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

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

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

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.
