Renesas Electronics has developed a complete space-ready reference design for AMD’s Versal adaptive system-on-chip (SoC)

The ISLVERSALDEMO2Z reference design integrates key radiation-hardened components for power management for the XQRVC1902., including four new and recently released products in an ultra-compact design.

The Intersil-brand ICs are specifically designed to support a wide range of power rails for next-generation space avionics systems that demand tight voltage tolerances, high current, and efficient power conversion while withstanding the harsh environment of space.

As core voltages decrease and currents increase for FPGAs and ASICs, it has become more 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.

The ISLVERSALDEMO2Z generates each of the power rails used by the Versal devices, including a low 0.80V core voltage supply that can source up to 140 A (amps) of current.

It has a 4.5V to 19V input voltage range and output voltage as low as VREF: 0.6V+/- 0.67% (temperature, radiation and life) with differential remote sensing of output voltage and a temperature operating range of -55 °C to +125 °C.

“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 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,” said 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.”

The reference design includes the ISL73847SEH Rad-Hard Dual Output PWM Controller and interfaces with ISL73847SEH synchronous buck controller with GaN FET half-bridge drivers, ISL73007SEH Rad-Hard 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 centimeters of board area, approximately equivalent to two business cards and are available in ceramic (ISL73041SEH) or plastic packaging (ISL71441M).

The reference design also comes with all of the design files that customers need for rapid integration into their systems, including schematics, bill-of-materials and PCB Gerber files.

All the devices in the reference design are available today and design is available upon request in limited quantities.
