MIL-STD-1553B Databus

UT69151 SµMMIT™ XTE

Overview

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™ XTE contains all the functions of the SµMMIT DXE device, but offers internal memory and a Memory Management Unit (MMU).
