Single-Chip Solution of MIL-STD-1553A and MIL-STD-1553B Data Communications 872488

Several versions of the Avionics Time-Multiplexed 1553 serial communication standards are in use. Solutions available for some 1553 protocols are often large and complex, and are not designed to be usable for more than one protocol. This paper describes the basic differences among the 1553 protocols, and discusses the system and architectural aspects of a single-chip solution that meet all requirements for a complete dual-redundant Bus Controller and Remote Terminal (BCRT) for the following 1553 standards: MIL-STD-1553A, MIL-STD-1553B, McDonnell Douglas A3818, McDonnell Douglas A5232, McDonnell Douglas A5690, and Grumman Aerospace SP-G-151A. Easily integrated into a variety of system architectures and requiring little CPU overhead, the single-chip device contains all memory management, error logging, and a simple-to-use processor interface.
