Feature Descriptions
Figure 1-7
shows the USB 2.0 ULPI Transceiver circuitry. Note that the shield for the USB
Mini-B connector (J1) can be tied to GND by a jumper on header J36 pins 1–2 (default). The
USB shield can optionally be connected through a capacitor to GND by installing a
capacitor (body size 0402) at location C202 and jumping pins 2-3 on header J36.
SD Card Interface
[
Figure 1-2
, callout

]
The ZC702 board includes a secure digital input/output (SDIO) interface to provide
user-logic access to general purpose non-volatile SDIO memory cards and peripherals.
Information for the SD I/O card specification can be found at the SanDisk Corporation
[Ref 3]
or SD Association
[Ref 4]
websites.
The SDIO signals are connected to XC7Z020 AP SoC PS bank 501 which has its VCCMIO set
to 1.8V. A TXB02612 SDIO port expander with voltage-level translation (U61) is used
between the XC7Z020 AP SoC and the SD card connector (J64).
