PMC MIO[44:45] I2C1 Bus
[Figure 3, callout 11]
Bus I2C1 connects the XCVC1902 U1 PS bank 501, and the XCZU4EG system controller U125
PS bank 501 to two I2C switches (TCA9548A U35 and U214). These I2C1 connecons enable
I2C communicaons with other I2C capable target devices. TCA9548A U35 is pin-strapped to
respond to I2C address 0x74. TCA9548A U214 is pin-strapped to respond to I2C address 0x75.
The following gure shows the I2C1 bus connecvity detailed in the rst two tables below. The
I2C0 target device I2C addresses are listed in the third table.
For more informaon on the TCA9548A and TCA6416A, see the Texas Instruments website.
The detailed ACAP connecons for the feature described in this secon are documented in the
VCK190 board XDC le, referenced in Appendix B: Xilinx Design Constraints.
