Rad Hard 1 Megabit (128K x 8-Bit) - OTP EPROM Memory

Discontinued Product. Please contact the factory for the latest replacement.


Part Number(s): 27C010T

DDC’s 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 dissipation. The 27C010T offers high speed programming using page programming mode. The 27C010T is offered in JEDEC-Standard Byte-Wide EPROM pinouts, which allows socket replacement with Flash Memory and Mask ROMs.

DDC’s 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.
