SX Family FPGAs RadTolerant and HiRel
SX Family FPGAs RadTolerant and HiRel
General Description
The Actel RadTolerant (RT) and HiRel versions of the SX
Family of FPGAs offer many advantages for applications
such as commercial and military satellites, deep space
probes, and all types of military and high reliability
equipment.
The RT and HiRel versions are fully pin-compatible,
allowing designs to migrate across different applications
that may or may not have radiation requirements. Also,
the HiRel devices can be used as a low cost prototyping
tool for RT designs.
The programmable architecture of these devices offers
high performance, design flexibility, and fast and
inexpensive prototyping—all without the expense of test
vectors, NRE charges, long lead times, and schedule and
cost penalties for design modifications required by ASIC
devices.
Radiation Survivability
Total dose results are summarized in two ways. First, by
the maximum total dose level that is reached when the
parts fail to meet a device specification but remain
functional. For Actel FPGAs, the parameter that exceeds
the specification first is I
CC
, the standby supply current.
Second, by the maximum total dose that is reached prior
to the functional failure of the device.
The RTSX devices have varying total dose radiation
survivability. The ability of these devices to survive
radiation effects is both device- and lot-dependent. The
customer must evaluate and determine the applicability
of these devices to their specific design and
environmental requirements.
Actel will provide total dose radiation testing data along
with the test data on each pedigreed lot available for
sale. These reports are available on the Actel website, or
you can contact your local sales representative to receive
a copy. A listing of available lots and devices will also be
provided. These results are only provided for reference
and for customer information.
For a radiation performance summary, see
Radiation
Performance of Actel Products.
This summary will also
show single event upset (SEU) and single event latch-up
(SEL) testing that has been performed on Actel FPGAs.
Device Description
The RT54SX16 and A54SX16 devices have 16,000
available gates and up to 179 I/Os. The RT54SX32 and
A54SX32 have 32,000 available gates and up to 228 I/Os.
All of these devices support JTAG boundary scan
testability.
All of these devices are available in Ceramic Quad Flat
Pack (CQFP) packaging, with 208-pin and 256-pin
versions. The 256-pin version offers the user the highest
I/O capability, while the 208-pin version offers pin
compatibility with the commercial Plastic Quad Flat Pack
(PQFP-208). This compatibility allows the user to
prototype using the very low cost plastic package and
then switch to the ceramic package for production. For
more information on plastic packages, refer to the
54SX
Family FPGAs
datasheet.
The A54SX16 and A54SX32 devices are manufactured
using a 0.35 µ technology at the Chartered
Semiconductor facility in Singapore. These devices offer
the highest speed performance available in FPGAs today.
The RT54SX16 and RT54SX32 devices are manufactured
using a 0.6 µ technology at the Matsushita (MEC) facility
in Japan. These devices offer levels of radiation
survivability far in excess of typical CMOS devices.
QML Certification
Actel has achieved full QML certification, demonstrating
that quality management, procedures, processes, and
controls are in place and comply with MIL-PRF-38535, the
performance specification used by the Department of
Defense for monolithic integrated circuits. QML
certification is a good example of Actel's commitment to
supplying the highest quality products for all types of
high-reliability, military, and space applications.
Many suppliers of microelectronics components have
implemented QML as their primary worldwide business
system. Appropriate use of this system not only helps in
the implementation of advanced technologies, but also
allows for quality, reliable, and cost-effective logistics
support throughout the life cycles of QML products.
