Description

Maxwell Technologies’ 27C256T high density 256-Kilobit onetime programmable electrically programmable read only memory microcircuit features a greater than 100 krad (Si) total dose tolerance, depending upon space mission.

The 27C256T features fast address times and low power dissipation. The 27C256T offers high speed programming using page programming mode.

Maxwell Technologies' patented RAD-PAK® packaging technology 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, RAD PAK® provides greater than 100 krad (Si) radiation dose tolerance. This product is available
with screening up to Class S.
