- Microsemi Corporation (Nasdaq: MSCC), a provider of semiconductor and system solutions for aerospace and defense, communications, data center, and industrial markets, was acquired by Microchip Technology Incorporated in May 2018 and operates as a subsidiary, with Microchip continuing to offer Microsemi's product portfolio. The company designs, manufactures, and markets high-performance, radiation-hardened analog mixed-signal integrated circuits; field programmable gate arrays (FPGAs) and system-on-chip (SoC) solutions including flash-based FPGAs from 5K to 150KLUTs, space-grade FPGAs, and PolarFire mid-range FPGAs; power management products such as switching and linear voltage regulators, electronic fuses, and space-grade power supplies; timing and synchronization devices including atomic clocks, time servers, precision time protocol grandmasters, and frequency synthesizers; voice processing devices and SLICs; RF solutions comprising transceivers, MMICs, PIN diodes, and gallium nitride transistors; discrete components and power discretes like SiC diodes, MOSFETs, IGBTs, BJTs, diodes, and JFETs; Ethernet solutions and Power-over-Ethernet (PoE) ICs, midspans, injectors, and switches; storage solutions including RAID controllers, SAS/SATA host adapters, NVMe controllers, PCIe switches, and expanders; optical networking products such as OTN processors and line drivers; security technologies and scalable anti-tamper products; as well as custom design capabilities and services. Founded in 1959 and formerly headquartered in Aliso Viejo, California, Microsemi conducted operations across North America, Europe, Asia including China, Malaysia, Philippines, and India, and other regions, serving customers in automotive, medical, enterprise storage, hyperscale data centers, radar, missile, satellite, and implantable medical device applications. Microsemi's most significant recent development remains its $10.15 billion acquisition by Microchip Technology in May 2018, which expanded Microchip's presence in aerospace, defense, communications, and data center markets, added complementary analog mixed-signal products, and is projected to yield $300 million in annual synergies; post-acquisition, Microchip has integrated Microsemi's offerings, relocated facilities such as a new office in Bengaluru, India in 2025, and advanced related technologies like Switchtec PCIe switches, RISC-V processors, and atomic clock expansions amid ongoing inventory optimization and market recovery efforts.
