This problem affects DDR2 and DDR3 products.
The hard memory controller on Arria V GX, Arria V GT, Arria V SoC, Cyclone V GX, Cyclone V GT, and Cyclone V SoC devices might exhibit read/write errors during normal operation under low Vcc core voltage and extremely hot or cold temperatures.
The following protocols and frequencies are affected:
- For Arria V GX/GT/SoC devices, DDR2 at 375-400 MHz and DDR3 at 375-533 MHz
- For Cyclone V devices, DDR2 at 300-400 MHz and DDR3 at 300-400 MHz.
