DESCRIPTION:

• Four 512k x 8 SRAM die

• R^AD-PAK® technology hardens against natural space radia-

tion technology

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 enable (CS1 - CS4) inputs to allow

greater system flexibility. When OE input is high, the output is

forced to high impedance.

• Total dose hardness:

- > 100 krad (Si), depending upon space mission

• Excellent Single Event Effects:

- SEL > 101MeV-cm²/mg

- SEU threshold = 3 MeV-cm²/mg

- SEU saturated cross section: 8E-9 cm²/bit

• Package: 68-pin quad flat package

• Completely static memory - no clock or timing strobe

required

• Internal bypass capacitor

• High-speed silicon-gate CMOS technology

• 3.3 V ± 10% power supply

• Equal address and chip enable access times

• Three-state outputs

Maxwell Technologies' patented R^AD-PAK® packaging technol-

ogy incorporates radiation shielding in the microcircuit pack-

age. In a GEO orbit, R^AD-PAK® packaging provides greater

than 100 krad(Si) total radiation dose tolerance, dependent

upon space mission. It eliminates the need for box shielding

while providing the required radiation shielding for a lifetime in

orbit or a space mission. This product is available in with

screening up to Maxwell Technologies self-defined Class K.

• All inputs and outputs are TTL compatible
