is described in Table 1-1 with a link to detailed information provided under Feature
Descriptions. Note that the image in Figure 1-2 is for reference only and might not reflect
the current revision of the board.
Electrostatic Discharge Caution
CAUTION! ESD can damage electronic components when they are improperly handled, and can result
in total or intermittent failures. Always follow ESD-prevention procedures when removing and
replacing components.
To prevent ESD damage:
• Use an ESD wrist or ankle strap and ensure that it makes skin contact. Connect the
equipment end of the strap to an unpainted metal surface on the chassis.
• Avoid touching the adapter against your clothing. The wrist strap protects components
from ESD on the body only.
• Handle the adapter by its bracket or edges only. Avoid touching the printed circuit
board or the connectors.
• Put the adapter down only on an antistatic surface such as the bag supplied in your kit.
• If you are returning the adapter to Xilinx Product Support, place it back in its antistatic
bag immediately.

Device Configuration
Zynq-7000 XC7Z020 SoC uses a multi-stage boot process that supports both a non-secure
and a secure boot. The PS is the master of the boot and configuration process. For a secure
boot, the PL must be powered on to enable the use of the security block located within the
PL, which provides 256-bit AES and SHA decryption/authentication.
The ZC702 board supports these configuration options:
• PS Configuration: Quad SPI flash memory
• PS Configuration: Processor System Boot from SD Card (J64)
• PL Configuration: USB JTAG configuration port (Digilent module)
• PL Configuration: Platform cable header J2 and flying lead header J58 JTAG
configuration ports
TIP: Designs using serial configuration based on Quad-SPI flash memory can take advantage of
low-cost commodity SPI flash memory.
The JTAG configuration option is selected by setting SW16 as shown in Table 1-2 and SW10
as described in Programmable Logic JTAG Programming Options for PL configuration
details. SW10 is callout 23 in Figure 1-2.
Note: For more information about Zynq-7000 SoC configuration settings, see the Zynq-7000 SoC
Technical Reference Manual (UG585) [Ref 2].

USB 2.0 ULPI Transceiver
[Figure 1-2, callout 4]
The ZC702 board uses a Standard Microsystems Corporation USB3320 USB 2.0 ULPI
Transceiver at U9 to support a USB connection to the host computer. A USB cable is
supplied in the ZC702 Evaluation Kit (Standard-A connector to host computer, Mini-B
connector to ZC702 board connector J1). The USB3320 is a high-speed USB 2.0 PHY
supporting the UTMI+ low pin interface (ULPI) interface standard. The ULPI standard
defines the interface between the USB controller IP and the PHY device which drives the
physical USB bus. Use of the ULPI standard reduces the interface pin count between the USB
controller IP and the PHY device.

DIP switch SW10[1:2] setting 10 selects the 14-pin header J2 for configuration using either
a Parallel Cable IV (PC4) or Platform Cable USB II. DIP switch SW10 setting 01 selects the
USB-to-JTAG Digilent bridge U23 for configuration over a Standard-A to Micro-B USB cable.
DIP switch SW10 setting 11 selects the JTAG 20-pin header at J58. The four JTAG signals TDI,
TDO, TCK, and TMS would be connected to J58 through flying leads from a JTAG cable. The
3-to-1 analog switch settings are shown in Table 1-10.
FMC Connector JTAG Bypass
When an FPGA mezzanine card (FMC) is attached to J3 or J4 it is automatically added to the
JTAG chain through electronically controlled single-pole single-throw (SPST) switches U25
and U26. The SPST switches are normally closed and transition to an open state when an
FMC is attached. Switch U25 adds an attached FMC to the JTAG chain as determined by the
FMC1_HPC_PRSNT_M2C_B signal. Switch U26 adds an attached FMC to the JTAG chain as
determined by the FMC2_LPC_PRSNT_M2C_B signal The attached FMC card must
implement a TDI-to-TDO connection using a device or bypass jumper to ensure that the
JTAG chain connects to the XC7Z020 SoC.
Clock Generation
The ZC702 board provides three clock sources for the XC7Z020 SoC. Table 1-11 lists the
source devices for each clock.

is connected to XC7Z020 SoC U1 pins Y9 and Y8 respectively. On power-up the user clock
defaults to an output frequency of 156.250 MHz. User applications can change the output
frequency within the range of 10 MHz to 810 MHz through an I2C interface. Power cycling
the ZC702 board reverts the user clock to the default frequency of 156.250 MHz.
• Programmable Oscillator: Silicon Labs Si570BAB0000544DG (10 MHz–810 MHz)
• LVDS Differential Output
The user clock circuit is shown in Figure 1-12.

