Digital and Mixed Signal ASIC Foundry Radiation
AssessmentsTask 04-052
Description
Benefits
The prime benefit is providing NASA reliable
techniques and selection criteria for ASICs.
Albeit, FPGAs are becoming of wider spread use,
there are still a large number of applications
that require ASICs (digital or mixed signal)
for performance and mixed signal issues. By
providing a reference list of available foundry
radiation data by process and updating by test
on a yearly/bi-yearly basis (2 to 4 per year),
higher radiation reliability ASICs will be
inserted into NASA systems.

Application specific integrated circuits (ASICs)
are commonly used in both spacecraft subsystems
as well as science instruments. This
includes digital, analog, and mixed signal
devices. These devices provide a savings in
volume, power, and weight versus discrete designs
and often provide a performance benefit for
science accuracy or bandwidth. This task is in
combination with a non-radiation task
assessing ASIC foundries. The first step is to
determine what radiation evaluation work has been
done on current ASIC foundries both within NASA
and without and to determine adequacy of
radiation qualification procedures (test chips
and/or structures). Once this is done, a
round-robin multi-agency approach to provide
periodic radiation assessments of COTS foundries
will be developed (cost-sharing)..
Deliverables

• BOK of existing radiation qualification
  procedures (JPL)
• Database of existing radiation data by commercial
  foundry (GSFC)
• Selection guide for COTS foundries (radiation
  issues BOK) JPL/GSFC
• Test reports on foundry performance (updates to
  database) (GSFC - digital, JPL mixed signal)
