Can I interface Quad SPI to MKE14F512VLL16 controller as it support LPSPI and How we can interface it please explain in details.
Hi @prathamesh_h_patil ,
Yes, LPSPI can support QUAD SPI flash. You can refer to this link
https://community.nxp.com/t5/i-MX-RT/LPSPI-how-to-set-for-QSPI-flash-device/m-p/1177734
Unfortunately, we don't have any example of the LPSPI interfacing an external flash.

Hi @prathamesh_h_patil ,
Please see table 56 in datasheet. Frequency of operation can be max to fperiph/2.The max fperiph is from SPLLDIV2. So, max frequency is 168/2/2=42Mhz.
LPSPI doesn't support DDR.

Thanks for information,
Q1. Could you please share Application note for Quad SPI for Flash memory?
Q2. Does MKE14F512VLL16 controller has restriction on particular make Quad Flash memory should use or it is free for any make quad flash?
Q3. Can MKE14F512VLL16 support SPI based Graphical LCD? if yes please share example.
