The Changes in Device Technology
• Besides increased availability, many changes have taken
place in
– Base technology,
– Device features, and,
– Packaging
• The table below highlights a few selected changes

The Challenge for Selecting ICs for Space
• Considerations since
the “old days”
– High reliability (and
radiation tolerant)
devices
• Now a very small market
percentage
– Commercial
“upscreening”
• Increasing in importance
• Measures reliability,
does not enhance
– System level
performance and risk
• Hardened “systems” not
devices
ASICs?
FPGAs?
Processor?
DSPs
Flash?
SDRAM?
System Designer
Trying to meet high-resolution
instrument requirements AND
long-life
SerDes?
ADCs?

IC Selection Requirements
• To begin the discussion, we shall review IC
selection from three distinct and often contrary
perspectives
– Performance,
– Programmatic, and,
– Reliability.
• Each of these will be considered in turn, however,
one must ponder all aspects as part of the
process
