I/O logic support at 1.2V for QSPI

saminathan · ‎2026-01-20

Hi,

we are planning to use STM32H742xI/G controller in our design, we have reviewed the datasheet and need a clarification on the IO logic for QSPI.

Does this controller supports 1.2v IO logic for the QSPI.

Hello @saminathan and welcome to the community;

Unfortunately, 1V2 IO logic for QUADSPI interface isn't supported. Please look at this post.
