Dual Quad SPI Flash Memory
[Figure 2-1, callout 3]
The Quad SPI flash memory located at U2 and U3 provides 2 x 1 Gb of nonvolatile storage
that can be used for configuration and data storage.
• Part number: MT25QU01GBBB8ESF-0SIT (Micron)
• Supply voltage: 1.8V
• Datapath width: 8 bits
• Data rate: variable, depending on single, dual, or quad mode and whether the EMCCLK
or the internal CCLK is used (bitstream configurable). See UltraScale Architecture
Configuration User Guide (UG570) [Ref 3] for more information.
The connections between the SPI flash memories and the XCKU5P device are listed in
Table 3-3.
