2020 Annual Report 2020 Annual Report Dear Fellow Stockholders, At this time last year, we were just beginning to grasp the challenges that the COVID-19 pandemic would bring to our industry and to our lives. In the year since, we have moved to remote work arrangements for most of our employees, halted nearly all travel, customer visits and in-person events, weathered business interruptions at several of our suppliers, and experienced a sharp decline in demand followed by a steep recovery that is now straining supply chains across our industry. As of this writing, much of our workforce continues to work remotely as we prioritize the health of our employees and comply with local regulations. I look forward to a full return to our offices as soon as we are able to do so safely, but in the meantime I continue to be impressed with the creativity and dedication of our employees, who have not just kept our business on track but also delivered the best results in our history in 2020. Our approach to managing through the past year reflects the long-term, sustainable orientation that has always been a cornerstone of our success. While some of our industry peers reduced headcount or cut salaries in the early stages of the pandemic, we continued to invest in our people, giving normal salary raises, maintaining our generous health benefits, and expanding our workforce by four percent during the year, with the largest increase coming in research and development. (In fact, we hired a number of highly capable people let go by industry peers in the early stages of the pandemic.) We also invested in production capacity and infrastructure, spending more than $70 million in capital last year, including nearly $15 million on the construction of new facilities for our European operations and updates to our San José headquarters. We plan to invest $12-$15 million more in 2021 to complete our European facilities and to expand our San José solar array, roughly doubling our generating capacity. We also built inventory as demand softened in the early stages of the pandemic, rising to 178 days on hand at the end of the June quarter. Building inventory is something we can afford, knowing that our products have long shelf lives and are fungible across applications and customers. It brings stability to our foundry relationships, helping to preserve our capacity, and enables us to satisfy customers when demand recovers, as has happened over the past several months. Shortages of semiconductor products have been a major news story of late, affecting the supply of appliances, cars, game consoles, TVs and many other end products. In our case, inventories at our distributors are lower than normal and lead times have extended for some of our newer products, but we’ve thus far been able to keep most customers’ production lines running thanks to our timely capacity additions and our decision to build inventory last year amid falling demand. Our bias toward long-term thinking is most evident in our approach to R&D. About a decade ago we increased our R&D spending with an eye toward expanding our addressable market and developing more disruptive technologies. We did so knowing that the fruits of these efforts would take many years to be fully realized, and I am excited about the years ahead precisely because we are now beginning to see the pay-off from these long-term investments. One example is our gallium- nitride, or GaN, technology. We were the first company to ship high-voltage GaN products in high volume when we introduced GaN-based InnoSwitch™ products in 2018, and GaN-based products are now contributing meaningful revenues, with about $10M in sales in 2020—a number that we expect to double or perhaps triple in 2021. Similarly, we began development of our BridgeSwitch™ motor-driver ICs many years ago, and will see our first meaningful revenues in 2021. A few years ago we also began developing products for the automotive market, where significant revenues are likely still several years away but where the opportunity is substantial. High-voltage is pervasive in electric vehicles (EVs), not just in the drivetrain but also charging and, in next-generation vehicles, power supplies that will drive many of the subsystems in the car from the main battery. In 2020 we qualified versions of our LinkSwitch™ and InnoSwitch products for automotive use, and we continue to work closely with automakers on gate-driver products for EV drivetrains. The investments we have made will enable us to continue benefiting from many of the secular trends that helped drive our strong results in 2020. While revenues for the analog semiconductor industry grew just three percent for the year,1 our revenues grew 16 percent, with growth in all four end-market categories. The consumer category, our largest end market entering the year, grew about ten percent and finished strong, up nearly 20 percent year-over-year in the fourth quarter. Appliances were the main source of growth, reflecting robust end-market demand and share gains at a broad range of customers, as well as rising semiconductor content. Content growth is an important secular trend in appliances driven by the proliferation of new features such as network connectivity, LED lighting and advanced displays, even as tighter energy- efficiency standards challenge designers to do more with less power, which in turn drives even greater need for our products. 1According to World Semiconductor Trade Statistics In the industrial category, demand for our high-power gate-driver products was constrained last year by pandemic-driven delays in infrastructure projects. However, lower revenues in high power were offset by growth in home-and-building automation, battery-operated tools, and broad-based industrial applications, resulting in low-single-digit growth for the overall category. Going forward, we expect our industrial business to benefit from secular trends such as renewable energy, high-voltage DC transmission, electrification of transportation and tools, smart homes and buildings, and fixed USB charging receptacles. The communications category grew more than 30 percent for the year, while the smaller computer category grew even faster, up nearly 50 percent. Some of this growth, particularly in the computer category, was the result of the work-from- home and learn-from-home trends, which drove strong demand for PCs, tablets and monitors. Another key factor—one sure to endure beyond the pandemic—is the rapid adoption of advanced chargers for smartphones, tablets and notebooks. Power Integrations has demonstrated a commanding lead in terms of technology and product design for advanced chargers, and that advantage is now translating into rapid growth in market share and revenue. Not long ago, cellphone chargers were essentially commodities, and cost was the only variable that mattered. Today, OEMs are thinking strategically about chargers, either as a value-added feature or a revenue-generating accessory, and a wave of third-party after-market brands has emerged as well. We’ve seen this change coming for quite some time, and we were ready for it thanks to the R&D investments we’ve made in technologies like GaN and revolutionary products like InnoSwitch. In fact, while InnoSwitch ICs are used in a broad range of applications, their success in the high-volume smartphone market has made them the highest-selling power-supply ICs in the world, with well over a billion units shipped in the six years since their introduction. The adoption of advanced chargers for smartphones accelerated last year and shows no signs of slowing. Even as 5G phones demand higher-power chargers due to their larger batteries, many OEMs are pushing power levels even higher to offer much faster charging as a way to differentiate their products. Meanwhile, we are seeing an unprecedented wave of innovation in charger design, including an increasing number of chargers capable of powering two or more devices, and a robust pipeline of designs with our GaN products. That includes our GaN-based InnoSwitch products as well as our MinE- CAP™ ICs, which use GaN technology to reduce the size of chargers by enabling smaller input capacitors. Thanks in large part to our record revenues in 2020, we generated $126 million in cash flow from operations, and further strengthened our balance sheet, ending the year with $449 million in cash and investments. Reflecting our strong cash flow and healthy balance sheet, our board of directors has increased our quarterly dividend 37% over the past four quarters, with the payout increasing to 13 cents per share beginning in the March quarter. We also implemented a stock dividend in August 2020, which effectively resulted in a two-for-one stock split. Our strong financial position gives us ample flexibility to continue investing in our future growth while returning cash to stockholders in the years ahead. Thank you for your continued support of our company—I look forward to reporting on our progress in the year ahead.

