ESCRIPTION
:
Maxwell Technologies’ 28LV011 high density, 3.3V, 1 Megabit
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 pro-
grammability. 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 pin, in addi-
tion to noise protection on the WE signal and write inhibit on
power on and off. Meanwhile, software data protection is
implemented using the JEDEC-optional Standard algorithm.
The 28LV011 is designed for high reliability in the most
demanding space applications.
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.
Note:The recommended form of data protection during power
on/off is to hold the RES pin to V
SS
during power up and power
down. This may be accompanied by connecting the RES pin
to the CPU reset line. Failure to provide adequate protection
during power on/off may result in lost or modified data.
