Events Span from June to August in US, Europe and India to Highlight Innovative Products and Technology

ALISO VIEJO, Calif., May 21, 2015 — (PRNewswire) — Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today announced it will be hosting a one-day Space Forum in five U.S. and international locations during June and August 2015. Microsemi's technical experts, along with the company's partners, will present today's leading space-related products, capabilities, technology roadmaps and solutions, including the newly introduced RTG4™ radiation-tolerant field programmable gate arrays (FPGAs) and the LX7730 telemetry controller, as well as a variety of its radiation-hardened DC-to-DC converters, precision time and frequency solutions, linear and point of load (POL) hybrids, custom hybrid solutions and radiation-hardened discretes―including the broadest portfolio of JANS Class diodes and bipolar transistor products.

"As part of our ongoing commitment to the space industry, this must-attend event is a unique opportunity to see Microsemi's roadmap for radiation-mitigated components and systems, and to explore in depth the technical details of Microsemi's latest RH and RT products," said Jim Aralis, chief technology officer and vice president of advanced development at Microsemi. "As Space Forum continues to gain in popularity with record-breaking attendance, we are pleased to offer this event in multiple regions this year and cater to the growing demand for our space expertise."

Microsemi's Space Forum is specifically designed for space industry system-level architects, research and development engineers, design and component engineers, and other space industry professionals seeking the latest innovations in this unique market. Each one-day event will be presented in two highly educational and informative tracks: Digital and Timing Track, and Mixed Signal and Power Track. In addition, Microsemi system architects and application engineers will discuss space system-level challenges and potential solutions.

The regional Space Forums will take place as follows:

Microsemi and its partners will focus on a number of topics, including:

• Detailed technical review of its new RTG4 high-speed radiation-tolerant Flash-based FPGAs
• New radiation-tolerant LX7730 telemetry controller integrated circuit (IC) providing key functions for sensor monitoring, attitude and orbit control and payload control
• Space-qualified crystal oscillators providing accurate frequency and time required for timing, radar and communication functions
• Updates on Microsemi's range of complementary radiation-tolerant power solutions including DC-DC converters, relays, hybrid and discrete technology
• SpaceWire and SpaceFibre (presented by STAR-Dundee)
• Building high reliability into Microsemi designs, the Synplify way (presented by Synopsys)
• A high-efficiency serial interface protocol–ESIstream (presented by e2v at Space Forum U.S. and Europe)
• Fault tolerant LEON3 processor and SpaceWire router standard products (presented by Cobham Gaisler at Space Forum Europe)

Microsemi's Space Forum is open to the company's customers, as well as other space industry architects and engineers. Press inquiries can be accommodated prior to or following the event.