USB-to-UART Bridge
[Figure 1-2, callout 12]
The ZC702 board contains a Silicon Labs CP2103GM USB-to-UART bridge device (U36)
which allows a connection to a host computer with a USB port. The USB cable is supplied in
the ZC702 Evaluation Kit (Standard-A end to host computer, Type Mini-B end to ZC702
board connector J17). The CP2103GM is powered by the USB 5V provided by the host PC
when the USB cable is plugged into the USB port on the ZC702 board.
The CP2013GM TX and RX pins are wired to the UART_1 IP block within the XC7Z020 SoC PS
I/O Peripherals set. The XC7Z020 SoC supports the USB-to-UART bridge using two signal
pins: Transmit (TX) and Receive (RX).
Silicon Labs provides royalty-free Virtual COM Port (VCP) drivers for the host computer.
These drivers permit the CP2103GM USB-to-UART bridge to appear as a COM port to
communications application software (for example, TeraTerm or HyperTerm) that runs on
the host computer.
IMPORTANT: The VCP device drivers must be installed on the host PC prior to establishing
communications with the ZC702 board.
The USB Connector pin assignments and signal definitions between J17 and U36 are listed
in Table 1-15.

J63 has a second dual-purpose function. The even numbered pins are wired in parallel to
the Arm PJTAG header J41 pins TDI, TIMS, TCK, and TDO. The J41 PJTAG signals are
connected to SoC Bank 13 GPIO pins which simultaneously drive J41 and J63. When J41 is
used for Arm PJTAG functionality, the J63 even numbered pin should not be used. When J63
even numbered pins are used as GPIO, connector J41 should not be used.

Feature Descriptions
PMOD connectors J62 and J63 are wired to the U1 XC7Z020 SoC via TXS0108E 3.3V-to-VADJ
(typically 1.8V) level-shifters.
Figure 1-25 shows the user GPIO male pin header circuits.
When using the PMOD headers on the Zynq-7000 SoC ZC702 evaluation kit, the voltage
level output might appear normal at steady state; however, the rise and fall times on the
other side of the TXS0108E level shifters can be several microseconds. The paralleled LED
driver NDS331N FET has a gate capacitance of ~200 pF. The 200 pF load affects maximum
toggle rate, which is ~100 kHz. There are no speed requirements for PMOD or GPIOs. The
recommendation for a specific high-speed access with GPIO is to use the FMC interface.
Table 1-27 lists the GPIO Header connections to XC7Z020 SoC U1.
Refer to the Zynq-7000 SoC Technical Reference Manual (UG585) [Ref 2] for information
about the PS PJTAG functionality.

Switches
[Figure 1-2, callout 22–26]
The ZC702 board includes a power and a configuration switch:
• Power On/Off slide switch SW11 (callout 26)
• SW4 (FPGA_PROG_B), active-Low pushbutton (callout 22)
Power On/Off Slide Switch
[Figure 1-2, callout 20]
The ZC702 board power switch is SW11. Sliding the switch actuator from the Off to On
position applies 12V power from J60, a 6-pin mini-fit connector. Green LED DS14
illuminates when the ZC702 board power is on. See Power Management for details on the
onboard power system.
CAUTION! Do NOT plug a PC ATX power supply 6-pin connector into J60 on the ZC702 board. The ATX
6-pin connector has a different pinout than J60. Connecting an ATX 6-pin connector into J60 damages
the ZC702 board and voids the board warranty.
Figure 1-26 shows the power connector J60, power switch SW11 and indicator LED DS14.

PS Power-On and System Reset Pushbuttons
[Figure 1-2, callout 27]
Figure 1-28 shows the reset circuitry for the processing system.
Depressing and then releasing pushbutton SW1 causes PS_POR_B_SW to strobe Low.
PS_POR_B: This reset is used to hold the PS in reset until all PS power supplies are at the
required voltage levels. It must be held Low through PS power-up. PS_POR_B should be
generated by the power supply power-good signal.
Depressing and then releasing pushbutton SW2 causes PS_SRST_B_SW to strobe Low.
PS_SRST_B: This reset is used to force a system reset. It can be tied or pulled High, and can be
High during the PS supply power ramps.
Refer to the Zynq-7000 SoC Technical Reference Manual (UG585) [Ref 2] for information
concerning the resets.

