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 MILSTD-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 UTM
