DSCs drive home appliances energy-savings
Appliance designers can now take advantage of the latest Digital Signal Controllers (DSCs), such as Microchip’s dsPIC33F motor-control family, to improve energy efficiency and cost savings in motor systemsJorge ZambadaMicrochip TechnologyGiven that motor-driven equipment, including motors, pumps and fans, can account for 64 percent of the electricity consumption, improvements to motor systems could result in dramatic savings in energy and cost. The Brushless DC (BLDC) motor is used in both consumer and industrial applications, owing to its compact size, controllability ... more

You have the power!
Deeply embedded applications can now enjoy leading edge processing power, thanks to 32bit developments in microcontrollers.Coming from a background of desktop applications, it would seem strange to consider using a processor that offers anything less than leading edge performance. For an engineer more entrenched in embedded applications, processing power has always been measured not just against the benefits it brings but by the resources it consumes.Within the embedded domain, the irresistible force that is ‘faster, smaller, cheaper’ has always been ... more

Most of the electronics producers have quality management systems applied – ISO 9000, ISO 16949. Up-to-date manufacturing technologies, high level of the production ranges and the ... more
The Power of Moving-Average Digital Filters
by Bonnie C. Baker, Microchip Technology Inc.Often, analogue-to-digital converter users employ averaging algorithms with their controller or processor on the output of several samples from the converter. A converted signal can be smoothed by using this technique (see Figure 1), and the effective resolution can be improved by reducing system noise.Smoothing converted dataThe smoothing effect on the converted data is implemented by acquiring multiple signals at a constant sample rate, averaging a predetermined group or number of the samples, and ... more
Taking the Strain out of Selecting Amplifiers for Gauge Applications
Kevin Tretter,Microchip Technology Inc.The world of data acquisition is extremely diverse, encompassing measurements of temperature, pressure, humidity, strain and a variety of other physical phenomenon. In addition, these measurements may be required under harsh conditions, such as extreme temperatures, centrifugal forces and electrically noisy environments. System designers must be diligent in not only selecting the correct sensor for their application, but also in designing appropriate signal conditioning to deal with these issues. This article will focus on the signal conditioning ... more

Bridging the Rails
Gaurang Kavaiya,Microchip Technology Inc.From the early days, the ‘mantra’ for the semiconductor industry has been “Smaller, Better, Faster and Cheaper”. The current Pocket PCs are more powerful than the first computer, which required a separate building. The way this goal has been achieved, so far, is to reduce the size of the individual transistor used to create the semiconductor device. This has an interesting side effect. As the transistor gets smaller, the operating voltage gets lower. The 5V power-supply rail ... more
Intelligent Power-Supply Design
Lucio Di Jasio, Microchip Technology Inc.Switch-Mode Power Supplies (SMPS) are traditionally implemented using a basic analogue control loop. Recently, advances in Digital Signal Controllers (DSCs) have enabled designs where full digital control schemes begin to become practical and economical. Still, early adopters of digital technology are expected to be at the high-end of the applications spectrum, where the benefits of full digital control are the most immediate. However, there are a large number of applications that can greatly benefit from ... more
8-bit MCUs Challenge the 4-bit Package and 32-bit Power
Lucio Di Jasio,Microchip Technology Inc.One of the basic rules of evolution is that adaptation is the key to survival and perhaps no other technology demonstrates this as well as the 8-bit microcontroller (MCU). Throughout its thirty-year history, the 8-bit MCU has undergone continual adaptation and, even today, is colonising slots which would once have been the exclusive territory of the more powerful 32-bit MCU or the smaller 4-bit MCU.Thirty years of 8-bit MCUsThe first single-chip 8-bit microprocessor was released by ... more
Techniques for measuring with non-linear sensors
Bonnie C. Baker, Microchip Technology Inc.A sensor with a non-linear output need not be difficult to deal with if all that is needed is coverage of a small portion of the output range. In such a case, it is possible to set up a simple, piecewise linearisation algorithm in a microcontroller or microprocessor. If a wider part of the output range is required, analogue linearisation circuits can be used. For example, a resistor in series or parallel with a (non-linear) ... more

A digital solution to analogue oscillator problems
Bonnie C. Baker, Microchip Technology Inc.A designer presented with the task of producing a 100Hz sine-wave signal will probably consult analogue cookbooks and/or the web for a quick and suitable solution. This can be a good way to start, but it ignores another, potentially powerful, solution. Designers are always under pressure to produce their designs quickly, but before leaping to use an analogue circuit, it may be beneficial to consider using a digital engine, such as a microcontroller or microprocessor.A ... more
8-Bit Microcontrollers Extend their Reach
Steve Sanghi, Chairman of the Board, CEO and President Microchip Technology Inc.The Sophisticated ConsumerAccording to one study, the typical consumer touches almost 100 embedded microcontrollers (MCUs) every day before noon. Recent surveys have also shown that the mobile phone is the device that most consumers feel that they could least afford to lose. Thanks to mobile computing and communications, the world is smaller, response times are shorter and even the most non-technical person is aware of the presence of computers ... more
Wind Energy: Technologies and Trends in Wind Power Plants Development
The development of technologically and cost effective solutions for the wind energy conversion into electrical energy has been one of the greatest technical challenges in the last decades. The idea of using wind energy for the generation of electricity could rightly be regarded as the logical continuation of its utilization for centuries as the driving power for various types of equipment, among which wind mills undoubtedly have greatest popularity. Despite the relatively short history of wind plants . the first ... more
