The monolithic CMOS UT1553 BCRTMP provides the system designer with an intelligent solution to MIL-STD-1553 multiplexed serial data bus design problems. The UT1553 BCRTMP is a single-chip device that implements two of the three defined MIL-STD-1553 functions - Bus Controller and Remote Terminal - and is flexible enough to conform to many of the MIL-STD-1553 “industry standards” created between and including releases of MIL-STD-1553A and MIL-STD-1553B. Designed to reduce host CPU overhead, the BCRTMP’s powerful state machines automatically execute message  ransfers, provide interrupts, and generate status information.
