The Micron dual MT25QU02GCBB8E12-0sit serial NOR flash Quad SPI flash memory can hold the boot image for the RFSoC system. This interface is used to support QSPI32 boot mode as defined in the Zynq UltraScale+ Device Technical Reference Manual (UG1085) [Ref 3].
The dual Quad SPI flash memory located at U17/U18 provides 4 Gb of non-volatile storage that can be used for configuration and data storage.
•Part number: MT25QU02GCBB8E12-0SIT (Micron)
•Supply voltage: 1.8V
•Datapath width: 8 bits
•Data rate: various depending on single, dual, or quad mode
The configuration and Quad SPI flash memory section of the Zynq UltraScale+ Device Technical Reference Manual (UG1085) [Ref 3] provides details on using the memory. For more Quad SPI details, see the Micron MT25QU02GCBB8E12-0SIT data sheet at the Micron website [Ref 15].
