Zynq UltraScale+ ZCU102 DDR4 VDDSPD Voltage

Jump to solution

Hello,

 

I realized that ZCU102 board uses 3.3V for VDDSPD voltage of DDR4 SODIMM module.

 

DDR4 SODIMM modules expect nominal 2.5V (for example MTA18ASF1G72HZ DDR4 SODIMM module).

 

I guess there is a mistake but I wonder that if anyone is faced with a problem for this reason?

 

Regards,

Ali

@muh_ali The ZCU102 kit comes with Kingston KVR21SE15S8/4 installed which supports VDDSPD of 2.2V to 3.6V . Hence you see 3.3V for VDDSPD.
