By Robert Cravotta, Technical Editor

Use the menus on the left to access a wealth of information on more than 70 vendors and hundreds of microprocessor and microcontroller devices and cores. Drill down by either company name or your target application. Either way, you'll find an overview of each vendor's activities, parametric tables detailing every vendor's complete product lineup (also listed to the left), and detailed descriptions of each processor family (augmented in many cases by an architectural block diagram). Continues below

Continued from above  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.

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 vendor list on the left shows the companies selling software-programmable processors and cores and provides an overview for each as well as identifies the latest developments over the previous year at each company. 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. You'll also find a listing of third-party-software-development companies.

The “Where are they now?” sidebar (below) helps you find companies that we no longer list, whether because they closed their doors, changed their focus (think National Semiconductor), another company acquired them, or they spun off into a different company.
