Frequently Asked
Questions
Q. Please tell us about your space computer/processor
products-do you have several products?
A. Yes, Space Micro offers both
the Proton 100K and Proton
200K rad hard single board computers for space. Our technology roadmap has even
more advanced versions (Proton 300k and 400k) planned for the future.
Q. How do you harden the COTS parts to the effects of
space radiation?
A. Space Micro is able to leverage state of the art
commercial processors by application of our patent pending TTMR SEU mitigation.
In addition, we apply H-core technology to mitigate SEFI.
Q. What is a typical SEU error rate for the Proton-series
computers?
A. SEU error rate for the industry standard Adams 90% GEO
is 1E –4 errors/day.
Q. What is typical power dissipation of both Proton 100K
and Proton 200K?
A. Typical SBC power dissipation operating at full speed
is 7-9 watts for Proton 100K and 4-7 watts for the Proton 200K.
Q. Does Space Micro also offer radiation hardened ICs?
A. Yes, Space Micro is developing several rad hard ICs
for the space market. These include: Rad hard error correction IC, Rad hard
level shifter, and Rad hard H-core IC.
Q. What semiconductor foundries do you use?
A. We use several qualified COTS IC foundries. The
selection is based on the performance requirements of the chip. Among our
foundries are AMI, TSMC, Maxim, Peregrine, and IBM (trusted foundry).
Q. What form factors are available for your SBCs for
space?
A. We offer SBCs in a variety of form factors including
3U, 6U, and variation on PCI-104. Virtually any size board is available for custom application
with a configuration charge.
Q. Do your products have heritage or space flight
qualification?
A. Our products have been delivered for space programs,
but have not yet flown. The first flight heritage is scheduled for December 2006 on TacSat II.
Q. What new technologies are in development at Space
Micro?
A. We continue to innovate with new technologies such as
laser comm. Error correction techniques, reconfigurable analog, encryption
technology, and signal processing node electronics.
Q. What is the background and expertise of Space Micro
management team?
A. Our management team has over 60 years of relevancy
experience in the space electronics community at Northrop, SAIC, Space
Electronics Inc, Maxwell, prior to founding Space Micro Inc. in 2002.
