DESCRIPTION:

Maxwell Technologies’ 89C1632 high-performance 16 Mega-

bit 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-perfor-

mance 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.

Maxwell Technologies' patented RAD-PAK® packaging technol-

ogy incorporates radiation shielding in the microcircuit pack-

age. In a GEO orbit, RAD-PAK provides true greater than 100

krad (Si) total radiation dose tolerance, dependent upon space

mission. It eliminates the need for box shielding while provid-

ing the required radiation shielding for a lifetime in orbit or a

space mission. This product is available in Class H or Class K

packaging and screening.
