Higher Level of Reliability Assurance Ideal for Aerospace Applications Requiring Screening Level Beyond Industry Standard MIL-STD-883 Class B

ALISO VIEJO, Calif., Nov. 29, 2012 — (PRNewswire) — �Microsemi Corporation (Nasdaq: MSCC), a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today introduced the addition of the Extended Flow (E Flow) to its RT ProASIC®3 field programmable gate array (FPGA) device family, providing additional screening options and a higher level of reliability assurance required in many critical space applications.

The RT ProASIC3 FPGA is the first single-chip flash FPGA of its kind to offer reprogrammability while requiring no additional code storage or mitigation for radiation-induced configuration upsets, unlike SRAM FPGAs. Microsemi's E Flow offers additional processing steps for space applications requiring a screening level beyond the industry standard MIL-STD-883 Class B.

The company conducts additional factory testing and screening, eliminating the need for customers to do so on their own. This in turn prevents schedule risk, saving customers both time and associated costs.

Microsemi has been providing solutions for demanding space applications for more than 55 years and currently has more than 150 fully qualified space products in its portfolio. The company's standard and customized space solutions include converters, FPGAs, customizable system-on-chip (cSoC) solutions, MOSFETS, rectifiers, switching diodes, transistors, DC-DC converters and zener diodes. 

Availability and Packaging
The RT ProASIC3 E Flow FPGAs are available in production now in various packages including its recently released ceramic quad flat pack (CQFP) CQ256 package. For more information on the E Flow, the RT ProASIC3 FPGA datasheet can be viewed at www.microsemi.com/soc/documents/RTPA3_DS.pdf.

Microsemi is a leader in space technologies and will be holding its next Space Forum in Los Angeles on Dec. 4, 2012. For more information, please visit www.microsemi.com/details/47-microsemi-space-forum.
