Description

Maxwell Technologies' Synchronous Dynamic Random Access Memory (SDRAM) 48SD3208 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 mem- ory escalates, SDRAM 48SD3208 has proven to be the ultimate solution by providing bit-counts up to 256 Mega Bits and speeds up to 100 Megahertz. SDRAMs 48SD3208 represent a sig- nificant 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 pre- charge time.

Maxwell Technologies' patented RAD-PAK(R) packaging technology about 48SD3208 incorporates radiation shielding in the micro-circuit package. It eliminates the need for box shielding for a lifetime in orbit or space mission. In a typical GEO orbit, RAD-PAK(R) provides greater than 100 krads(Si) radiation dose tolerance. This 48SD3208 is available with screening up to Maxwell Technologies self-defined Class K.
