Cover Story

EDN's 25th Annual
Microprocessor/Microcontroller Directory

Introduction

In one way or another, µPs play a role in almost every aspect of our lives—from toaster ovens to complex network-routing systems, from automobile-engine controllers to cellular phones, and from digital cameras to laser printers. Microprocessors are even replacing many, if not most, simple mechanical switches. Hence, to accommodate the growing need for µPs, the industry has grown rapidly in the 25 years since EDN delivered you the first Annual Microprocessor Directory.
