Aeroflex Colorado Springs' UT9Q512 and the UT9Q512K32 have been replaced with the UT9Q512E and the UT9Q512K32E. See the Aeroflex Customer Notification Letter dated 4-07 and 8-07 below for the improvements/differences. We also offer RadHard Memories with higher radiation levels (visit www.aeroflex.com/RadHardSRAM). For questions, please call 800-645-8862. Aeroflex Colorado Springs was again awarded the Northrop Grumman Space Technology 2007 Gold Supplier Award.
