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
Refer the Zynq UltraScale+ Device Technical Reference Manual (UG1085) for details about the PMU
interface.
The detailed RFSoC connections for the feature described in this section are documented in the
ZCU216 board XDC file, referenced in

SDIO (MIO 39-51)

A PS-side interface to an SD card connector is provided for booting and file 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-volatile SDIO memory cards and peripherals. Information for the SD I/O
card specification can be found on the
ZCU216 SD card interface supports the SD1_LS configuration 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 figure shows the connections of the SD card interface on the ZCU216 board.
