BUS-61553
Advanced
Integrated Mux (AIM) Hybrid is a
complete
MIL-STD-1553
Bus
Controller (BC), Remote Terminal
Unit (RTU), and Bus Monitor (MT)
device. Packaged in a single 78-pin
DIP package, the BUS-61553 con-
tains dual low-power transceivers,
complete BC/RT/MT protocol logic, a
MIL-STD-1553-to-host interface unit
and 8K x 16 RAM.
Using an industry standard dual
transceiver and standard status and
control signals, the BUS-61553 sim-
plifies system integration at both the
MIL-STD-1553 and host processor
interface levels.
All 1553 operations are controlled
through the CPU access to the
shared 8K x 16 RAM. To ensure
maximum design flexibility, memory
control lines are provided for attach-
ing external RAM to the BUS-61553
address and data buses and for dis-
abling internal memory; the total
combined memory space can be
expanded to 64K x 16. All 1553 trans-
fers are entirely memory-mapped;
thus the CPU interface requires
minimal hardware and/or software
support.
The BUS-61553 operates over the
full military -55°C to +125°C temper-
ature range. Available screened to
MIL-PRF-38534, the BUS-61553 is
ideal for demanding military and
industrial
microprocessor-to-1553
interface applications.
