Quad-SPI Flash Memory (MIO 0–12)
[Figure 2-1, callout 4]
The Micron dual MT25QU512ABB8ESF serial NOR flash Quad-SPI memories are capable of
holding the boot image for the MPSoC system. To achieve higher performance two
Quad-SPI devices are connected in parallel and provide an 8-bit data bus for booting and
configuration. This interface is used to support QSPI32 boot mode as defined in the Zynq
UltraScale+ MPSoC Technical Reference Manual (UG1085) [Ref 2].
The dual Quad-SPI flash memory located at U119/U120 provides 1 Gb of non-volatile
storage that can be used for configuration and data storage.
• Part number: MT25QU512ABB8ESF-0SIT (Micron)
• Supply voltage: 1.8V
• Datapath width: 8 bits
• Data rate: Various depending on Single/Dual/Quad mode
The connections between the SPI flash memory and the XCZU9EG MPSoC are listed in
Table 3-6.
The configuration and Quad-SPI section of the Zynq UltraScale+ MPSoC Technical Reference
Manual (UG1085) [Ref 2] provides details on using the Quad-SPI flash memory. For more
QSPI details, see the Micron MT25QU512ABB8ESF-0SIT data sheet at the Micron website
[Ref 13].
