SDRAM in IMXRT1170

Hello All,

 We are building an application HW board using iMXRT1170 controller  for a 5 " TFT  interface. We referred to EVK iMXRT1170   and seen that the board uses 2 external SDRAM's ( SDRAM 16bit * 2 =
:W9825G6KH-5I  2 No's )  )  of the same size ( 4x 4Mx 16 = 256Mbits ) )application.  Are these 2 SDRAM s are used simultaneously to store/access data by the controller.

 For a smaller application with TFT interface, can we use just one SDRAM unless micro interface mandates 2 SDRAM's. 

Thank you.

@Sharma 

I use a single 16 bit SDRAM on both 1171 and 1176 designs, works fine.

I have attached my design below. I changed the DCD.c file to match this (also below)
Also some additional info here: https://community.nxp.com/t5/i-MX-RT/Error-in-debug-ini-file-for-SDRAM-for-Keil-in-SDK-for-RT117x/m-...

 

Maybe it can help you
