    • Power Management Reference design for Xilinx FPGA Spartan-7 platform
    • ROHM, together with Avnet, a leading supplier of electronic products and embedded solutions, developed a reference power supply optimized for Xilinx’s FPGA Spartan-7. In recent years, FPGA power supplies are increasingly demanding high accuracy low voltage, complicated startup sequences. At the same time, designers are constantly faced with the need to upgrade their designs to feature smaller form factors, greater energy savings, and lower costs, which are difficult to achieve within a short period. In response, ROHM offers an optimized power supply reference design for FPGA power supplies that allows designers to reduce development load while meeting market demands. The Spartan-7 (which this reference design was developed for) is ideal for industrial and consumer applications that leverage connectivity with sensor fusion and embedded vision. ROHM’s reference power supply design consists of a verified power supply that safely starts and operates Xilinx’s Spartan-7. This reference power supply includes the BD95602MUV power supply IC that delivers superior response characteristics, along with the BD9B305QUZ, BD9F500QUZ, and BD9F800MUZ designed to provide the current capability demanded for each power supply as well as the BD35395EFJ-M DDR3L termination power supply, making it possible to generate supply voltages that meet FPGA voltage accuracy specifications from 12V input while also supporting the necessary startup sequence. Reference design materials including circuit diagrams, BOMs, and board layouts are available for download.

    • Power Management Reference design for Efinix FPGA Ti180 platform
    • Rohm provides the best power supplies for Efinix FPGA Titanium Ti180 J484 product, and Efinix has developed a development kit for Titanium Ti180 that uses these power supplies as reference power. In recent years, FPGA power supplies are required to have high precision low voltage or complex startup sequences. By providing reference power supplies optimized for FPGAs, Rohm helps designers reduce their development workload and achieve the performance required by the market. The newly launched Ti180 development kit is ideal for vision systems, edge computing, hardware acceleration and machine learning. The reference power supplies are composed of BD95602MUV with excellent response, BD9F500QUZ and BD9F800MUX, which have the necessary current capability for each power supply.

      The design document and user's guide for this development kit can be downloaded from the Efinix's websiteexternal-link.

      You can purchase Titanium Ti180 J484 from Digikey's website external-link.
