STM32WL33 QSPI VS SPI

CEagl.1
Associate III

Hi 
I am hoping someone might be able to help me with some calculations.

I am assessing the STM32WL33 for use in a product.
One of the peripherals will be an EEPROM, an M95P32.

The EEPROM supports Dual/Quad Output (Read) However the STM32 does not appear to have a hardware QSPI.

So i am trying to determine whether to implement a Quad Read in software (bitbanging).

Can anyone help me to understand the max data transfer on 4 wire SPI using hardware, Vs that of Quad Read using software.

 

Many thanks
