Can F1152 and F1517 packages in Stratix IV GX devices support x32/x36 DQS/DQ group?

Description

Yes, the Stratix® IV GX EP4SGX290, EP4SGX360, and EP4SGX530 devices in the F1152 and F1517 packages can support x32/x36 DQS/DQ group in Quartus® II software version 9.1SP2 and later.

 

External Memory Interface Handbook volume 2, section I, Device and Pin Planning (PDF) incorrectly states that EP4SGX290, EP4SGX360, and EP4SGX530 devices in the F1152 and F1517 packages can not support x32/x36 DQS/DQ group.

 

For more information, refer to the Stratix IV device handbook, Chapter 7 External Memory Interface in Stratix IV Devices (PDF).

 

This information will be updated in a future release of the External Memory Interface Handbook.
