The LSF is bidirectional, so Quad-SPI can work.

(You still have to size the pull-up resistors correctly for the desired speed, and take into account the drive strength of all connected devices.)

Hi Leon,

QSPI is supported, however the max supported speed is dependent on your external RC as Clemens highlighted. You may also see the TXB0104/ TXB0106 for QSPI level shifting.

Jack
