IC and Component Selection for Space Systems – Presented by Kenneth A. LaBel

The Growth in IC Availability
• The semiconductor industry has seen an explosion in the
types and complexity of devices that are available over the
last several decades
– The commercial market drives features
• High density (memories)
• High performance (processors)
• Upgrade capability and time-to-market (FPGAs)
• Wireless (RF and mixed signal)
• Long battery life (Low-power CMOS)
Zilog Z80 Processor
circa 1978
8-bit processor
Intel 65nm Dual Core Pentium D Processor
circa 2007
Dual 64-bit processors
Integrated Cycling Bib
and MP3

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?