A given ISA may be implemented with different microarchitectures.[1] Implementations might vary due to different goals of a given design or due to shifts in technology.[2] Computer architecture is the combination of microarchitecture and instruction set design. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the execution model, processor registers, address and data formats among other things. The Intel Core microarchitecture microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less detailed) diagrams that describe the interconnections of the various microarchitectural elements of the machine, which may be everything from single gates and registers, to complete arithmetic logic units (ALU)s and even larger elements.

THIS SITE WAS ESTABLISHED TO COLLECT AND PRESENT INFORMATION AND STORIES RELATED TO FAIRCHILD SEMICONDUCTOR AS PART OF THE OCTOBER 2007 CELEBRATION OF THE FIFTIETH ANNIVERSARY OF THE FOUNDING OF THE COMPANY. IF YOU HAVE ANY CORRECTIONS OR ADDITIONAL INFORMATION TO CONTRIBUTE PLEASE CONTACT THE FACILITATORS LISTED BELOW. Overview Founded in 1957 in a building now designated as California Historical Landmark # 1000 in Palo Alto, California by eight young engineers and scientists from Shockley Semiconductor Laboratories, Fairchild Semiconductor Corporation pioneered new products and technologies together with an entrepreneurial style and manufacturing and marketing techniques that reshaped Silicon Valley and the world-wide industry. The Planar process invented in 1959 revolutionized the production of semiconductor devices and enables the manufacture of today's billion transistor microprocessor and memory chips. Funded by and later acquired as a division of Fairchild Camera and Instrument Corporation of Syosset, New York, Fairchild was the first manufacturer to introduce high-frequency silicon transistors and practical monolithic integrated circuits to the market. At the peak of its influence in the mid-1960s, the division was one of the world’s largest producers of silicon transistors and controlled over 30 percent of the market for ICs. Director of Research and Development, Gordon Moore observed in 1965 that device complexity was increasing at a consistent rate and predicted that this would continue into the future. “Moore’s Law,” as it became known, created a yardstick against which companies have measured their technology progress for over 40 years.

  • Ic 555 Timer Applications Pdf
    Ic 555 timer applications pdf Continue The 555 timer is a linear IC that works as a monosttable multivisibrator, astable multivisual, Schmitt trigger, generator function with the output of wave-shaped shapes (such as square waves), time delay pulses, and pulse-width modulation (PWM) and modulation of pulse position (PPM) circuits have various electronic control applications. Each year, millions of 555 IC units are manufactured by various manufacturers to meet industrial and commercial applications. The 555 IC was designed by Hans R. Camenzind in 1971 while working for Signetics Corporation. In the early 1970s, Signetics Corporation released 555 timers in the trading names SE555 timer and NE555 timer for military and commercial applications, respectively. The 555 Timer is an accurate synchronization circuit that can produce pulses of precise and very stable time delays from microseconds to hours. It is mainly used in practical circuits like flip-flops in monosteb, bistable, and astable shapes. From its applications, it is known as an ic time machine. The 555 IC is used mainly for timer functions in commercial electronic circuits. In timer applications, the duration or duration of output pulses is determined by charging and unloading the capacitor through resistors connected externally to the 555 timer. The output cycle is governed by components of the R and C. 555 timers synchronization scheme to work on power voltages from 5 B to 18 B. They are compatible with the logical schemes TTL (Transistor-Transistor Logic) and CMOS (Additional Metal Oxide Semiconductor). Packages from 555 TimerThe 555 ICs are available in a standard double online package (DIP), 8-pin mini DIP or 14-pin DIP.

