The evolution of power distribution in the spacecraft goes into a modular architecture direction. Especially the secondary power distribution from the satellite bus to the modules can be made more efficient by applying modular design and standard power interfaces.
Microchip takes a proven automotive-qualified device and improves the silicon process to make the component immune to single-event latch-up in heavy ions, thus preventing destruction in the radiation environment of space.
Microchip’s AVR8 ATmegaS64M1/ATmegaS128 and ARM32 M7 SAMV71Q21 Flight Models (FM) are available in ceramic package with screening equivalent to QML class Q and QML class V quality levels. Engineering samples are available as well.
Developing radiation-hardened systems for space applications means long lead times and high cost toward achieving the necessary levels of reliability for multi-year missions in harsh environments.
Two microcontrollers for space, the ATSAMV71Q21RT from Microchip Technology Nantes (formerly Atmel) and the UT32M0R500 from Cobham Microelectronic Solutions (formerly Aeroflex), are compared in this post
Microchip’s technical experts and partners will be presenting the most innovative space-related products, capabilities, and system solutions in this one-day technology forum. The attendees will see demonstrations of how the interoperation of our latest products can accelerate their development time. They´ll also gain a comprehensive understanding of how Microchip’s Sub-QML and COTS-to-RT components help address the challenges of meeting system performance and reliability goals while also saving costs.
In modern satellites, the secondary power conditioning unit must supply a wide variety of low voltages, which are required by the payload modules, precisely and without fluctuations even at severe load variations.
