Description

The 48SD1616 Synchronous Dynamic Random Access Memory (SDRAM) is ideally suited for space applications requiring high performance computing and high density memory storage. As microprocessors increase in speed and demand for higher density memory escalates, SDRAM has proven to be the ultimate solution by providing bit-counts up to 256 Mega Bits and speeds up to 133 Megahertz. SDRAMs represent a significant advantage in memory technology over traditional SRAMs including the ability to burst data synchronously at high rates with automatic column-address generation, the ability to interleave between banks masking precharge time, and the ability to randomly change column address during each clock cycle.

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 typical GEO orbit, RAD-PAK® provides greater than 100 krad (Si) radiation dose tolerance. This product is available with screening up to Class K.
