FEATURES:

DESCRIPTION:

• RAD-PAK® Technology radiation-hardened against natural

space radiation

• 524,288 x 8 bit organization

Maxwell Technologies’ 33LV408 high-density 4 Megabit

SRAM microcircuit features a greater than 100 krad (Si) total

dose tolerance, depending upon space mission. Using Max-

well’s radiation-hardened R^AD-PAK® packaging technology, the

33LV408 realizes a high density, high performance, and low

power consumption. Its fully static design eliminates the need

for external clocks, while the CMOS circuitry reduces power

consumption and provides higher reliability. The 33LV408 is

equipped with eight common input/output lines, chip select

and output enable, allowing for greater system flexibility and

eliminating bus contention. The 33LV408 features the same

advanced 512K x 8-bit SRAM, high-speed, and low-power

demand as the commercial counterpart.

· Total dose hardness:

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

• Excellent Single Event Effect

· - SEL : > 101 MeV/mg/cm²

· - SEU_TH: = 3 MeV/mg/cm²

- SEU saturated cross section: 6E-9 cm²/bit

• Package:

- 32-Pin R^AD-PAK® flat pack

• Fast access time:

- 20, 25, 30 ns maximum times available

• Single 3.3V + 10% power supply

• Fully static operation

Maxwell Technologies' patented R^AD-PAK® 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 space

mission. In a GEO orbit, R^AD-PAK® provides greater than 100

krad (Si) radiation dose tolerance. This product is available

with screening up to Class S.

- No clock or refresh required

• Three state outputs

• TTL compatible inputs and outputs

• Low power:

- Standby: 60 mA (TTL); 10 mA (CMOS)

- Operation: 150 mA (20 ns); 140 mA (25 ns);

130 mA (30 ns)
