ESCRIPTION
:
Maxwell Technologies' 27C512T high density 512-Kilobit one-
time programmable electrically programmable read only mem-
ory microcircuit features a greater than 100 krad (Si) total
dose tolerance, depending upon space mission. The 27C512T
features fast address times and low power dissipation. The
27C512T offers high speed programming using page pro-
gramming mode.
Maxwell Technologies' patented R
AD
-P
AK
packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age. It eliminates the need for box shielding while providing
the required radiation shielding for a lifetime in orbit or space
mission. In a GEO orbit, R
AD
-P
AK
provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.
