Over the last decade satellites and spacecrafts have seen an exponential increase in the need for on-board data processing and storage demands. Additionally, major satellite manufacturers have recently announced their latest satellites to be modular, fully digital and capable of in-orbit reconfigurability. To meet these demands, satellite and payload manufacturers are using high-end FPGAs, ASICs and processors. Microsemi’s RTG4 FPGA is a radiation hardened FPGA that has comparable performance to commercial counterparts in demanding computing applications. The RTG4 requires a complex power solution with multiple low voltage supply rails that can deliver high currents and a need for power supply sequencing to eliminate high inrush currents.

In collaboration with Microchip and Ibeos, Microsemi’s RTG4 development board schematic and layout board were modified to replace the existing power solution that uses commercial grade products with Renesas Radiation Hardened power products. The ISLRTG4DEMO1Z reference board has the same functionality as the Microchip RTG4 Development Kit but includes the space grade power solution from Renesas’ Intersil family of power management ICs.

Contact Renesas for support regarding the rad hard power management ICs in this reference design, for questions on other products please contact the respective manufacturer.
