Renesas Electronics Corporation, a provider of advanced semiconductor solutions, announced a complete, space-ready reference design for the AMD Versal XQRVC1902 adaptive system-on-chip (SoC).
Developed in collaboration with AMD, the ISLVERSALDEMO2Z reference design integrates key radiation-resistant components for power management, including four new and recently released products in an ultra-compact design.
These Intersil-branded ICs are specifically designed to support a wide range of power rails for next-generation space avionics systems that require tight voltage tolerances, high current, and efficient power conversion while also withstanding the harsh environment of space. .
As core voltages decrease and currents increase for FPGAs and ASICs, it becomes more difficult to meet the stringent power requirements of these devices to ensure they operate error-free. This is especially critical in space missions where energy availability is limited and systems are exposed to extreme temperatures and radiation for a long period of time.
Renesas collaborated with AMD to develop a complete power management solution for the AMD Versal platform to address these challenges. The Versal Adaptive SoC is a space-grade computing platform that offers full radiation tolerance, accelerated AI inference, and high-bandwidth signal processing performance. The ISLVERSALDEMO2Z generates each of the power rails used by the Versal platform, including a 0.80V low center voltage source that can deliver up to 140A (amps) of current.
“As the number of satellite and spacecraft launches continues to accelerate rapidly, high-performance computing platforms like the Versal Adaptive SoC are becoming more prevalent, necessitating new power solutions,” said Chris Stephens, Vice -president and general manager of Renésias' HiRel business division. “Our new reference design was meticulously engineered to meet the rigorous demands of space operations while integrating all essential components into a very small space. It is an ideal turnkey solution for Versal Adaptive SoC power management.”
“Power management for high-performance digital platforms like our AMD XQRVC1902 Versal space-grade adaptive SoCs cannot be taken for granted, especially when used in the harsh environment of space,” said Minal Sawant, senior director of Vertical Market Aerospace and Defense. , OMG. “The combination of our radiation-tolerant Versal space-grade SoC and the Renesas ISLVERSALDEMO2Z power solution provides our customers with the precision, efficiency and reliability that are critical to successfully executing space missions.”
Renesas' new reference design comes with a series of power management devices that have been tested and verified to withstand exposure to high levels of radiation. These include pulse width modulation (PWM) controllers, GaN FET half-bridge drivers, point-of-load (POL) regulators, power and enable switches, and power sequencers. The devices come in compact packaging, so the main power rail components occupy just 104 square centimeters of board area, approximately the equivalent of two business cards.
Additionally, ISLVERSALDEMO2Z comes with all the design files customers need for quick integration into their systems, including schematics, bills of materials, and PCB Gerber files.
