Maxwell Technologies’ 89C1632 high-performance 16 Megabit Multi-Chip Module (MCM) Static Random Access Memory features a greater than 100 krad (Si) total dose tolerance, depending upon space mission. The four 4-Megabyte SRAM die and bypass capacitors are incorporated into a high-reliable hermetic quad flat-pack ceramic package.
With high-performance silicon-gate CMOS technology, the 89C1632 reduces power consumption and eliminates the need for external clocks or timing strobes. It is equipped with output enable (OE) and four byte enable (CS1 - CS4) inputs to allow greater system flexibility. When OE input is high, the output is forced to high impedance.
About RAD-PAK® Technology
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.
