The Zilog Z80 is an 8-bit microprocessor designed by Zilog that played an important role in the evolution of early computing. Launched in 1976, it was designed to be software-compatible with the Intel 8080, offering a compelling alternative due to its better integration and increased performance.
The Z8000, introduced that year, was the company's first 16-bit microprocessor. [7] The company became a subsidiary of Exxon in 1980. Exxon initially acquired 51 percent of the company before buying it outright; [8] however, the management and employees bought it back in 1989, led by Edgar Sack. [9] Zilog's iconic 8-bit processor, the Z80.
The Zilog Z80 was the first microprocessor created by Zilog, the first company entirely dedicated to microprocessors. It was started by Federico Faggin and Ralph Ungermann in November 1974. Faggin was Zilog's president and CEO until the end of 1980 and he conceived and designed the Z80 CPU and
The Zilog eZ80 is an 8-bit microprocessor designed by Zilog as an updated version of the company's first product, the highly-successful Zilog Z80. The eZ80 is binary compatible with the Z80, but operating almost three times faster at the same clock frequency .

The NEC μCOM series is a series of microprocessors and microcontrollers manufactured by NEC in the 1970s and 1980s. The initial entries in the series were custom-designed 4 and 16-bit designs, but later models in the series were mostly based on the Intel 8080 and Zilog Z80 8-bit designs, and later, the Intel 8086 16-bit design.
The Zilog Z80000 is an unreleased 32-bit processor designed by Zilog and completed in 1986. The Z80000 is a 32-bit expansion of the 16-bit Zilog Z8000 with multiprocessing capability, a six-stage instruction pipeline, and a 256-byte cache. It can address 4 gigabytes of RAM, but cannot execute code written for the Z8000 or Z80.
