31st Annual Microprocessor Directory Field Guide
Welcome to the 31st annual EDN Microprocessor/Microcontroller Directory. The number of companies and devices the directory lists continues to grow and change. The size of this year's table of devices has grown more than 25% from last year's. Also, despite the fact that a number of companies have disappeared from the list, the number of companies participating in this year's directory has still grown by 10%. So what? Should this growth and change in the companies and devices the directory lists mean anything to you?
One thing to note is that this year's directory has experienced more company and product-line changes than the previous few years. One significant type of change is that more companies are publicly offering software-programmable processors. To clarify this fact, not every company that sells processor products decides to participate in the directory. One reason for not participating is that the companies are selling their processors only to specific customers and are not yet publicly offering those products. Some of the new companies participating in this year's directory have recently begun making their processors available to the engineering public.
Another type of change occurs when a company acquires another company or another company's product line. Some of the acquired product lines are no longer available in their current form, such as the MediaQ processors that Nvidia acquired or the Triscend products that Arm acquired. Those architectures and technologies may publicly resurface in the next year as different products. The recent creation of Freescale, a spinoff of Motorola, is similar to last year's spinoff of Renesas from Hitachi and Mitsubishi; these types of spinoffs allow the new companies to better focus on being more successfully competitive with their products.
The growth in the size and company-participation rate in the directory suggests that these changes are not an industry consolidation but rather are consistent with a budding or expected resurgence in embedded-design starts. This directory includes only software-programmable microcontrollers and microprocessors, including processor cores and programmable-logic devices with embedded-processor cores. The directory does not include DSPs; EDN lists DSPs in the annual DSP directory, which it publishes six months out of phase with this one.
As for the directory contents itself, this print version contains an alphabetical company-and-product summary to give you a high-level overview of this year's participating companies, their products, and any product or development-tool highlights from the last year. You can access the tables exclusively below, as a set of PDF files.
We welcome your feedback about the directory, because it can help us to make the directory more useful to you. Please let us know what types of information, such as development tools and third-party-support cross-indexing for each device, you'd like the directory to include. Send your comments to email@example.com. If this directory helps you choose a processor, please let the vendor know how you found its part. If you cannot find your favorite processor company or devices, please notify both that company and EDN that you missed reading about them in the directory.
You can print the following tables in two ways for the most effectiveness. If you have duplex (two-sided) printing, the file will position the two-page-wide tables so that each side prints opposite each other. If you do not have duplex printing, you can use the print properties to print two pages per sheet, if you skip the first (blank) page. Doing so will print both halves of the table opposite each other on the same page; however, the print will be smaller.

These 8-bit microcontrollers target embedded control and communication applications in consumer electronics, home appliances, security systems, point-of-sale terminals, PC peripherals, and industrial and automotive applications. Zilog also offers the stand-alone, general-purpose Z80 microprocessor with no integrated memory. Zilog's modular development tools and general-purpose boards include Zilog's ZTP TCP/IP software to support development using the Z8 Encore!, Z8Encore! XP, and eZ80Acclaim! devices.
