Hi,

Please refer the datasheet.

Thanks for your valuable reply, @Zhiming_Liu .

Can you please confirm the maximum clock/data rate of QSPI interface supported by i.MX8M Plus processor

Hi,

SDR (single data rate) SCK = 166 MHz (max). That’s 166M transfers/sec.

DDR mode also lists 166 MHz as the clock but transfers on both edges, so DDR effectively gives 2 transfers/clock (≈332 MT/s)
