    An open source PSRAM/HyperRAM controller for Sipeed Tang Nano 9K / Gowin GW1NR-LV9QN88PC6/15 FPGA

    • Another difference that I find in that W955D8MBYA data sheet compared to W955N8MBY, is that W955D8MBYA does not mention anywhere that differential signaling would be optional: but instead it marks it as required. If that is the case, then the question for Best Behavior(tm) of how to properly feed it LVDS does rise again. ( https://github.com/zf3/psram-tang-nano-9k/issues/1 )
