Microsemi

Microsemi is a semiconductor manufacturer that provides integrated circuits, system-on-chip devices, and related solutions for communications, aerospace and defense, industrial, and data center applications.

• Mixed-signal and RF semiconductors for communications, aerospace and defense, and industrial systems
• Field Programmable Gate Array (FPGA), SoC, and Application-Specific Integrated Circuit (ASIC) devices for embedded processing and hardware-based logic (semiconductor design)
• Power management, timing, and synchronization components for wired and wireless infrastructure (power and timing)
• Secure, reliability-focused components for avionics, military, and space systems (aerospace and defense electronics)
• Interface, storage, and connectivity solutions for enterprise, cloud, and data center equipment (data infrastructure)

More About Microsemi

Microsemi focuses on semiconductor and system-level solutions used by enterprises and institutions that operate communications networks, data centers, industrial systems, and aerospace and defense platforms. Its portfolio spans mixed-signal integrated circuits, field-programmable gate arrays (FPGAs), system-on-chip (SoC) devices, and application-specific integrated circuits (ASICs), along with analog, RF, power, timing, and connectivity components. These devices are typically integrated into routers, switches, base stations, storage arrays, industrial controllers, avionics systems, and other embedded platforms where reliability and long service lifetimes are required.

In networking and communications environments, Microsemi provides semiconductors for carrier Ethernet, optical transport, and packet-based timing. Its timing and synchronization components (timing and synchronization) support architectures based on IEEE timing standards and Precision Time Protocol (PTP), which are used to coordinate clocks across IP networks. Telecom and enterprise network equipment manufacturers use these parts for functions such as clock generation, jitter attenuation, and network time distribution in switches, routers, and radio access nodes.

For compute and storage infrastructure, Microsemi offers controller and interface devices (data infrastructure) that connect servers, solid-state drives, and hard disk drives to host systems. These solutions are used in enterprise storage arrays and cloud data centers to manage data paths, optimize throughput, and support redundancy schemes. Products in this category often align with storage interface standards such as Substation Automation System (SAS), Serial ATA (SATA), and PCI Express (PCIe), and are embedded on host bus adapters, Redundant Array of Independent Disks (RAID) controllers, or storage backplanes.

In aerospace and defense, Microsemi supplies secure and radiation-tolerant components (aerospace and defense electronics) for avionics, radar, communications, and space hardware. This includes programmable logic devices such as FPGAs and SoCs (programmable logic) as well as power and RF semiconductors that comply with military and space qualification standards. These components are selected for deterministic behavior and predictable failure modes, supporting system architects who must meet stringent certification and reliability requirements.

Industrial and automotive customers use Microsemi’s power management and mixed-signal devices (power and mixed-signal) for motor control, sensing, and embedded control units. These semiconductors support architectures where microcontrollers or programmable logic interface with sensors, actuators, and communication buses in factory automation, energy systems, and transportation equipment.

Across these solution areas, Microsemi positions its technology at the component and subsystem level rather than as full end-to-end platforms. Enterprise technical stakeholders typically engage with Microsemi through reference designs, evaluation boards, and detailed datasheets that specify electrical characteristics, protocol compliance, and environmental ratings. The company’s offerings map into marketplace categories such as programmable logic (FPGAs and SoCs), timing and synchronization, power management, RF and microwave components, storage and connectivity controllers, and aerospace and defense-grade semiconductors, supporting OEMs that design infrastructure, industrial, and mission-critical systems.
