1.2.5. External Memory Interface Pins

Note: Altera recommends that you create a Quartus® Prime design, enter your device I/O assignments, and compile the design. The Quartus® Prime software checks your pin connections according to I/O assignment and placement rules. The rules differ from one device to another based on device density, package, I/O assignments, voltage assignments, and other factors that are not fully described in this document or the device user guides.
Table 6.  External Memory Interface Pins
Pin Name Pin Functions Pin Description Connection Guidelines
DQS[0:63] I/O, bidirectional

Optional data strobe signal for use in external memory interfacing. These pins drive to the dedicated DQS phase shift circuitry.

Supported I/O standards:

  • POD 1.2-V I/O standard
  • SSTL 1.2-V I/O standard
  • POD 1.1-V I/O standard
  • LVSTL 1.1-V I/O standard
  • LVSTL 1.05-V I/O standard
  • LVSTL700
 Connect unused pins as defined in the Quartus® Prime software.
DQSn[0:63] I/O, bidirectional

Optional complementary data strobe signal for use in external memory interfacing. These pins drive to the dedicated DQS phase shift circuitry.

Supported I/O standards:

  • POD 1.2-V I/O standard
  • SSTL 1.2-V I/O standard
  • POD 1.1-V I/O standard
  • LVSTL 1.1-V I/O standard
  • LVSTL 1.05-V I/O standard
  • LVSTL700
 Connect unused pins as defined in the Quartus® Prime software.
DQ[0:63] I/O, bidirectional

Optional data signal for use in external memory interfacing. Analyze the available DQ pins across all pertinent DQS columns in the device pin-out file.

Supported I/O standards:

  • POD 1.2-V I/O standard
  • SSTL 1.2-V I/O standard
  • POD 1.1-V I/O standard
  • LVSTL 1.1-V I/O standard
  • LVSTL 1.05-V I/O standard
  • LVSTL700

For the DQ pin swapping guidelines, refer to the External Memory Interfaces (EMIF) IP Design Example User Guide: Agilex™ 5 FPGA and SoCs .

Connect unused pins as defined in the Quartus® Prime software.
