An external power supply (e.g. wall wart) can be used by plugging it into the power jack (J18)
and setting jumper JP5 to “REG”. The supply must use a coax, center-positive 2.1mm
internal-diameter plug, and deliver 7VDC to 15VDC. Suitable supplies can be purchased from
the Digilent website or through catalog vendors like DigiKey. Power supply voltages above
15VDC might cause permanent damage. A suitable external power supply is included with
the Arty Z7 accessory kit.
Similar to using an external power supply, a battery can be used to power the Arty Z7 by
attaching it to the shield connector and setting jumper JP5 to “REG”. The positive terminal of
the battery must be connected to the pin labeled “VIN” on J7, and the negative terminal must
be connected to the pin labeled GND on J7.
The on-board Texas Instruments TPS65400 PMU creates the required 3.3V, 1.8V, 1.5V, and
1.0V supplies from the main power input. Table 1.1 provides additional information (typical
currents depend strongly on Zynq configuration and the values provided are typical of
medium size/speed designs).
The Arty Z7 does not have a power switch, so when a power source is connected and selected
with JP5 it will always be powered on. To reset the Zynq without disconnecting and
reconnecting the power supply, the red SRST button can be used. The power indicator LED
(LD13) is on when all the supply rails reach their nominal voltage.

2 Zynq APSoC Architecture
The Zynq APSoC is divided into two distinct subsystems: The Processing System (PS) and
the Programmable Logic (PL). Figure 2.1 shows an overview of the Zynq APSoC
architecture, with the PS colored light green and the PL in yellow. Note that the PCIe Gen2
controller and Multi-gigabit transceivers are not available on the Zynq-7020 or Zynq-7010
devices.
