256 Mb SDRAM  
8-Meg X 8-Bit X 4-Banks  
FEATURES:  
DESCRIPTION:  
• 256 Megabit ( 8-Meg X 8-Bit X 4-Banks)  
• RAD-PA 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  
SRAMs 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  
TH  
• 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 RAD-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, RAD-PAK® provides greater than 100 krads(Si)  
radiation dose tolerance. This product is available with  
screening up to Maxwell Technologies self-defined Class  
K.  
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 RAD-PAK® Flat Package
