DESCRIPTION:
Maxwell Technologies’ 27C010T high density 1 Megabit
One-time Programmable Electrically Programmable Read
Only Memory microcircuit features a greater than 100 krad (Si)
total dose tolerance, depending upon space mission. The
27C010T features fast address times and low power dissipa-
tion. The 27C010T offers high speed programming using page
programming mode. The 27C010T is offered in JEDEC-Stan-
dard Byte-Wide EPROM pinouts, which allows socket replace-
ment with Flash Memory and Mask ROMs.
Maxwell Technologies' patented RAD-PAK® 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, RAD-PAK provides greater than 100
krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.
