ESCRIPTION
:
Maxwell Technologies’ 28LV011 high-density 1 Megabit (128K
x 8-Bit) EEPROM microcircuit features a greater than 100
krad (Si) total dose tolerance, depending upon space mission.
The 28LV011 is capable of in-system electrical byte and page
programmability. It has a 128-byte page programming function
to make its erase and write operations faster. It also features
data polling and a Ready/Busy signal to indicate the comple-
tion of erase and programming operations. In the 28LV011,
hardware data protection is provided with the RES , in addition
to noise protection on the WE signal and write inhibit on power
on and off. Software data protection is implemented using the
JEDEC optional standard algorithm.
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 Maxwell Technologies’ self-defined Class
S.
