STM32L4S5VIT - FMC IO signalling level change

Hello,

I want to connect a muxed PSRAM (ref: W956D6KBKX) with STM32L4S5VIT in LQFP100 package, The PSRAM requires IO signals at 1.8V. and in the MCU tension is fixed at 3.3V.

So is it advisable to use level translators to convert the IO signals from 3.3V to 1.8V. and vice versa?

The Level translators will disrupt the timing of signal ?

Can you please suggest me if there is any suitable solution for this.

Thanks,

Zakaria
