Is the Zilog Z80 still used?
The Z80 processor was designed in 1976 to compete with Intel’s classic 8080 chip, the predecessor to the chips that most people have in their computers today. Z80s are still used even today, where a high-power processor isn’t needed.
Is Z80 still manufactured?
Zilog still exists making Z80 derived microcontrollers , don’t seem very popular though. Much like the 6502, CDP1802, and other older microprocessors they’ve found a niche that keeps them in production. You can still find them in a number of product types and control systems.
Can you still buy Z80?
You can still get Z80 boards from Zilog: http://www.digikey.com/catalog/en/partgroup/ez80-acclaim/158….
Who made the Zilog Z80?
Federico Faggin
The Z80 is an 8-bit microprocessor introduced by Zilog as the startup company’s first product. The Z80 was conceived by Federico Faggin in late 1974 and developed by him and his 11 employees starting in early 1975….Zilog Z80.

How much did the Z80 cost?
When we came out with the product, we priced the Z80 at $200 a chip, and it took us just a few days to understand from our customers that they needed a lower price to be able to go after the market.
What happened to Zilog?
In August 2017, Zilog and its parent IXYS Corporation were acquired by Littelfuse Inc in exchange for $750 million in cash and stocks.
What computers used the Z80?
The Z80 ended up in thousands of products, including the Osborne I (the first portable, or “luggable,” computer), the KayPro II, the Radio Shack TRS-80, and MSX home computers, as well as printers, fax machines, photocopiers, modems, and satellites.
What is a Z80 microcomputer?
The Z80 is an eight-bit microprocessor introduced in 1976 by Zilog, Inc. Since its release, it has been used in many desktop, embedded, and military computer systems. The first Z80 chips ran at 2.5 MHz, gradually increasing in speed up to 20 MHz.
How many locations can the Z80 CPU address?
8-bit Data Registers The Z80 processor contains 14 general purpose registers which can be used for holding and manipulating data bytes.
Is Z80 better than 6502?
The 6502 was about 3x-3.5x faster than the Z80 at the same clock speed (therefore, the Z80 was usually used with a higher clock speed). Overall, it was / is much nicer to program. The 6502 was derived from the Motorola 6800, and the Z80 was derived from the Intel 8080.
What is the Zilog Z80 8-bit microprocessor?
A May 1976 advertisement for the Zilog Z-80 8-bit microprocessor. The Zilog Z80 CPU is an 8-bit based microprocessor. It was introduced by Zilog in 1976 as the startup company’s first product.
How many employees did Zilog Z80 have?
With the revenue from the Z80, the company built its own chip factories and grew to over a thousand employees over the following two years. The Zilog Z80 was a software-compatible extension and enhancement of the Intel 8080 and, like it, was mainly aimed at embedded systems.
What is a Z80 CPU?
Zilog’s Z80 CPU family of components are fourth-generation enhanced microprocessors with exceptional computational power. They offer higher system throughput and more efficient memory utilization than comparable second and third-generation microproces- sors.
Can the Z80 CPU user manual be used in life support systems?
Z80 CPU User Manual DO NOT USE THIS PRODUCT IN LIFE SUPPORT SYSTEMS. LIFE SUPPORT POLICY ZILOG’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS PRIOR WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF ZILOG CORPORATION.
