DESCRIPTION
DDC’s BU-61559 series of Advanced Integrated Mux Hybrids with
enhanced RT Features (AIM-HY’er) comprise a complete interface
between a microprocessor and a MIL-STD-1553B Notice 2 bus,
implementing Bus Controller (BC), Remote Terminal (RT), and
Monitor Terminal (MT) modes. Packaged in a single 78-pin DIP or flat
package, the BU-61559 series contains dual low-power transceivers
and encoder/decoders, complete BC/RT/MT protocol logic, memory
management and interrupt logic, 8K x 16 of shared static RAM, and
a direct, buffered interface to a host processor bus.
• Internal Command Illegalization
• MIL-PRF-38534 Processing Available
• Transmitter Inhibit Control for
Individual Bus Channels
The BU-61559 includes a number of advanced features that support
MIL-STD-1553B Notice 2 and STANAG 3838. Other salient features
of the BU-61559 serve to provide the benefits of reduced board space
requirements, enhanced software flexibility, and reduced host proces-
sor overhead.
The BU-61559 contains internal address latches and bidirectional
data buffers to provide a direct interface to a host processor bus.
Alternatively, the buffers may be operated in a fully transparent mode
in order to interface to up to 64K words of external shared RAM
and/or connect directly to a component set supporting the 20 MHz
STANAG 3910 bus.
The memory management scheme for RT mode provides an option
for separation of broadcast data, in compliance with 1553B Notice 2.
A circular buffer option for RT message data blocks offloads the host
processor for bulk data transfer applications.
The BU-61559 series hybrids operate over the full military tempera-
ture range of -55 to +125°C and MIL-PRF-38534 processing is avail-
able. The hybrids are ideal for demanding military and industrial
microprocessor-to-1553 applications.
