ESCRIPTION
:
Maxwell Technologies’ 28C010T high-density 1 Megabit
(128K x 8-Bit) EEPROM microcircuit features a greater than
100 krad (Si) total dose tolerance, depending upon space mis-
sion. The 28C010T 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
completion of erase and programming operations. In the
28C010T, hardware data protection is provided with the RES
pin, in addition to noise protection on the WE signal and write
inhibit on power on and off. Software data protection is imple-
mented using the JEDEC optional standard algorithm.
Maxwell Technologies' patented R

® 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

® provides greater than 100
krad(Si) radiation dose tolerance. This product is available
with screening up to Class S.
