4.10.1. HyperRAM

HyperRAM is a portfolio of high-speed, low-pin-count memory product that uses the HyperBus interface technology. The Intel® Cyclone® 10 LP FPGA Evaluation Board supports HyperRAM with HyperBus Controller (HBMC) IP provided by Synaptic Labs.

One of the following HyperRAM parts is used:

  • ISSI IS66WVH16M8ALL-166B1LI
  • Cypress S70KS1281DPBHI020

HyperRAM is organized by 16M words x 8 bits with 1.8 V interface.
