Dual Quad Spi Flash Memory - Xilinx KCU116 User Manual

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)
The connections between the SPI flash memories and the XCKU5P device are listed in
Table 3-3.
