The First Microprocessor Invention History

Because it was the processor chip used in the Altair 8800, often considered as the first personal computer, the 8080 contributed to the beginnings of the PC revolution. The CP/M operating system (OS) was created for the 8080 microprocessor, and Microsoft's first product, Microsoft BASIC for the Altair, was released. Because millions of applications were built to operate on this platform, these first tools laid the foundation for a software revolution.

In fact, the 8080 was copied because of its popularity. Frederico Faggin left Intel in 1974 to start Zilog and develop the "Super-80," a high-performance 8080-compatible CPU. The Z80 was introduced in July 1976 and quickly became one of the most popular processors ever. In fact, It's still made and marketed today.

The Z80 was not pin-compatible with the 8080, but it combined features like the memory interface and RAM refresh circuits, allowing for the building of cheaper and simpler systems. The Z80 had a superset of 8080 instructions, which let it run all 8080 programs. It also incorporated additional instructions and internal registers; as a result, while 8080 software would work on the Z80, Z80 software would not necessarily run on the earlier 8080. The Z80 had 8,500 transistors and could access 64KB of memory. It operated at 2MHz at first (modern versions run at frequencies ranging from 6MHz to 20MHz). The Z80 is still used in devices like scientific and graphing calculators, and Zilog and other suppliers have produced faster versions with more memory addressing space. The Z80 is still used in audio processing processors, telecommunications, and peripheral controllers.
