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).
- Features:
- Comprehensive MIL-STD-1553 dual redundant Bus Controller (BC), Remote Terminal (RT), and Monitor Terminal (MT) with integrated bus transceivers, Memory, and Memory Management Unit (MMU)
- MIL-STD-1553B, Notice II RT
- Internal command illegalization with integrated bus transceivers in the RT mode
- 16-bit read/write time-tag with user-defined resolution
- Subaddress data buffering

- Flexible BC architecture designed to off-load the host computer
- Minor frame timing
- Efficient command block flow statements (Branch, Go To, Call)
- Status word polling
- Programmable retries
- Programmable interrupt architecture with automatic interrupt logging available in all modes
- Autonomous operation in all three modes of operation making it ideal for low cost remote terminals
