Microchip Technology

Microchip Technology (Nasdaq: MCHP) is a Chandler, Arizona semiconductor company that is among the most important suppliers of radiation-hardened electronics to the global space industry, with space heritage spanning NASA interplanetary probes, GPS satellites, classified national security payloads, and commercial GEO telecommunications spacecraft.

The company's space product portfolio spans three complementary radiation-hardened categories: FPGAs (field-programmable gate arrays) including the RTAX and RTG4 families widely used in satellite data processing, attitude control, and payload signal processing; microprocessors and microcontrollers including radiation-hardened ARM Cortex-based processors and 8/16-bit MCUs for command and data handling; and power management ICs including DC-DC converters, point-of-load regulators, and motor drivers for spacecraft power distribution.

Microchip's space products achieve radiation tolerance ratings of 50-300 krad TID (total ionizing dose) and SEL (single-event latchup) immunity, meeting MIL-PRF-38535 Class V requirements for the harshest military and deep-space environments. The company acquired Microsemi in 2018 for $8.35B, adding Microsemi's extensive space heritage in power management and timing — including GPS timing modules used across U.S. military infrastructure. Microchip's RTAX-S and RT ProASIC3 FPGAs are used in virtually every major U.S. defense satellite program including GPS III, AEHF, WGS, and SBIRS.

For commercial operators, Microchip competes with Xilinx/AMD's space-qualified products and offers COTS-plus options for LEO commercial constellations where lower radiation tolerance is acceptable in exchange for cost savings. The company's San Jose design center focuses on next-generation rad-hard logic nodes.
