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™ RTE (Remote Terminal) is an interface device linking a MIL-STD-1553 serial data bus to a host microprocessor and/or subsystem. The device’s MIL-STD-1553 interface includes encoding/decoding logic, error detection, command recognition, DMA interface, control/ configuration registers, clock, and reset logic.
