Rad Hard 512Kb (32K x 16-bit) OTP EPROM MCM Memory

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


Part Number(s): 27C1512T

DDC's 27C1512T high density 512K One Time 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.

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 DDC's self-defined Class K.