VADJ Voltage Control
The VADJ rail is set to 2.5V. When the ZC702 board is powered on, the state of the
FMC_VADJ_ON_B signal wired to header J12 is sampled by the TI UCD9248 controller U33.
If a jumper is installed on J12 signal FMC_VADJ_ON_B is held Low, and the TI controller U33
energizes the VADJ rail at power on.
Because the rail turn on decision is made at power on time based on the presence of the J12
jumper, removing the jumper at J12 after the board is powered up does not affect the 2.5V
power delivered to the VADJ rail and it remains on.
A jumper installed at J12 is the default setting.
If a jumper is not installed on J12, signal FMC_VADJ_ON_B is High, and the ZC702 board
does not energize the VADJ 2.5V at power on. In this mode you can control when to turn on
VADJ and to what voltage level (1.8V, 2.5V or 3.3V only). With VADJ off, the XC7Z020 SoC
still configures and has access to the TI controller PMBUS along with the FMC_VADJ_ON_B
signal. The combination of these allows the user to develop code to command the VADJ rail
to be set to something other than the default setting of 2.5V. After the new VADJ voltage
level has been programmed into TI controller U33, the FMC_VADJ_ON_B signal can be
driven Low by the user logic and the VADJ rail comes up at the new VADJ voltage level.
Installing a jumper at J12 after a ZC702 board powers up in this mode turns on the VADJ rail.
The FMC_VADJ_ON_B signal is sourced by the TCA6416APWR I2C port expander U80 pin 13
(see Figure 1-18).
The I2C port expander IIC_PORT_EXPANDER SDA/SCL bus is wired to the PCA9548ARGER
I2C bus switch (see I2C Bus).
Documentation describing PMBUS programming for the UCD9248 digital power controller
is available at TI [Ref 25].
Monitoring Voltage and Current
Voltage and current monitoring and control are available for selected power rails through
Texas Instruments' Fusion Digital Power graphical user interface. The three onboard TI
power controllers (U32 at address 52 decimal, U33 at address 53 decimal, and U34 at
address 54 decimal) are wired to the same PMBus. The PMBus connector, J59, is provided
for use with the TI USB Interface Adapter PMBus pod (TI part number EVM USB-TO-GPIO,
which can be ordered from the Texas Instruments website [Ref 26] and associated TI Fusion
Digital Power Designer GUI [Ref 27]. This is the simplest and most convenient way to
monitor the voltage and current values for the power rail listed in Table 1-31, Table 1-32,
and Table 1-33.
In each of these the three tables (one per controller), the Power Good (PG) On Threshold is
the setpoint at or above which the particular rail is deemed “good”. The PG Off Threshold is
the setpoint at or below which the particular rail is no longer deemed “good”. The controller

active rail PG states are “good”. The On and Off Delay and rise and fall times are relative to
when the board power on-off slide switch SW12 is turned on and off.

UG850 (v1.7) March 27, 2019
Feature Descriptions
Jumper J37 can be used to select either an external voltage reference (VREF) or on-chip
voltage reference for the analog-to-digital converter.
For external measurements an XADC header (J19) is provided. This header can be used to
provide analog inputs to the XC7Z020 SoC dedicated VP/VN channel, and to the
VAUXP[0]/VAUXN[0], VAUXP[8]/VAUXN[8] auxiliary analog input channels. Simultaneous
sampling of Channel 0 and Channel 8 is supported.
A user-provided analog signal multiplexer card can be used to sample additional external
analog inputs using the 4 GPIO pins available on the XADC header as multiplexer address
lines. Figure 1-32 shows the XADC header connections.
Table 1-34 describes the XADC header J40 pin functions.

Xilinx Design Constraints
Overview
The ZC702 Xilinx® Design Constraints (XDC) template provides for designs targeting the
ZC702 board. Net names in the constraints correlate with net names on the latest ZC702
board schematic. You must identify the appropriate pins and replace the net names below
with net names in your RTL.
See the Vivado Design Suite User Guide: Using Constraints (UG903) [Ref 12] for more
information.
The FMC LPC connectors J3 and J4 are connected to 2.5V VADJ banks. Because different
FMC cards implement different circuitry, the FMC bank I/O standards must be uniquely
defined by each customer.
Note: The ZC702 ucf/xdc files are under the Documentation tab of the Zynq-7000 SoC ZC702
Evaluation Kit product page. Click the Board Files check box, find the XTP185 ZC702 Schematics
entry, and expand the Associated File(s) list.

Safety
IEC 60950-1:2005, Information technology equipment – Safety, Part 1: General requirements
EN 60950-1:2006, Information technology equipment – Safety, Part 1: General requirements
Markings
In August of 2005, the European Union (EU) implemented the EU
WEEE Directive 2002/96/EC and later the WEEE Recast Directive
2012/19/EU requiring Producers of electronic and electrical
equipment (EEE) to manage and finance the collection, reuse,
recycling and to appropriately treat WEEE that the Producer places
on the EU market after August 13, 2005. The goal of this directive is
to minimize the volume of electrical and electronic waste disposal
and to encourage re-use and recycling at the end of life.
Xilinx has met its national obligations to the EU WEEE Directive by
registering in those countries to which Xilinx is an importer. Xilinx
has also elected to join WEEE Compliance Schemes in some
countries to help manage customer returns at end-of-life.
If you have purchased Xilinx-branded electrical or electronic
products in the EU and are intending to discard these products at
the end of their useful life, please do not dispose of them with your
other household or municipal waste. Xilinx has labeled its branded
electronic products with the WEEE Symbol to alert our customers
that products bearing this label should not be disposed of in a
landfill or with municipal or household waste in the EU.
This product complies with Directive 2002/95/EC on the restriction
of hazardous substances (RoHS) in electrical and electronic
equipment.
This product complies with CE Directives 2006/95/EC, Low Voltage
Directive (LVD) and 2004/108/EC, Electromagnetic Compatibility
(EMC) Directive.
