Although used in that role, the Z80 also became one of the most widely used CPUs in desktop computers and [computer]s from the 1970s to the mid-1980s.
It was also common in military applications, musical equipment such as synthesizers (like the Roland Jupiter-8), and coin operated arcade games of the late 1970s and early 1980s including Pac-Man. Zilog licensed the Z80 to the US-based Synertek and Mostek, which had helped them with initial production, as well as to a European second source manufacturer, SGS.
The Z80 was conceived by Federico Faggin in late 1974 and developed by him and his 11 employees starting in early 1975.

The first working samples were delivered in March 1976, and it was officially introduced on the market in July 1976.
Some of the Z80 support and peripheral ICs were under development at this point, and many of them were launched during the following year. Early Z80s were manufactured by Synertek and Mostek, before Zilog had its own manufacturing factory ready, in late 1976.

Though, due to the collapse of Soviet microelectronics in the late 1980s, there are many more T34BM1s than КР1858ВМ1s. ===Derivatives=== Compatible with the original Z80: Hitachi developed the HD64180, a microcoded and partially dynamic Z80 in CMOS, with on chip peripherals and a simple MMU giving a 1 MB address space.
On those, it is possible to run assembled or compiled user programs in the form of Z80 machine-language code. In the late 1980s, a series of Soviet landline phones called "AON" featured the Z80; these phones expanded the feature set of the landline with caller ID, different ringtones based on the caller, speed dial and so forth.

Another notable and unique machine is the DEC Rainbow 100, which featured both an Intel 8088 and a Z80 CPU, to support either the 8-bit CP/M-80 applications, running on the Z80, or CP/M-86 (or limited MS-DOS) applications running on the 8088. In 1981, Multitech (later to become Acer) introduced the Microprofessor I, a simple and inexpensive training system for the Z80 microprocessor.
The Sharp PC-1500, a BASIC-programmable pocket computer was released in 1981, followed by the improved Sharp PC-1600 in 1986 and the Sharp PC-E220 in 1991.

Zilog was later by a few years than Intel (with its 80C85) to produce a low-power CMOS CPU, and this resulted in the Intel chip first appearing in use with battery-powered portable computers, such as Tandy/Radio Shack's TRS-80 Model 100 laptop from April 1983, which was designed and built by Kyocera and also sold by Kyocera, Olivetti, and NEC in various design variations under different names.

While the laptop market in subsequent years moved to more powerful Intel 8086 processors and the MS-DOS operating system, light-weight Z80-based systems with a longer battery life were still being introduced, such as the Cambridge Z88 in 1988 and the Amstrad NC100 in 1992.

The last two were the Laser PC5 and PC6. The Cidco MailStation Mivo 100, first released in 1999, was a stand-alone portable email device, with a Z80-based microcontroller. Starting with the TI-81 in 1990, Texas Instruments has manufactured a long line of graphing calculators based on the Z80.

The Z80-derived Z8S180 also found its way into an early pen-operated personal digital assistant, the Amstrad PenPad PDA600 in 1993.
These products are today second sourced by Zilog. The 32-bit Z80 compatible Zilog Z380, introduced 1994, is used mainly in telecom equipment. Zilog's fully pipelined Z80 compatible eZ80 with an 8/16/24-bit word length and a linear 16 MB address space was introduced in 2001.

TI also produced a line of pocket organizers (ended in 2000) using Toshiba processors built around a Z80 core; the first of these was the TI PS-6200 and after a lengthy production run of some dozen models culminated in their PocketMate series.
However, it was not until the fully pipelined eZ80 was launched in 2001 that those instructions finally became approximately as cycle-efficient as it is technically possible to make them, i.e.
