ESCRIPTION
:
Maxwell Technologies’ 28C256T high density 256k-bit
EEPROM microcircuit features a greater than 100 krad (Si)
total dose tolerance, depending upon space mission. The
28C256T is capable of in-system electrical byte and page pro-
grammability. It has a 64-Byte page programming function to
make its erase and write operations faster. It also features
data polling to indicate the completion of erase and program-
ming operations.
Maxwell Technologies' patented R

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.
