Description

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/Busysignal to indicate the comple-tion of erase and programming operations. In the 28LV011,hardware data protection is provided with the RESpin, 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 RAD-PAK® packaging technol-ogy incorporates radiation shielding in the microcircuit pack-age.  28LV011 eliminates the need for box shielding while providing the required radiation shielding for a lifetime in orbit or space mission.  In a GEO orbit, RAD-PAK® 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 RESpin to VSS 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.
