Maxwell Technologies’ 89LV1632 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-Megabit 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 89LV1632 reduces power consumption and eliminates the need for external clocks or timing strobes.
The 89LV1632 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.
