QCOTS 4M 5V Customer letter - die inv exhausted (3/06)

March 3, 2006
Dear Customer:
The purpose of this letter is to update you on the die inventory of our 5V 4M SRAM Quantified
Commercial-Off-The Shelf (QCOTSTM) used in the UT9Q512K8 and UT9Q512K32 products. In
June 2005 we announced the finite supply of the commercial die source would exhaust in 6 to 8
months. The die inventory has exhausted. A very small amount of packaged units remain in
finished goods inventory. The shielded 36-lead CFP is now obsolete.
Products affected by the die are listed below.

The 36-lead Shielded CFP has reached End of Life (EOL).
As an alternative SRAM solution, Aeroflex offers a 3-volt (3V) 4M and 16M SRAM,
UT8Q512K8 and UT8Q512K32 QCOTS SRAM. Data Sheets for the 3V QCOTS SRAM
solutions can be found at www.aeroflex.com/QCOTS.

The 36-lead Shielded CFP has reached End of Life (EOL).
It will be added as devices 5 and 6 to the SMD.
It will be added as devices 3 and 4 to the SMD.
Aeroflex continues to make progress in the development of a 5V 4M replacement based on
existing Aeroflex development memory technology. The 5V replacement product would be
available in late-2006 to a QML Q and V level. At this time, we continue to project the 5V 4M
SRAM will be a functional replacement. The following AC and DC Electrical Characteristic
differences have been identified.

Aeroflex packaging engineers have identified fit and form differences in both the 4M and 16M
packages. A comparison of the package differences is shown below. For application questions
regarding fit, form, and function of either the current 3V QCOTS SRAM or the new 5V SRAM
replacement, please contact Don Cooper at (719) 594-8148 or e-mail [email protected].
