Embedded Forum at Electronica, a Theatre-Style Presentation Area Located in Hall A6, the Dedicated “Embedded Hall” VIEWPOINT Dear Reader, The electronica 2008, 23rd world´s leading trade fair for electronic com- ponents, systems, and applications is just a few weeks ahead and will take place from November 11th to 14th in the New Munich Fair Centre. To in- form you about this important event we created an electronica preview starting at page 12 where you will find all the information you need to plan your visit for example how to save money with your online registration. Please note that there are new opening times due to suggestions of exhibitors and visitors, too. Of special interest for you might be the Embedded Forum at electronica, a theatre-style presentation area located in Hall A6, the dedicated “Embedded Hall”. At the Embedded Forum ICC Media will stage a 4-day forum programme with half-hour presenta- tions about technical and market trends, products, solutions, and applications. The attendance of the Embedded Forum is free for all electronica visitors. You´ll find the programme starting at page 14 and can select the most interesting presentations for you. Saving energy – what also implies protecting the environment – is a big 32-bit MCU Solutions with issue today. Especially the manufacturers of appliances are looking for new ways saving as much energy as possible. In our cover story the Flexis integrated TFT / LCD Controller MCU are described. This is a family of compatible 8- and 32-bit from Atmel with ARM926EJ and AVR32 AP7 Core technology. microcontrollers which allows the designers to evaluate both options ® before deciding the best choice for a given application.

  • Familias De Microcontroladores
    INTRODUCCION Un microcontrolador es un circuito integrado tiene en su interior todas las características de un computador, es decir, programa y circuitos periféricos para CPU, RAM, una memoria de entrada y salida. Muy regularmente los microcontroladores poseen además convertidores análogo - digital, temporizadores, contadores y un sistema para permitir la comunicación en serie y en paralelo. Se pueden crear muchas aplicaciones con los microcontroladores. Estas aplicaciones de los microcontroladores son ilimitadas, entre ellas podemos mencionar: sistemas de alarmas, iluminación, paneles publicitarios, etc. Controles automáticos para la Industria en general. Entre ellos control de motores DC/AC y motores de paso a paso, control de máquinas, control de temperatura, tiempo; adquisición de datos mediante sensores, etc. HISTORIA El primer microprocesador fue el Intel 4004 de 4 bits, lanzado en 1971, seguido por el Intel 8008 y otros más capaces. Sin embargo, ambos procesadores requieren circuitos adicionales para implementar un sistema de trabajo, elevando el costo del sistema total. Los ingenieros de Texas Instruments Gary Boone y Michael Cochran lograron crear el primer microcontrolador, TMS 1000, en 1971; fue comercializado en 1974. Combina memoria ROM, memoria RAM, microprocesador y reloj en un chip y estaba destinada a los sistemas embebidos.2 Debido en parte a la existencia del TMS 1000,3 Intel desarrolló un sistema de ordenador en un chip optimizado para aplicaciones de control, el Intel 8048, que comenzó a comercializarse en 1977.3 Combina memoria RAM y ROM en el mismo chip y puede encontrarse en más de mil millones de teclados de compatible IBM PC, y otras numerosas aplicaciones. El en ese momento presidente de Intel, Luke J.

It soon of standardization of the on-chip debug and trace became clear that pure debuggers without trigger logic as well as a reduction in pincount without any and trace options were not adequate for developing performance loss. In order to take an active role PowerDebug complex embedded designs efficiently. The scope in the development of innovative debug and trace of on-chip debugging and trace interfaces has been technologies, Lauterbach has been participating enlarged gradually, enabling very complex test and in various international committees over the past PowerTrace analysis functions with today’s development tools. years: • Lauterbach has been a member of the Nexus 5001™ Forum ever since its foundation and was first to market with tools conforming to the PowerProbe NEXUS specification. • In the Test & Debug Working Group of the MIPI Alliance, Lauterbach has been involved in the Power- definition of interfaces as well as corresponding Integrator test and debug tools for mobile phones. • Lauterbach has been an active member of the IEEE P1149.7 Working Group for the definition of new JTAG standards ever since its foundation. In 2006 Lauterbach was able to significantly staff up its engineering departments, further strength- ening its leadership position in high performance development tools for a wide range of processor architectures.
