STM32H7S7L8H6 Quad SPI - VDDXSPI supply voltage

[JK1234]

Hello Team,

We are planning to use STM32H7S7L8H6 in our design. With this part we want to integrate quad SPI Flash memory (Part Number :  W25Q128JVPIM with 3.3V Vcc).

So, in STM32H7S7L8H6 VDDXSPI supply voltage 3.3V is ok, right?

Thanks & Regards,

Hello @JK1234 

As documented in the datasheet under the "General Operating Conditions" table, the VDDXSPIx voltage range varies between 1.62 V and 3.6 V when HSLV = 0, and between 1.08 V and 2.7 V when HSLV = 1.
Therefore, you should be aware not to activate HSLV if your VDDXSPI is 3.3 V.

Best regards,
