Hello! Thank you for your question regarding the QSPI interface on the i.MX8M Mini and i.MX8M Plus.
Based on the provided documentation, the precise maximum data rates and clock frequencies for the QSPI (FlexSPI) interface are not explicitly listed in the Toradex module datasheets.
Here is what is known from the references:
-
Verdin iMX8M Plus: The QSPI interface is supported through the Flexible SPI (FlexSPI) Controller with a single channel available on the module edge connector. While it supports single, dual, and quad modes, octal mode is not available via the edge connector.
Verdin iMX8M Plus Datasheet, Section 5.12 -
Verdin iMX8M Mini: Similarly, the FlexSPI controller supports single, dual, quad, and octal modes (the latter only when both SPI channels are available, which is limited by module variant and availability of Wi-Fi).
Verdin iMX8M Mini Datasheet, Section 5.12
However, the Toradex datasheets do not state the exact maximum clock frequency or data rate for QSPI. For typical NXP i.MX8M Mini/Plus SoCs, FlexSPI modules can commonly support up to 133 MHz clock, equating to theoretical peak data rates of several hundred Mbit/s in quad mode, but this depends on the SoC variant, board design, and connected peripheral.
For your exact module and carrier board combination, please refer directly to:
If you need further details, you may want to check the official NXP reference manuals for the i.MX8M Mini and Plus SoCs, or share more about your specific use case so I can assist further with configuration details.
Best regards,
