Overview
The Nexys4 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
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 a lot of I/O devices allow the Nexys4 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 450MHz

On-chip analog-to-digital converter (XADC)
