The Defense Logistics Agency Land and Maritime (DLAM) has certified Infineon Technologies’ radiation-hardened 512 Mbit QSPI NOR Flash memory for space and harsh environment applications using QML-V and QML-P.
The U.S. government’s highest reliability standard for microcircuits, the QML certification, certifies that the device will function reliably even in the most trying circumstances. For the space industry, this makes the memory device the first and only QML-qualified radiation-hardened NOR flash memory.
For usage with space-qualified FPGAs and multi-core CPUs, the flash memory offers the best density, radiation, and single-event effects (SEE) performance known in a fully QML-qualified non-volatile memory. It also has a fast 133 MHz quad serial peripheral interface (QSPI).
The device makes use of Infineon’s well-proven SONOS (silicon-oxide-nitride-oxide-silicon) technology, which combines superior radiation performance with high density and speed. As a result, the device can operate up to 30% faster than alternatives with lower densities. Additionally, the technology allows for data retention for up to 10 years and a lifespan of up to 10,000 P/E cycles.
Furthermore, rapid data transfer rates for space-grade FPGAs and processors are offered by the 133 MHz QSPI interface.
There is a ceramic QFP package (QML-V) that takes up 1″ x 1″ of board space, and a smaller plastic TQFP package (QML-P) that has a 0.5″ x 0.8″ footprint. Furthermore, the QML-V/P with DLAM certification satisfies the most demanding industrial requirements, and the device provides the maximum density and TID/SEE performance for space FPGA and multi-core processor boot code solutions.
With all of these qualities, the device is especially well-suited for storing boot code for space-qualified multi-core CPUs and configuration images for space-grade FPGAs.
Leadership Comments
“The introduction of our first QML-P certified product is further testament to our commitment to deliver highly reliable and high-performance memories for next-generation space requirements,” said Helmut Puchner, Vice President, Fellow, Aerospace and Defense, Infineon Technologies. “Our in-house developed SONOS technology is an ideal solution for radiation and power limited environments. Further higher density NOR Flash products as well as AI/ML targeted compute-in-memory solutions are already in progress to further utilize our SONOS technology in these highly critical satellite applications.”
