FEATURES:  
DESCRIPTION:  
• 512k x 8-bit CMOS architecture  
• RAD-PAK® technology hardened against natural space radi-  
ation  
Maxwell Technologies’ 32C408B high-speed 4 Megabit SRAM  
microcircuit features a greater than 100 krad (Si) total dose  
tolerance, depending upon space mission. Using RAD-PAK®  
packaging technology, the 32C408B realizes higher density,  
higher performance and lower power consumption, and is well  
suited for high-speed system application. Its fully static design  
eliminates the need for external clocks, while the CMOS cir-  
cuitry reduces power consumption and provides higher reli-  
ability. The 32C408B is equipped with eight common input/  
output lines, chip select and output enable, allowing for  
greater system flexibility and eliminating bus contention.  
Total dose hardness:  
- > 100 krad (Si), depending upon space mission  
• Single event effect:  
- SEL : > 68 MeV/mg/cm2  
TH  
- SEUTH: < 3MeV/mg/cm2  
- SEU saturated cross section: 6E-9 cm2/bit  
• Package:  
-36 pin RAD-PAK® flat pack  
• Fast propagation time:  
-20, 25, 30 ns maximum access time  
• Single 5V + 10% power supply  
Low power dissipation:  
Maxwell Technologies' patented RAD-PAK packaging technol-  
ogy incorporates radiation shielding in the microcircuit pack-  
age. In a GEO orbit, RAD-PAK can provides true greater than  
100 krad (Si) total radiation dose tolerance; dependent upon  
space mission. The patented radiation-hardened RAD-PAK  
technology incorporates radiation shielding in the microcircuit  
package. It eliminates the need for box shielding while provid-  
ing the required radiation shielding for a lifetime in orbit or a  
space mission. This product is available with packaging and  
screening up to Class S.  
- Standby: 60mA (TTL); 10mA (CMOS)  
- Operating: 180 mA (20 ns); 170 mA (25 ns); 160 mA (30  
ns)  
TTL compatible inputs and outputs  
• Fully static operation  
- No clock or refresh required  
Three state outputs
