Zilog Announces Z8051 MCU Development Tools   
Featuring a Wide Array of Industry-Standard 8051-Based  Solutions

Milpitas, CA and Biel, Switzerland, February 7, 2013 – Zilog, a wholly-owned subsidiary of IXYS Corporation (NASDAQ:IXYS) and a pioneer supplier of application-specific, embedded microcontroller (MCU) system-on-chip (SoC) solutions for industrial, power management and consumer applications, today introduced Version 2.1 of its Z8051 MCU Development Tools.

This new version of Zilog’s Z8051 toolset now offers seamless integration of the Keil^® debugger with Zilog’s On-Chip Debugger, allowing users of the Keil^® C51 tool to work in the Keil^® environment without switching between the Keil^® compiler and Zilog’s external OCD software.

Zilog’s Z8051 Software and Documentation package provides applications and documentation support for the Z8051 microcontroller, the Z8051 On-Chip Debugger and In-System Programmer, and the Z8051 development boards. It includes sample applications, device drivers, and distribution of free open-source small device C Compiler (SDCC) software development tools and header files. Zilog’s Z8051 microcontrollers and their related development toolsets are described in Zilog’s Z8051 product specifications, user guides and other required documentation. This documentation is packaged with the Z8051 Tools version 2.1 as a single file which is available for free from the Zilog Store.

Zilog’s Z8051 MCU products provide flexible and cost-effective solutions to a variety of embedded control applications. Development software is available from numerous third-party support centers, which often means no change to the development environments that design engineers are already using for their 8051 platforms.

“Zilog, as a part of IXYS, maintains a continuing commitment to supporting our customers with a long product life cycle, especially in power management, where IXYS has been growing worldwide. With the growth of digital power management in energy-efficient products for clean energy generation, automation, appliances, automotive, lighting and telecommunication, we believe that offering the popular Z8051 MCU allows us to accelerate the adoption of our MCU solutions in these markets,” said Steve Darrough, Zilog’s VP of Marketing. “The world of IXYS, especially for our customers, now includes power semiconductors, analog ICs, mixed-signal ICs, SSRs, MCUs and RF devices to complete a synergy of system design possibilities like no other semiconductor company.”

Zilog’s Z8051 products and development kits are now available for customers that place orders through Zilog’s distribution or representatives. For more information, visit www.zilog.com.
