The new HyperRAM memories, based on low-power PSRAM technology, are very welcome addition to the traditional RAM memories portfolio.They provide good bandwidth performance while using a limited amount of pins.The interface, known as « HyperBus », offers a low signal count (Address, Command and Data using only eight DQ pins), Low Power consumption, Hidden Refresh, Automotive Temperature. These memories are optimized for Mobile and Automotive applications. Typical power consumption during burst read is about 60mA.ALSE has then designed a very-low resource usage HyperBus Memory Controller, in order to provide an easy interface to the HyperRAM memories, along with high performance (up to 333 MBytes/s, which is x1.5 times faster than a 16 bits PSRAM running @ 108MHz).


  • Up to 333MBytes/s, with only 12 pins used and only 60mA power consumption
  • Very low resource usage, enabling IP integration in the smallest FPGA
  • Burst Oriented access, for optimized access and bandiwdth
  • User Access to HyperRAM registers, to configure memory settings (Output drive strength, Burst wrap, etc ...)
  • Sophisticated SDC Timing Constraints, for easy Timing Convergence. Easy integration thanks to QIP file.

Device Utilization and Performance

Intel® Cyclone® 10 LP : around 300 LEs, 2 M9Ks. Up to 166MHz clocking.

Getting Started

Contact ALSE to evaluate our solution on your own board, or on an Intel Dev Kit.ALSE can provide a Hardware Tester reference design, and the customer can also use an Intel FPGA IP Evaluation mode (formerly known as OpenCore Plus) version of the IP.
