BU-63825(925):
DESCRIPTION
The BU-63825/925 BC/RT/MT Sp’ACE-II and BU-63705 Space-RT-II series of MIL-STD-1553 terminals continues Data
Device Corporation’s (DDC’s) commitment to producing hybrids with enhanced processing and screening for space
borne, radiation and Hi-Rel applications. Both terminals are designed specifically to be hardware and software
compatible, direct drop-in replacements for the equivalent Sp’ACE and Space RT series.
The BU-63825/925 Sp’ACE-II is a complete integrated interface between a 1553 bus and a host processor, and
replaces the BU-61582/83 Sp’ACE ( Space Advanced Communication Engine) pin-for-pin with the same 1.9 square
inch package.
The BU-63705 Space RT-II is a terminal for simple, non-CPU based applications, and shares the same 3.78 square inch
package as BU-65142 Space RT, which it replaces.
APPLICATIONS
The new generation of Sp’ACE-II and Space-RT-II terminals are designed for applications requiring the highest levels
of reliability and radiation tolerance*, including such platforms as launch vehicles, satellites and the International
Space Station.
DESIGN
The manufacturing of hybrids for space applications involves enhancements in the area of layout design, processing
and screening. The principle goal of the hybrid mechanical design is to improve the ease of wire bonding and
inspection. All of DDC's space grade terminals utilize ceramic packaging. Ceramic packages eliminate the potential
hermeticity problems associated with the glass beads of KOVAR (metal) packages. In addition, ceramic packages
facilitate improved thermal properties and feature reduced weight and lower cost.

RADIATION HARDNESS*
In addition to the screening process, DDC pays
particular attention to the technologies used in the
design of space grade 1553 components. DDC's 1553
series of products combine Bipolar (-15V & -12V) and
BiCMOS (+5V) transceivers along with specially
designed ASICs (HX2000 Series, 0.65 micron RICMOS™ IV
SOI process) and SRAM (HX6256, 0.75 micron RICMOS™
IV SOI process) fabricated by Honeywell Solid-State
Electronics Center (HSSEC). This results in devices with a
minimum total dose of 100 KRAD (Si) with Latch-up
immunity to a maximum radiation hardened total dose
of 1 MRAD (Si). The Sp'ACE II (BU-63825/925) has a Single
Event Upset (SEU) rate of 2.56 x 10-5 errors/device-day
and Linear Energy Transfer (LET) threshold of 63
MeV/cm2/mg.
• Radiographic (X-ray) Inspection (Optional)
• 320-hour burn-in (Standard) {burn-in for Class
H devices is 160 hours}
• Destructive Physical Analysis (DPA) testing
(Optional)
DDC offers other optional services such as Pre-Cap Source
Inspection, One Lot Date Code, Solder Dip, Variables Test
Data, Element Evaluation/SEM Inspection, Configuration
Control, and Program Management. Both the Sp'ACE II
(BU-63825/925) and Space-RT-II (BU-63705) are available to
SMD (Standard Military Drawings), 5962-96887 and 5962-89798,
respectively.
THE TRUE HI-REL SOLUTION
By combining DDC’S long history of producing high reliability
microelectronics with its Class K DSCC Certification, DDC’S
MIL-STD-1553 space level products become the true Hi-Rel
solution. DDC’s ability to integrate a full MIL-STD-1553 space-
grade terminal into a single package results in cost-effective,
small size, low power, high performance and high reliability
solutions for all MIL-STD-1553 space level requirements. These
devices are suitable for space applications, including Launch
Vehicles, Military Satellites, Research Satellites, the
International Space Station, and the Commercial
Telecommunication Satellite arena.

HYBRID SCREENING FOR HIGH RELIABILITY
Visual screening for space grade hybrids includes
rigorous inspection for damaged die and wires, stray parti-
cles, and contamination. Additional screening
procedures for space hybrids include:
• 100% Non-destructive wire bond pull (Standard)
• Condition "A" Visual Inspection (Standard)
• Particle Impact Noise Detection (PIND) testing
with the use of getter material (Optional)
