Micro-SD Card Interface

[Figure 1-2, callout 8]
The VCU110 board includes a secure digital input/output (SDIO) interface to provide user
access to general purpose nonvolatile micro-SD memory cards for configuration. The
micro-SD card slot is designed to support 50 MHz high speed micro-SD cards. The SDIO
signals are connected to U111 XC7Z010 Zynq SoC system controller Bank 500, which has its
V set to SYS_1V8 1.8V. A MAX13035E level-shifter (U154) is used between the XC7Z010
CCO
System Controller (U111) and the micro-SD card connector (J83).