  • The Era of Microprocessor
    Excel Journal of Engineering Technology and Management Science (An International Multidisciplinary Journal) Vol. I No. 4 January - June 2013-14 (Online) ISSN 2277-3339 THE ERA OF MICROPROCESSOR * Mr. Pritaj P. Mhaske, Shreeyash Polytechnic, Satara Tanda, Aurangabad. THE ERA OF MICROPROCESSOR WHAT IS A MICROPROCESSOR? A microprocessor incorporates the functions of a computer’s central processing unit (CPU) on a single integrated circuit(IC),or at most a few integrated circuits. It is a multipurpose, programmable device that accepts digital data as input , processes it according to instructions stored in its memory , and provides results as output . It is an example of sequential digital logic as it has internal memory. Microprocessors operate on numbers and symbols represented in the binary numeral system. The advent of low cost computers on integrated circuit has transformed modern society. General purpose microprocessor in personal computers are used for computation ,text editing multimedia display and communication over the internet .Many more microprocessor are part of embedded systems, providing digital control of a myriad of objects from appliances to automobiles to cellular phones and industrial process control. INTRODUCTION Intel introduced its 4 bit microprocessor 4004 in 1971 and its 8 bit microprocessor 8008 in 1972. This microprocessor could not survive as general purpose microprocessor due to their design and performance limitation. The launch of first general purpose 8 bit microprocessor 8080 in 1974 by Intel is considered to be the first major stepping stone towards development of advanced microprocessor. The microprocessor 8085 followed 8080, with few more added feature to its architecture which resulted in the functionally complete microprocessor.

  • Overview of Microprocessors
    C HAPTER – 1 OVERVIEW OF MICROPROCESSORS 1.1 GENERAL A microprocessor is one of the most exciting technological innovations in electronics since the appearance of the transistor in 1948. This wonder device has not only set in the process of revolutionizing the field of digital electronics, but it is also getting entry into almost every sphere of human life. Applications of microprocessors range from the very sophisticated process controllers and supervisory control equipment to simple game machines and even toys. It is, therefore, imperative for every engineer, specially electronics engineer, to know about microprocessors. Every designer of electronic products needs to learn how to use microprocessors. Even if he has no immediate plans to use a microprocessor, he should have knowledge of the subject so that he can intelligently plan his future projects and can make sound engineering judgements when the time comes. The subject of microprocessors is overviewed here with the objective that a beginner gets to know what a microprocessor is, what it can do, how it fits in a system and gets an overall idea of the various components of such a system. Once he has understood signam of each component and its place in the system, he can go deeper into the working details and design of individual components without difficulty. 1.2 WHAT IS A MICROCOMPUTER? To an engineer who is familiar with mainframe and mini computers, a microcomputer is simply a less powerful mini computer. Microcomputers have smaller instruction sets and are slower than mini computers, but then they are far less expensive and smaller too.

  • 555 Timer Ic.Pdf
    555 timer IC 1 555 timer IC The 555 Timer IC is an integrated circuit (chip) implementing a variety of timer and multivibrator applications. The IC was designed by Hans R. Camenzind in 1970 and brought to market in 1971 by Signetics (later acquired by Philips). The original name was the SE555 (metal can)/NE555 (plastic DIP) and the part was described as "The IC Time Machine".[1] It has been claimed that the 555 gets its name from the three 5 kΩ resistors used in typical early implementations,[2] but Hans Camenzind has stated that the number was arbitrary.[3] The part is still in wide use, thanks to its ease of use, low price and good stability. As of 2003, it is estimated that 1 billion units are NE555 from Signetics in dual-in-line package manufactured every year.[3] Depending on the manufacturer, the standard 555 package includes over 20 transistors, 2 diodes and 15 resistors on a silicon chip installed in an 8-pin mini dual-in-line package (DIP-8).[4] Variants available include the 556 (a 14-pin DIP combining two 555s on one chip), and the 558 (a 16-pin DIP combining four slightly modified 555s with DIS & THR connected internally, and TR falling edge sensitive instead of level sensitive). Ultra-low power versions of the 555 are also available, such as the 7555 and TLC555.[5] The 7555 requires slightly different wiring using Internal block diagram fewer external components and less power. The 555 has three operating modes: • Monostable mode: in this mode, the 555 functions as a "one-shot".
