Frontgrade offers the highest density and highest performing NAND device in the space industry. 

The UT81NDQ512G8T, 4Tb NAND flash based on the Triple-Level Cell (TLC) NAND technology delivers 32 times the density of the closest competing device available in a single industry standard JEDEC 132 BGA package. 

The UT81NDQ512G8T is Open NAND Flash Interface (ONFI) 4.0 compliant and supports up to 667MT/s throughput (read/write) per pin.  With access to unparalleled storage capacity, designers can significantly increase sensor and digital signal processing throughput in space instruments such as solid-state drives and recorders, reconfigurable computing systems and imaging and communications data buffering applications.


The UT81NDQ512G8T-KU060-EVB evaluation development board provides for a rapid prototyping platform interfacing to the Alpha Data KU060 kit utilizing the Xilinx KU060 Ultrascale FPGA.  The EVB provides access to a single NAND through a VITA 57.1 compatible FMC and has options to startup the I/O at 1.8V or 1.2V.
