Description  
The AT68166H is a 16Mbit SRAM packaged in a hermetic Multi Chip Module  
(MCM) for space applications.  
The AT68166H MCM incorporates four 4Mbit AT60142H SRAM dice. It can be orga-  
nized as either one bank of 512Kx8, two banks of 512Kx16 or four banks of 512Kx8. It  
combines rad-hard capabilities, a latch-up threshold of 80MeV.cm²/mg, a Multiple Bit  
Upset immunity and a total dose tolerance of 300Krads, with a fast access time.  
The MCM packaging technology allows a reduction of the PCB area by 50% with a  
weight savings of 75% compared to four 4Mbit packages.  
Thanks to the small size of the 4Mbit SRAM die, Atmel has been able to accommo-  
date the assembly of the four dice on one side of the package which facilitates the  
power dissipation.  
The compatibility with other products allows designers to easily migrate to the Atmel  
AT68166H memory.  
The AT68166H is powered at 3.3V.  
The AT68166H is processed according to the test methods of the latest revision of the  
MIL-PRF-38535 or the ESCC 9000.
