Reference Design Packs A number of Rad-Exhausting Core Energy Rails in Extremely-Compact Footprint, Delivering Turnkey Effectivity and Precision
Renesas Electronics Company, a premier provider of superior semiconductor options, right now introduced a whole space-ready reference design for the AMD Versal™ adaptive system-on-chip (SoC) XQRVC1902. Developed in collaboration with AMD, the ISLVERSALDEMO2Z reference design integrates key radiation-hardened elements for energy administration, together with 4 new and not too long ago launched merchandise in an ultra-compact design. These Intersil-brand ICs are particularly designed to assist a variety of energy rails for next-generation house avionics techniques that demand tight voltage tolerances, excessive present, and environment friendly energy conversion whereas withstanding the cruel surroundings of house.
As core voltages lower and currents enhance for FPGAs and ASICs, it has develop into harder to fulfill the stringent energy necessities of those units to make sure that they function error-free. That is particularly essential in house missions the place energy availability is proscribed, and techniques are uncovered to excessive temperatures and radiation for an prolonged time period.
To deal with these challenges, Renesas has collaborated with AMD to develop a whole energy administration answer for the AMD Versal platform. The Versal Adaptive SoC is an industry-leading space-grade compute platform that delivers full radiation tolerance, accelerated AI inference, and high-bandwidth sign processing efficiency. The ISLVERSALDEMO2Z generates every of the facility rails utilized by the Versal platform, together with a low 0.80V core voltage provide that may supply as much as 140 A (amps) of present.
“Because the variety of satellite tv for pc and spacecraft launches continues to speed up quickly, high-performance computing platforms such because the Versal Adaptive SoC have gotten extra prevalent, necessitating new energy options,” stated Chris Stephens, Vice President, and Normal Supervisor of the HiRel Enterprise Division at Renesas. “Our new reference design has been meticulously engineered to fulfill the rigorous calls for of operations in house whereas integrating all the important elements into a really small footprint. It is a perfect turnkey answer for Versal Adaptive SoC energy administration.”
“Energy administration for high-performance digital platforms like our AMD XQRVC1902 Versal space-grade adaptive SoCs can’t be taken with no consideration, notably when they’re used within the harsh surroundings of house,” stated Minal Sawant, senior director, Aerospace & Protection Vertical Market, AMD. “The mixture of our radiation-tolerant Versal space-grade SoC and Renesas ISLVERSALDEMO2Z energy answer supplies our prospects with the precision, effectivity, and dependability which are paramount for the profitable execution of house missions.”
Renesas’ new reference design comes with an array of energy administration units which have been examined and verified to resist publicity to excessive ranges of radiation. These embody Pulse Width Modulation (PWM) controllers, GaN FET half-bridge drivers, point-of-load (POL) regulators, energy and allow switches, and energy sequencers. The units are available small-footprint packages, so the core energy rail elements take up simply 104 sq. centimeters of board space, roughly equal to 2 enterprise playing cards.
Moreover, the ISLVERSALDEMO2Z comes with all the design recordsdata that prospects want for speedy integration into their techniques, together with schematics, bill-of-materials and PCB Gerber recordsdata.
