ESCRIPTION
:
Maxwell Technologies’ 32C408B high-speed 4 Megabit SRAM
mcrocircuit features a greater than 100 krad (Si) total dose
tolerance, depending upon space mssion. Using R
AD
-P
AK
packaging technology, the 32C408B realizes higher density,
higher performance and lower power consumption, and is well
suited for high-speed systemapplication. Its fully static design
elimnates the need for external clocks, while the CMOS cir-
cuitry reduces power consumption and provides higher reli-
ability. The 32C408B is equipped with eight common input/
output lines, chip select and output enable, allowing for
greater systemflexibility and elimnating bus contention.
Maxwell Technologies' patented R
AD
-P
AK
packaging technol-
ogy incorporates radiation shielding in the mcrocircuit pack-
age. In a GEO orbit, R
AD
-P
AK
can provides true greater than
100 krad (Si) total radiation dose tolerance; dependent upon
space mssion. The patented radiation-hardened R
AD
-P
AK
technology incorporates radiation shielding in the mcrocircuit
package. It elimnates the need for box shielding while provid-
ing the required radiation shielding for a lifetime in orbit or a
space mssion. This product is available with packaging and
screening up to Class S.
