Zybo Z7 Board Reference Manual
Overview
The Zybo Z7 is a feature-rich, ready-to-use embedded software and digital circuit development board built around
the Xilinx Zynq-7000 family. The Zynq family is based on the Xilinx All Programmable System-on-Chip (AP SoC)
architecture, which tightly integrates a dual-core ARM Cortex-A9 processor with Xilinx 7-series Field Programmable
Gate Array (FPGA) logic. The Zybo Z7 surrounds the Zynq with a rich set of multimedia and connectivity peripherals
to create a formidable single-board computer, even before considering the flexibility and power added by the
FPGA. The Zybo Z7's video-capable feature set, including a MIPI CSI-2 compatible Pcam connector, HDMI input,
HDMI output, and high DDR3L bandwidth, was chosen to make it an affordable solution for the high end
embedded vision applications that Xilinx FPGAs are popular for. Attaching additional hardware is made easy by the
Zybo Z7's Pmod connectors, allowing access to Digilent's catalog of over 70 Pmod peripheral boards, including
motor controllers, sensors, displays, and more.
The Zybo Z7 is a direct replacement for the popular
Zybo development board,
which will soon be phased out of
production. The designs are very similar, however the Zybo Z7 adds several features and performance
improvements. To assist in migrating from the Zybo to the Zybo Z7, Digilent has created a migration guide,
available on the
Zybo Z7 Resource Center.

Zybo Z7 Board Reference Manual
Purchasing Options
The Zybo Z7 can be purchased with either a Zynq-7010 or Zynq-7020 loaded. These two Zybo Z7 product variants
are referred to as the Zybo Z7-10 and Zybo Z7-20, respectively. When Digilent documentation describes
functionality that is common
to both of these variants, they are referred to collectively as the “Zybo Z7”. When
describing something that is only common to a specific variant, the variant will be explicitly called out by its name.
The primary difference between the two variants is the size of the FPGA inside the Zynq AP SoC. The Zynq
processors both have the same capabilities, but the -20 has about a 3 times larger internal FPGA than the -10. Also,
The Zynq-7010 has slightly fewer FPGA attached pins than the Zynq-7020, which means several features found on
the Zybo Z7-20 are not available on the Zybo Z7-10. The differences between the two variants are summarized
below:
Product Variant
Zynq Part
1 MSPS On-chip ADC
Look-up Tables (LUTs)
Flip-Flops
Block RAM
Clock Management Tiles
Total Pmod ports
Fan connector

The Zybo Z7-20 includes a fan and heat sink in order to dissipate the extra heat generated from the additional
FPGA resources when running complex, fast-switching designs.
The board can be purchased stand-alone or with a voucher to unlock the Xilinx SDSoC toolset. The SDSoC voucher
unlocks a 1 year license that can be used with the Zybo Z7. After the license expires, any version of SDSoC that was
released during this 1 year period can continue to be used indefinitely. For more information on purchasing, see
the
Zybo Z7 Product Page.
At the time of purchase, it is also possible to add-on a microSD card, 5V 2.5A power
supply, and micro USB cable as needed.
