Digilent's Nexys4-DDR is a drop-in replacement for our cellular RAM-based Nexys boards due to its end of life. It 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 (Xilinx part number XC7A100T-1CSG324C) and collection of USB, Ethernet, and other ports, the Nexys4-DDR can host designs ranging from introductory combinational circuits to powerful embedded processors. The most notable improvement is the replacement of the 16 MiB CellularRAM with a 128 MiB DDR2 SDRAM memory. Several built-in peripherals, including an accelerometer, a temperature sensor, MEMs digital microphone, speaker amplifier and plenty of I/O devices allow the Nexys4-DDR to be used for a wide range of designs without needing any other components.
