HSIC versus USB
A look at the advantages of HSIC over USB and the connection procedures that are involvedAndrew Rogers, Microchip Technology Inc.The high-speed inter-chip (HSIC) interface is becoming more popular due to its notable advantages over USB for hard-wired inter-chip applications. The interface is a two signal, source synchronous interface that can provide USB high-speed data at 480Mbit/s. The data transfers are 100% host driver compatible with traditional USB topologies. Full-speed (FS) and low-speed (LS) are not supported by the format, ... more
Pushing the Boundaries of Hall Effect Technology
Raising the benchmark for current measurement accuracy over a wide temperature rangeWhatever your application, intelligent power control optimises the use of electricity and ensures smooth control of equipment. For instance in machine tools, the current flow increases abruptly when the tool starts working on the part to be machined. The better and faster the feedback signal, the smoother the control of equipment operation. Intelligent power control is also a way of optimising the use of electricity. Upgrading variable speed ... more
Microchip Technology: Easy conversion - A look at how to implement an analogue-to-digital conversion in a low bandwidth application
Mark Pallones, Mike GomezImplementing an analogue-to-digital conversion in a circuit is one of the most common tasks facing designers and one that can be done in various ways. But for many simple and low bandwidth applications, such as a DC voltmeter for example, the goal is to keep the cost of the implementation low but still obtain a high resolution for the analogue-to-digital conversion.A simplified schematic of such a circuit is shown in Fig. 1. There are two input ... more
The initiative for establishing a public dialogue on the sustainable use of energy in South East Europe was launched by the members of the network of schools for political studies in South East Europe, under auspices of the Council of Europe, with the support of German International Cooperation and its Open Regional Fund for Energy Efficiency (GIZ-ORF-EE) and Visegrad International Fund.The Initiative was taken by the Belgrade Fund for Political Excellence (Serbia), School for Democratic Leadership (Montenegro) and Academy ... more
Lucio di Jasio, Microchip Technology: Core wars. What’s so important about the core anyway?
Lucio di Jasio, Microchip TechnologyThe availability of ever-smaller geometry CMOS processes has, in recent years, meant that manufacturers have been promoting 32-bit microcontrollers into segments which have previously been the domain of the 8-bit architecture. Encouraged by the strong campaigns mounted by ARM, some microcontroller manufacturers appear to have the 8-bit market clearly in their sights and have dedicated their entire portfolio to a 32-bit offering. This article looks at the rationale behind these choices, and the true impact ... more
Solar-Powered LED Lighting Power-Conversion Techniques
Stephen Stella, Microchip Technology Inc.Performance improvements in Light-Emitting Diodes (LEDs) and photovoltaic solar cells due to developments in technology improve the performance of the end-application. In applications that employ both of these core technologies in combination, such as solar-powered lighting, there is the potential to deliver substantial end-application performance improvement. For example, it’s possible to reduce the solar-cell area as higher-efficiency solar cells convert more of the Sun’s energy into electricity and the high-efficiency LEDs run longer and brighter ... more
Energy Market South East Europe 2014 conference in Pristina
Energy Market South East Europe 2014 regional conference was held between 18 and 19 September in Pristina, Kosovo. The organizers of the local consulting company Evroenergie, a subsidiary of the Energieweit (Germany) provided a platform for exchange of information and best practices aimed at decision makers in the energy industry and politics. Among the main topics were the challenges in the implementation of EU requirements, the potential of renewable energies in the Balkans and investment opportunities respectively on implemented ... more

The combination of 4G and IPv6 will bring about a new world of smarter M2M communicationRamanuja Konreddy, Microchip Technology Inc.The internet has already revolutionised the way in which people communicate with each other and now it is ready to enable another revolution: the proliferation of smart communication between machines.The technologies which will introduce smart machine-to-machine (M2M) communication are the high-speed 4G wireless standard and Internet Protocol version 6 (IPv6). Together, these technologies will enable designers to create a world ... more
Enabling a New Generation
The latest addition to Microchip’s PIC32 family increases performance, integration and connectivity.Bill Hutchings, Microchip Technolgy If there is one characteristic that all modern devices strive to demonstrate - irrespective of the end-application - it is responsiveness. The ability to react ’immediately’ is, of course, an illusion, sustained by the speed with which the microprocessor can respond to an event. Improving the response time of a microprocessor is often closely influenced by the software it executes, however the underlying metric ... more
Finding the right size Microcontroller
Keith CurtisMicrochip Technology Inc.The choice of which Microcontroller to use is made at the start of an embedded-control project. The options are to select an 8-bit, 16-bit or 32-bit MCU and either start from a low-cost micro and migrate up, or downsize from a high end micro.There are no hard and fast rules: a number of factors will influence the decision including the level of control and processing power the project will require, the power limitations... the list is almost ... more
