COLORADO SPRINGS, Colo. – Cobham Advanced Electronic Solutions in Colorado Springs, Colo., is introducing the UT81NDQ512G8T high-density NAND flash memory device for demanding space applications.

The 4-terabit triple-level cell NAND flash memory module delivers 32 times the density of the closest competing device while fitting into the same industry-standard 12-by-18-millimeter plastic-encapsulated microcircuit package.

With access to this kind of data storage capacity, designers can increase sensor and digital signal processing in applications such as solid-state drives and recorders, reconfigurable computing systems, imaging, and communications data buffering applications.

The module performs as many as 667 mega-transfers per second and complies with Open NAND Flash Interface 4.0 and JEDEC NAND Flash Interoperability (JESD230C) specifications.

While aerospace designers must screen commercial-grade NAND flash to estimate radiation tolerance and operational lifetime, the Cobham radiation-assured flash modules undergo extensive pre-testing for total ionizing dose and single-event effects characterization on a wafer lot-by-lot basis.

Cobham also applies parts, materials and process failure-mode analysis to monitor for potential variations in the semiconductor fabrication process.

The UT81NDQ512G8T 4-terabit NAND flash module supports NV-DDR3 I/O at 667 mega-transfers per second, NV-DDR2 I/O at 533 mega-transfers per second, asynchronous I/O at 50 mega-transfers per second, and TLC endurance of 3,000 program and erase cycles.

The module operates across 2.7-to-3.6-volt input and 1.14-to-1.26-volt, or 1.7-to-1.95-volt output voltage ranges and specified to a temperature range of -40 to 85 Celsius. The 132-ball grid array module is available now in engineering units, with flight models to be released in the second quarter of 2021.
