device). Electronics is a vast field with many sub-branches. Almost all modern technologies owe their existence to electronics, from the internet and cellular communication to computers and servers. Information technology, the internet, and electronic chips serve as the foundation of the modern digital age.
