Microsemi Corporation carved a distinct and essential niche in the global semiconductor landscape by specializing in components renowned for their robustness and dependability in the harshest environments. Unlike mainstream consumer chipmakers, Microsemi's core mission centered on serving markets where failure was not an option.

Technology and Product Portfolio:
Microsemi's expertise spanned several key areas:

• Radiation-Hardened & High-Reliability Technology: Chips designed to withstand extreme conditions like space radiation, high temperatures, and intense vibration.

• FPGAs & SoCs: Field-Programmable Gate Arrays and System-on-Chip solutions, particularly known for their low-power Actel? FPGAs and radiation-tolerant offerings.

• Power Management: Highly efficient power conversion, management, and protection products.

• RF & Microwave Solutions: Components for communication, radar, and signal processing.

• Timing & Synchronization: Precision clocks and oscillators critical for network infrastructure and aerospace systems.

• Discrete Components: High-performance diodes, MOSFETs, and thyristors.

Target Markets:
Microsemi's components were vital to industries demanding unwavering performance:

• Aerospace & Defense: Avionics, satellites, missiles, secure communications.

• Industrial: Factory automation, medical equipment, power generation, transportation.

• Communications: Infrastructure equipment for telecom and data centers requiring precise timing and power efficiency.

Legacy and Acquisition:
Through strategic acquisitions (including Actel, Vitesse Semiconductor, PMC-Sierra, and others), Microsemi significantly expanded its product breadth and technological depth, becoming a major consolidator in the high-reliability semiconductor space. Its reputation for quality, stringent manufacturing standards, and deep certifications made it a trusted partner for demanding applications globally.

In May 2018, Microsemi was acquired by Microchip Technology Inc. for approximately $10.15 billion. This acquisition significantly bolstered Microchip's portfolio in aerospace, defense, communications, and data center markets, absorbing Microsemi's valuable technology, products, and expertise into its broader operations. While the Microsemi brand name is retired, its legacy of innovation in high-reliability semiconductors lives on within Microchip.
