Hi, We use a STM32F469 and we would like to add 2x512Mbits of NOR FLASH and 128Mbits of SDRAM. Is ST micro recommand some Part Number for FLASH and SDRAM components ? I have not seen any application note. Thanks

The STM32469I-EVAL has 128Mbits NOR FLASH (PN: S29GL128S90FHI0) and 128 Mbits SDRAM (PN : IS42S32800G-6BLI).There is 512Mbits FLASH version of the S29GL family but the access time is higher. Is it an issue for the STM32F469 ?Which requirements have I...
