Deriving its name from Serial, µ-coded, Monolithic, Multi-mode, Intelligent, Terminal, the monolithic SµMMIT™ family provides the system designer with an intelligent solution to MIL-STD-1553 multiplexed serial data bus design problems.
Each SµMMIT device is a single-chip that implements all three of the defined MIL-STD-1553 functions - Remote Terminal, Bus Controller, and Monitor. Operating either autonomously or with a tightly coupled host, the SµMMIT devices solve a wide range of MIL-STD-1553 interface problems.
The UT69151 SµMMIT™ DXE contains all the functions of the SµMMIT E device, but offers integrated bus transceivers and associated protocol at +5V operation.

The objective of this product advisory is to inform MIL-STD-1553 circuit designers of lessons learned during a residual voltage investigation and to offer some transformer selection recommendations to minimize residual voltage.
SPO-2015-PA-0001A
This amendment adds BTTC as an approved transformer supplier for optimal compatibility with the CAES 1553 Transceiver. The results of the BTTC compatability study are included. A final recommendation for leakage inductance screening limits is defined.
