1 Overview
The Nexys4 DDR board is a complete, ready-to-use digital circuit
development platform based on the latest Artix-7™ Field
Programmable Gate Array (FPGA) from Xilinx®. With its large,
high-capacity FPGA (Xilinx part number XC7A100T-1CSG324C),
generous external memories, and collection of USB, Ethernet, and
other ports, the Nexys4 DDR can host designs ranging from
introductory combinational circuits to powerful embedded
processors. Several built-in peripherals, including an
accelerometer, temperature sensor, MEMs digital microphone, a
speaker amplifier, and several I/O devices allow the Nexys4 DDR
to be used for a wide range of designs without needing any other
components.
The Artix-7 FPGA is optimized for high performance logic, and offers more capacity, higher performance, and more
resources than earlier designs. Artix-7 100T features include:

15,850 logic slices, each with four 6-input LUTs and 8 flip-flops

4,860 Kbits of fast block RAM

Six clock management tiles, each with phase-locked loop (PLL)

240 DSP slices

Internal clock speeds exceeding 450 MHz

On-chip analog-to-digital converter (XADC)
The Nexys4 DDR also offers an improved collection of ports and peripherals, including:

16 user switches

16 user LEDs

Two 4-digit 7-segment displays

USB-UART Bridge

Two tri-color LEDs

Micro SD card connector

12-bit VGA output

PWM audio output

PDM microphone

3-axis accelerometer

Temperature sensor

10/100 Ethernet PHY

128MiB DDR2

Serial Flash

Four Pmod ports

Pmod for XADC signals

Digilent USB-JTAG port for FPGA
programming and
communication

USB HID Host for mice, keyboards
and memory sticks
The Nexys4 DDR is compatible with Xilinx’s new high-performance Vivado® Design Suite as well as the ISE® toolset,
which includes ChipScope™ and EDK. Xilinx offers free WebPACK™ versions of these toolsets, so designs can be
implemented at no additional cost. The Nexys4 DDR is not supported by the Digilent Adept Utility.
