ESCRIPTION
:
Maxwell Technologies’ 89LV1632 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-Megabit 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 89LV1632 reduces
power consumption and eliminates the need for external
clocks or timing strobes. It is equipped with output enable
(OE) and four byte chip enables (CS1 - CS4) inputs to allow
greater system flexibility. When OE input is high, the output is
forced to high impedance.
Maxwell Technologies' patented R
AD
-P
AK
® packaging technol-
ogy incorporates radiation shielding in the microcircuit pack-
age.It eliminates the need for box shielding while providing the
required radiation shielding for a lifetime in orbit or a space
mission. In a GEO orbit, R
AD
-P
AK
® packaging provides greater
than 100 krad(Si) total radiation dose tolerance. This product
is available with screening up to Maxwell Technologies self-
defined Class K.
