DESCRIPTION
The BU-65142 Series is a Hi-Rel
radiation tolerent complete dual
redundant MIL-STD-1553 Remote
Terminal Unit (RTU). The device is
based upon two DDC custom ICs,
which includes two monolithic bi-
polar low power transceivers and
one RiCmos protocol containing
data buffers and timing control logic.
It supports all 13 mode codes for dual
redundant operation, any combina-
tion of which can be illegalized.
Parallel data transfers are accom-
plished with a DMA type handshak-
ing, compatible with most CPU
types. Data transfers to/from mem-
ory are simplified by the latched
command word and word count out-
puts.
Error detection and recovery are
enhanced by BU-65142 Series spe-
cial features. A 14-bit built-in-test
word register stores RTU information,
and sends it to the Bus Controller in
response to the Mode Command
Transmit Bit Word. The BU-65142
Series performs continuous on-line
wraparound self-test, and provides
four error flags to the host CPU.
Inputs are provided for host CPU con-
trol of 6 bits of the RTU Status Word.
Its integrated hermetic package,
-55°C to +125°C operating tempera-
ture range, and complete RTU opera-
tion make the BU-65142 ideal for
MIL-STD-1553 applications requiring
hardware or microprocessor subsys-
tems.
