DESCRIPTION:

Maxwell Technologies’ 27C1512T high density 512K OneTime
Programmable Electrically Programmable Read Only Memory
multi-chip module (MCM) features a greater than 100 krad (Si)
total dose tolerance, depending upon space mission. The
27C1512T features fast address times and low power dissipa­tion. The 27C1512T offers high speed programming using
page programming mode. The 27C1512T is offered in
JEDEC-Standard Byte-Wide EPROM pinouts, which allows
socket replacement with flash memory and mask ROMs.

Maxwell Technologies' patented R
ogy incorporates radiation shielding in the microcircuit pack­age. 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 K.
