关于Arria 10 QDR IV的疑问

[AMa]

请教下~

Arria 10如果接QDR IV，最大位宽可以是多少？也就是最大可以接多少pcs(QDR颗粒36bit)，接法是跟DDR3/4一样嘛?

另外~datasheet内说，可以支持到1066Mhz，这个是指的-1的器件 还是所有器件都可以支持到？

Dear AMa,

Thank you for joining this Intel Community.

You may refer to EMIF spec estimator tools in link provided below . This tool allows you to find and compare the performance of the supported external memory interfaces in Intel® FPGAs. You’ll be able to filter down to specific features based on your targeted specifications . It also will show you what is the data width and speed grade supported based on the criteria you have chosen for analysis.

I sincerely hope this helps. 😊 Let me know if you have any question.

Thanks

Hi AMa,

Additional information here for DDR3/DDR4 supported in Arria 10 Device Packages. You may refer to this Arria 10 handbook under section "6.5. Memory Interfaces Support in Intel Arria 10 Device Packages" (page 194). You will be able to see maximum interfaces that can be supported per device package starting from Table 75 to Table 88.
