Radiation-tolerant NOR Flash memory large enough for application programs or kernels introduced by Aeroflex

COLORADO SPRINGS, Colo., 20 Dec. 2011. Aeroflex Inc. in Colorado Springs, Colo., is introducing the UT8QNF8M8 64-megabit NOR Flash memory, a radiation-tolerant 3-volt memory organized as 8Mx8 or 4Mx16 for satellites and other space applications. The UT8QNF8M8 NOR Flash is a non-volatile solution that has memory capacity large enough to hold a typical application program or operating system kernel, Aeroflex officials say. Aeroflex is a wholly owned subsidiary of Aeroflex Holding Corp. (NYSE:ARX).

The UT8QNF8M8 NOR Flash device operates from one power supply voltage of 3.3 volts for read and write functions, and operate in temperatures from -55 to 105 degrees Celsius. The device is designed to be programmed in-system with 3.3-volt Vcc supply and can also be programmed in standard PROM programmers. The rad-hard device withstands total-dose radiation of 10 or 30 megarads, depending on the model.

"Radiation characterization has been completed and the UT8QNF8M8 will be offered at 10 and 30 krads(Si) with a goal of 50 krads(Si) and SEL immunity of 80MeV-cm2/mg," says Anthony Jordan, Aeroflex director-standard products. "During SEE testing only a soft reset was required to restore functionality to the device, no power cycle was needed."

The UT8QNF8M8 is offered in a 48-lead flatpack, Q and Q+ qualified and will be available to Standard Microcircuit Drawings. For more information contact Aeroflex online at
