Welcome to the 35th annual EDN microprocessor/ microcontroller directory. Once again, the companies and devices in the directory continue to evolve and grow in number. The company roster and product listings are testaments to the variety of processors available and the tremendous variation among requirements, features, and types of applications for which designers are using microprocessors and microcontrollers. EDN is constantly uncovering companies that previous editions of the directory did not list. If you notice a company that we omitted, please let it and us know that you missed it and would like to see it in the next update of the directory.
The print version of this directory is but a small fraction of the entire directory, which stresses what is new over the last year for each company. Visiting the Web version of these pages at www.edn.com/ microdirectory will allow you to directly access detailed information on each of the companies listed here. The Web version has taken on more importance as the company roster continues to expand the material of hundreds of pages. We also list the companies selling software-programmable processors and cores and provide an overview for each as well as identify the latest developments over the previous year at each company.
This year’s online version makes it easier to find the third-party-software-development companies by placing them in a companion directory that is cross-linked on the main pages of each listing. This directory aims to provide designers and system architects enough visibility into processor options to quickly narrow the list of candidate processors for each project. The expanded online section presents each processor, with detailed information and block diagrams. The directory uses a common taxonomy for describing and categorizing target applications that helps you to quickly find and compare competing processors for your projects. The Web material has more details on the common application taxonomy so that you can comment on it, and we can refine it as appropriate.
The “Where are they now?” sidebar on the Web helps you find companies that we no longer list, whether because they closed their doors, they changed their focus (for example National Semiconductor), another company acquired them, or they spun off into a different company. As always, the Web site duplicates and greatly expands upon the material you find in the print version.
If this directory helps you find or choose a device or core, please let the vendor know how you found its part. Help us continue to improve the directory by visiting us at www.edn.com/microdirectory or by sending your comments and feedback to microdirectory@edn.com.
