IN TRODUCT ION
The UT1553 RTMP (figures 1 and 4) is a monolithic,
CMOS, VLSI integrated circuit that meets all requirements
for a dual-redundant MIL-STD-1553 Remote Terminal
interface. The RTMP’s advanced design supports both
MIL-STD-1553A and MIL-STD-1553B serial data bus
protocols, including differences in the status word response
time and bit definitions, providing the system designer a
single-chip solution to most Remote Terminal interface
requirements.
The UT1553 RTMP provides all requisite 1553 protocol and
data handling, 1553 message error checking, DMA
handshake and control signals, and comprehensive self-test
capabilities. The RTMP’s pointer-based, programmable
memory-mapping architecture permits the host to map 1553
message data anywhere in the 64K memory space. This
advanced memory mapping, along with the RTMP’s control
and status functions, minimize the host system’s 1553
interface overhead.
The UT1553 RTMP is a member of UTMC’s complete
family of high-reliability monolithic MIL-STD-1553
interface products.
