Quad SPI Flash Memory (MIO 0–5)
[Figure 2-1, callout 4]
The Micron MT25QU512ABB8ESF serial NOR flash Quad SPI flash memory can hold the boot
image for the MPSoC system. This interface is used to support QSPI32 boot mode as
defined in the Zynq UltraScale+ MPSoC Technical Reference Manual (UG1085) [Ref 2].
The Quad SPI flash memory (U119) is located on the bottom of the board, and provides
512 Mb of non-volatile storage that can be used for configuration and data storage.
• Part number: MT25QU512ABB8ESF-0SIT (Micron)
• Supply voltage: 1.8V
• Datapath width: 4 bits
• Data rate: Various depending on single, dual, or quad mode
The connections between the SPI flash memory and the XCZU7EV MPSoC are listed in
Table 3-6.
