Chapter 2: Signals, Interfaces, and Pins
Quad-SPI Interface: The lower memory Quad-SPI interface (QSPI_0) must be used if the Quad-SPI
memory subsystem is to be used. The upper interface (QSPI_1) is optional and is only used for a
two-memory arrangement (parallel or stacked). Do not use the Quad-SPI 1 interface alone.
MIO Pins [8:7] are Outputs: These MIO pins are available as output only. GPIO channels 7 and 8 can
only be configured as outputs.
MIO Pins in 7z007s and 7z010 CLG225 Devices: 7z010 dual core and 7z007s single core CLG225
devices have 32 MIO pins, 0:15, 28:39, 48, 49, 52, and 53. All other Zynq-7000 AP SoC devices include
all 54 MIO pins and all devices have the same EMIO interface functionality. Refer to section
1.1.3 Notices.
The 32 MIO pins available in the 7z007s and 7z010 devices restrict the functionality of the PS:
Either one USB or one Ethernet controller via MIO
No boot from SD Card
No NOR/SRAM interfacing
Width of NAND Flash limited to 8 bits
