QDR II+ Memory Size in VCU110 EVM

Jump to solution

From the Xilinx VCU110 EVM BoM, we see that the QDRII+ IC used is of size 144Mb. But in the schematics symbol and part it is mentioned is 36Mb. Please confirm which part is used in EVM?

Schematic symbols may not be updated, BOM is final so QDRII+ SRAM is 144Mb

Below is the text from  UG1073 which clearly states 144Mb 

 

"VCU110 Evaluation Board Features

The VCU110 evaluation board features are listed here.

Detailed information for each feature is provided in Feature Descriptions, starting on page 12.

• Virtex UltraScale XCVU190-2FLGC2104EES9847 FPGA

144 Mb QDRII+ component memory interface (1 x 18-bit SIO device)"

 

Hope this clarifies

Hi @raja1,

 

The QDRII+ size is 144Mb . The 144 Mb QDR2+ part no is Cypress CY7C2663KV18-550BZXC located at U168.

 

Thanks,

Sarada
