Datasheet

The Rad Hard high density NAND flash memory, from Data Device Corporation (DDC), has been selected to be integrated within the Pearl Single Board Computer (SBC), that is used as the flight computer on NASA’s BioSentinel CubeSat spacecraft. The Pearl SBC, along with DDC’s flash memory, is baselined for use on multiple upcoming missions for both NASA and the DOD.

BioSentinel is a NASA space mission designed to study the effects of solar radiation on organisms. BioSentinel will be deployed as part of the first flight of the Space Launch System (SLS). SLS is the largest rocket ever developed, and will enable astronauts to explore destinations far into the solar system.

DDC’s 192 gigabit NAND flash provides the CubeSat spacecraft with compact, high density memory, along with the advantages that a 24-bit bus configuration provides, allowing the use of TMR (Triple Modular Redundancy) error correction, for seamless operation without failure. DDC’s NAND flash is radiation hardened with radiation mitigation RAD-PAK technology, offering spot shielding.

RAD-PAK enables DDC to deliver the latest commercially available microelectronics in a space qualified package, providing designers with a high performance space grade solution at a reduced cost. RAD-PAK-based solutions offer a total dose immunity of 100 krads or higher, and have been qualified by NASA, ESA, JAXA and thousands of missions for over 20 years without any flight failures.

Proven reliability

Hermetically sealed ceramic flat package with RAD-PAK radiation-hardened shielding.
RAD-PAK packaging technology has been qualified by NASA, ESA, JAXA and thousands of missions for over 20 years without any flight failures.

Optimised Performance

High density: Based on up to eight 32 Gb x8 NAND flash die (256 Gb), supports higher speed designs with less capacitance and fewer I/O's to drive.
Single Level Cell (SLC) Technology: Offers fast read and write capabilities and boot times, along with excellent endurance and reliability.

“We have worked on many space projects with NASA, and we are pleased that they continue to value the high reliability of our space products, along with the advanced functionality and performance that DDC is able to deliver, utilising our space proven and qualified RAD-PAK technology”, stated DDC Space Business Unit Manager, Dan Veenstra.
