Micro‐SD Card Interface
[Figure 2-1, callout 4]
The KCU116 board includes a secure digital input/output (SDIO) interface allowing the U161
XC7Z010 Zynq
®
-7000 SoC system controller access to general purpose nonvolatile
micro-SD memory cards and peripherals. The micro-SD card slot is designed to support
50 MHz high speed micro-SD cards. The SDIO signals are connected to U161 XC7Z010
Zynq-7000 SoC system controller bank 500, which has its V
CCO
set to SYS_1V8 1.8V. A
MAX13035E level shifter is used between the XC7Z010 system controller (U161), and the
micro-SD card connector (J177). Figure 3-4 shows the connections of the SD card interface
on the KCU116 board.
