EDN's 24th Annual
Microprocessor/Microcontroller Directory

MARKUS LEVY, TECHNICAL EDITOR

This directory is once again overflowing with useful information. And, as the number of µP and µC families and products continues to grow, the Web provides the best way for this directory to grow and provide you with the most up-to-date information. So, if you don't find what you need within the following pages, check out our site: www.ednmag.com.

Twenty-four years! That's how long ago EDN provided you with its first comprehensive µP directory. (Most of you weren't even born yet, right?) Well, if you compare the 1973 and 1997 versions of the directory, you'll find that the biggest change is that we now devote almost 60 pages to this incredible information source.

As in the past, the directory comprises architectural and product sections. The architectural section describes the composition of the processor cores, including register and instruction sets, pipeline stages, and power-management features. The architectural section adds information that describes the µP family's development tools and special on- and off-chip peripherals. The product sections, in tabular format, provide device-specific information, such as operating frequency, peripheral sets, and prices. You'll also find details about a few devices that exemplify the corresponding processor families in the architectural section.

Many readers tell us that they keep EDN's µP/µC directory around for a year and use it as a key reference for their new designs. For these readers, and all of EDN's readers, we have put a permanent link to the directory right on EDN's home page. Just click, and you'll have access to this directory. And as an added bonus, the Web-site version of the directory contains an expanding database of processors that will help you find the device you're seeking. Send your comments to markuslevy@aol.com so that I can continue to make this your directory.
