MIL-STD-1553 Remote Terminal Design Example Using a Zilog 8-bit MCU |
|
|
|
05/16/2008
|
|
A description of a MIL-STD-1553 Remote Terminal (RT) design using the Holt HI-6110 Message Processor product and a simple, commercial Zilog Z8F6422 8-bit microcontroller. It provides an overview of the hardware and software principles of a working design, including schematic diagrams and program flowcharts. This can be used for evalution of the HI-6110, and may be a suitable design basis for some applications. The evaluation board has the following features:
- Two 1553 bus interfaces, transformer- or direct-coupled
- Signal headers for connecting a logic analyzer
- Status LEDs, buttons for board reset and test sequencing
- DIP switch for selecting RT address and 1553 operating mode
- Serial port for an optional computer interface
- Microcontroller JTAG header for Zilog software debug
- Self-contained 3.3V power supply

Application Note: MIL-STD-1553 Remote Terminal Using SRAM for Host Interface |
|
|
|
11/19/2007
|
|
This application note describes design methods for a dual redundant MIL-STD-1553 Remote Terminal (RT) based on the HI-6110 Message Processor IC. This note is built on the working example resented in AN-530. It shows how to use shared static RAM as the primary interface to an external host, aided by a small
complement of I/O signals for option selection, status reporting and interrupt generation and acknowledgment.
Shared RAM also contains virtual registers for configuration and operating parameters, and fully programmable buffer space for subaddress and mode code commands. A wide range of settings are available in software so the user can tailor RT behavior to meet application requirements. |
