Developed in collaboration with AMD, the ISLVERSALDEMO2Z reference design integrates key radiation-hardened components for power management, including four new and recently released products in an ultra-compact design.
These Intersil-brand ICs have been 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 being able to withstand the harsh environment of space.
As core voltages decrease and currents increase for FPGAs and ASICs, it has become increasingly difficult to meet the stringent power requirements of these devices to ensure that they operate error-free. This is especially critical in space missions where power availability is limited, and systems are exposed to extreme temperatures and radiation for an extended period of time.
To address these challenges, Renesas has collaborated with AMD to develop a complete power management solution for the AMD Versal platform.
The Versal Adaptive SoC is a space-grade compute platform that delivers full radiation tolerance, accelerated AI inference and high-bandwidth signal processing performance. The ISLVERSALDEMO2Z generates each of the power rails utilised by the Versal platform, including a low 0.80V core voltage supply that can source up to 140 A (amps) of current.
“As the number of satellite and spacecraft launches continues to accelerate rapidly, high-performance computing platforms such as the Versal Adaptive SoC are becoming more prevalent, necessitating new power solutions,” said Chris Stephens, Vice President, and General Manager of the HiRel Business Division at Renesas. “Our new reference design has been meticulously engineered to meet the rigorous demands of operations in space, while integrating all of the essential components into a very small footprint. 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, particularly when they are used in the harsh environment of space,” explained Minal Sawant, senior director, Aerospace & Defense Vertical Market, AMD. “The combination of our radiation-tolerant Versal space-grade SoC and Renesas ISLVERSALDEMO2Z power solution provides our customers with the precision, efficiency, and dependability that are paramount for the successful execution of space missions.”
Renesas’ reference design comes with an array 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 small-footprint packages, so the core power rail components take up just 104 square centimetres of board area, approximately equivalent to two business cards.
Additionally, the ISLVERSALDEMO2Z has all of the design files that customers need for rapid integration into their systems, including schematics, bill-of-materials and PCB Gerber files.
