• FPGA based ready-to-use digital circuit development platform
• 15,850 logic slices and 240 DSP slices
• 4,860 Kbits of fast block RAM
• On-chip analog-to-digital converter (XADC)

The Nexys4 Artix-7 FPGA Board is a ready-to-use digital circuit development platform designed to bring additional industry applications into the classroom environment. With its large, high-capacity FPGA  and collection of USB, Ethernet, and other ports, the Nexys 4 DDR can host designs ranging from introductory combinational circuits to powerful embedded processors. Several built-in peripherals, including an accelerometer, a temperature sensor, MEMs digital microphone, speaker amplifier and plenty of I/O devices allow the Nexys 4 DDR to be used for a wide range of designs without needing any other components. The most notable improvement is the replacement of the 16 MiB CellularRAM with a 128 MiB DDR2 SDRAM memory. Digilent will provide a VHDL reference module that wraps the complexity of a DDR2 controller and is backwards compatible with the asynchronous SRAM interface of the CellularRAM, with certain limitations. 

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)
