IEEE Spectrum: 25 Microchip
IEEE Spectrum: 25 Microchips That Shook the World http://www.spectrum.ieee.org/print/8747 Sponsored By Select Font Size: A A A 25 Microchips That Shook the World By Brian R. Santo This is part of IEEE Spectrum 's Special Report: 25 Microchips That Shook the World . In microchip design, as in life, small things sometimes add up to big things. Dream up a clever microcircuit, get it sculpted in a sliver of silicon, and your little creation may unleash a technological revolution. It happened with the Intel 8088 microprocessor. And the Mostek MK4096 4-kilobit DRAM. And the Texas Instruments TMS32010 digital signal processor. Among the many great chips that have emerged from fabs during the half-century reign of the integrated circuit, a small group stands out. Their designs proved so cutting-edge, so out of the box, so ahead of their time, that we are left groping for more technology clichés to describe them. Suffice it to say that they gave us the technology that made our brief, otherwise tedious existence in this universe worth living. We’ve compiled here a list of 25 ICs that we think deserve the best spot on the mantelpiece of the house that Jack Kilby and Robert Noyce built. Some have become enduring objects of worship among the chiperati: the Signetics 555 timer, for example. Others, such as the Fairchild 741 operational amplifier, became textbook design examples. Some, like Microchip Technology’s PIC microcontrollers, have sold billions, and are still doing so. A precious few, like Toshiba’s flash memory, created whole new markets. -

Professor Won Woo Ro, School of Electrical and Electronic Engineering Yonsei University The 1st Microprocessor The Intel® 4004 microprocessor, introduced in November 1971 An electronics revolution that changed our world. There were no customer‐ programmable microprocessors on the market before the 4004. It propelled software into the limelight as a key player in the world of digital electronics design. 4004 Microprocessor Display at New Intel Museum A Japanese calculator maker (Busicom) asked to design: A set of 12 custom logic chips for a line of programmable calculators. Marcian E. "Ted" Hoff Recognized the integrated circuit technology (of the day) had advanced enough to build a single chip, general purpose computer. Federico Faggin to turn Hoff's vision into a silicon reality. (In less than one year, Faggin and his team delivered the 4004, which was introduced in November, 1971.) The world's first microprocessor application was this Busicom calculator. (sold about 100,000 calculators.) Measuring 1/8 inch wide by 1/6 inch long, consisting of 2,300 transistors, Intel’s 4004 microprocessor had as much computing power as the first electronic computer, ENIAC. 2 inch 4004 and 12 inch Core™2 Duo wafer ENIAC, built in 1946, filled 3000‐cubic‐ feet of space and contained 18,000 vacuum tubes. The 4004 microprocessor could execute 60,000 operations per second Running frequency: 108 KHz Founders wanted to name their new company Moore Noyce. However the name sounds very much similar to “more noise”. "Only the paranoid survive". Moore received a B.S. degree in Chemistry from the University of California, Berkeley in 1950 and a Ph.D. -

Chapter 3 Microprocessors in the 1970's The creation of the transistor in 1947 and the development of the integrated circuit in 1958/59, is the technology that formed the basis for the microprocessor. Initially the technology only enabled a restricted number of components on a single chip. However this changed significantly in the following years. The technology evolved from Small Scale Integration (SSI) in the early 1960's to Medium Scale Integration (MSI) with a few hundred components in the mid 1960's. By the late 1960's LSI (Large Scale Integration) chips with thousands of components had occurred. This rapid increase in the number of components in an integrated circuit led to what became known as Moore’s Law. The concept of this law was described by Gordon Moore in an article entitled “Cramming More Components Onto Integrated Circuits” in the April 1965 issue of Electronics magazine [338]. -

Programmable Digital Microcircuits - a Survey with Examples of Use
- 237 - PROGRAMMABLE DIGITAL MICROCIRCUITS - A SURVEY WITH EXAMPLES OF USE C. Verkerk CERN, Geneva, Switzerland 1. Introduction For most readers the title of these lecture notes will evoke microprocessors. The fixed instruction set microprocessors are however not the only programmable digital mi• crocircuits and, although a number of pages will be dedicated to them, the aim of these notes is also to draw attention to other useful microcircuits. A complete survey of programmable circuits would fill several books and a selection had therefore to be made. The choice has rather been to treat a variety of devices than to give an in- depth treatment of a particular circuit. The selected devices have all found useful ap• plications in high-energy physics, or hold promise for future use. The microprocessor is very young : just over eleven years. An advertisement, an• nouncing a new era of integrated electronics, and which appeared in the November 15, 1971 issue of Electronics News, is generally considered its birth-certificate. The adver• tisement was for the Intel 4004 and its three support chips. The history leading to this announcement merits to be recalled. Intel, then a very young company, was working on the design of a chip-set for a high-performance calculator, for and in collaboration with a Japanese firm, Busicom. One of the Intel engineers found the Busicom design of 9 different chips too complicated and tried to find a more general and programmable solu• tion. His design, the 4004 microprocessor, was finally adapted by Busicom, and after further négociation, Intel acquired marketing rights for its new invention. -
