ESCRIPTION

DDC’s 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-Megabit SRAM die and

bypass capacitors are incorporated into a high-reliable her-

metic 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 flexi-

bility. When OE input is high, the output is forced to high

impedance.

DDC’s patented R

-P

® packaging technology incorporates

radiation shielding in the microcircuit package. In a GEO orbit,

-P

provides true greater than 100 krad (Si) total radiation

dose tolerance, dependent upon space mission. It eliminates

the need for box shielding while providing the required radia-

tion shielding for a lifetime in orbit or a space mission. This

product is available with screening up to DDC’s self-defined

Class K.
