DA14683 access QSPI-RAM (PSRAM)

Hi Dialog,

As we know,  DA1469x can access  QSPI-RAM chip through its Quad SPI RAM/FLASH Controller.

Is possible  for DA14683 to access QSPI-RAM chip (such as APS6404L) through its Quad SPI controller ?

Thanks, Peter

Hi Peter Luo,

Hi Peter Luo,

This is not possible in DA1468x product family, because there isn’t a Quad SPI RAM/FLASH Controller, as in DA1469x.

In case of DA1469x, please check dg_configUSE_HW_QSPI2 macro definition. You should set to 1 in the custo_config_xxxx.h to add PSRAM support. In the 12.2 of the AN-B-074: DA1469x emWin Graphic Library and GUI you will find detailed step for how to connect an external QSPI RAM,

Thanks, PM_Dialog
