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.
