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

Outline

• Semiconductors: The Evolution of ICs

– Availability and Technology

• IC Selection Requirements - three fields of

thought

– Technical – “The Good”

– Programmatic – “The Bad”

– Risk/Reliability – “The Ugly”

• Reliability and Radiation

• Radiation Perspective - Four methods of

selecting ICs for space systems

– Guaranteed hardness

– Historical ground-based radiation data

– Historical flight usage

– Unknown assurance

• Understanding Risk

– Risk trade space

• Example: ASICs and FPGA – sample selection

criteria

• Conclusions

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)
