All Silicon IP

Overview

The 1553-BC/RT/MT IP core implements a serial link controller enabling the development of Bus Controllers (BC), Remote Terminals (RT), and Monitor Terminals (MT) compliant with the Department of Defense MIL-STD-1553B standard.

Field-proven in many civilian and military avionics systems and optionally accompanied by a DO-254 certification package, the core is highly reliable and ready for aviation applications.

The core can operate as a Bus Controller, Remote Terminal, and Monitor Terminal at the same time. The BC and RT modules can also be disabled at run time, or at synthesis time to reduce silicon requirements. The Monitor Terminal provides 1553 Bus Monitor (BM) functions within the core. It is available under all configurations, and can be enabled or disabled at run time.

The 1553-BC/RT/MT is suitable for the implementation of MIL-STD-1553B Bus Controllers (BC), Remote Terminals (RT), and Bus Monitors (BM) in avionics systems.

The 1553-BC/RT/MT is designed to enable flexible message scheduling, monitoring, and filtering for all types of traffic in different bus architectures and with minimum overhead for the host processor. Messages are conveyed to/from the host via shared memory space organized in 16-bit words, and configure the core via its 16-bit wide register interface.

Benefits

Compatibility with popular IC devices enables the core to work with industry-standard drivers and software applications. Special versions are available for drop-in replacement of legacy ICs.

Applications

The 1553-BC/RT/MT is suitable for the implementation of MIL-STD-1553B Bus Controllers (BC), Remote Terminals (RT), and Bus Monitors (BM) in avionics systems.
