Part 13: SD Card Slot
The AX7350B FPGA Development Board contains a Micro
SD card interface to provide user access to the SD card memory,
the BOOT program for the ZYNQ chip, the Linux operating
system kernel, the file system and other user data files.
The SDIO signal is connected to the IO signal of the PS
BANK501 of ZYNQ. Since the VCCMIO of the BANK is set to 1.8V,
but the data level of the SD card is 3.3V, connected through the
TXS02612 level shifter. The schematic of the Zynq7000 PS and SD
card connector is shown in Figure 13-1:
