Through the I2C0 bus U1 PS-side MIO[14:15] pins, the PMU has access to the board power
controller PMBus bus (IRPS5401_SDA/SCL) and power monitor PMBus (INA226_PMBUS_SDA/
SCL). See Figure 7 for addional details.
Refer the Zynq UltraScale+ Device Technical Reference Manual (UG1085) for details about the PMU
interface.
The detailed RFSoC connecons for the feature described in this secon are documented in the
ZCU216 board XDC le, referenced in Appendix B: Xilinx Design Constraints.
SDIO (MIO 39-51)
A PS-side interface to an SD card connector is provided for boong and le system storage. This
interface is used for the SD boot mode and supports SD3.0 access post boot.
SD Card Interface
[Figure 2, callout 7]
The ZCU216 board includes a secure digital input/output (SDIO) interface to provide access to
general purpose non-volale SDIO memory cards and peripherals. Informaon for the SD I/O
card specicaon can be found on the SanDisk Corporaon or SD Associaon websites. The
ZCU216 SD card interface supports the SD1_LS conguraon boot mode documented in the
Zynq UltraScale+ Device Technical Reference Manual (UG1085).
The SDIO signals are connected to ZU49DR RFSoC PS bank 501 which has its VCCMIO set to
1.8V. The six SD interface nets MIO[46:49]_SDIO_DAT[0:3], MIO50_SDIO_CMD, and
MIO51_SDIO_CLK each have a series 30Ω resistor at the Bank 501 source. An NXP
IP4856CX25 SD 3.0-compliant voltage level-translator U23 is present between the ZU49DR
RFSoC and the SD card connector (J23). The NXP IP4856CX25 U23 device provides SD3.0
capability with SDR104 performance.
The following gure shows the connecons of the SD card interface on the ZCU216 board.
