FEATURES:

DESCRIPTION:

• 256 Megabit ( 16-Meg X 4-Bit X 4-Banks)

• RAD-PAK® radiation-hardened against natural space

radiation

Maxwell Technologies’ Synchronous Dynamic Random

Access Memory (SDRAM) is ideally suited for space

applications requiring high performance computing and

high density memory storage. As microprocessors

increase in speed and demand for higher density mem-

ory escalates, SDRAM has proven to be the ultimate

solution by providing bit-counts up to 256 Mega Bits and

speeds up to 100 Megahertz. SDRAMs represent a sig-

nificant advantage in memory technology over traditional

DRAMs including the ability to burst data synchronously

at high rates with automatic column-address generation,

the ability to interleave between banks masking pre-

charge time.

• Total Dose Hardness:

>100 krad (Si), depending upon space mission

• Excellent Single Event Effects:

SEL > 85 MeV/mg/cm²@ 25°C

• JEDEC Standard 3.3V Power Supply

• Operating Current: 115 mA

• Clock Frequency: 100 MHz Operation

• Operating tremperature: -55 to +125 °C

• Auto Refresh

• Single pulsed RAS

• 2 Burst Sequence variations

Sequential (BL =1/2/4/8)

Maxwell Technologies’ patented R^AD-PAK® packaging

technology incorporates radiation shielding in the micro-

circuit package. It eliminates the need for box shielding

for a lifetime in orbit or space mission. In a typical GEO

orbit, R^AD-PAK® provides greater than 100 krads(Si)

radiation dose tolerance. This product is available with

screening up to Maxwell Technologies self-defined Class

Interleave (BL = 1/2/4/8)

• Programmable CAS latency: 2/3

• Power Down and Clock Suspend Modes

• LVTTL Compatible Inputs and Outputs

• Package: 72-Pin R^AD-PAK® Flat Package
