The 3.3V CMOS HI-6135 device provides a complete Remote Terminal interface between a host processor and MIL-STD-1553B bus. The terminal communicates with the MIL-STD-1553 buses through an on-chip dual bus transceiver and external transformers. The user allocates 16K bytes (8K x 17-bit words) of on-chip static RAM to suit application requirements.

The HI-6135 communicates with the host via a 40 MHz 4-wire serial peripheral interface (SPI). Programmable interrupts provide terminal status to the host processor. Circular data buffers in RAM have interrupts for rollover and programmable “level attained”.

The HI-6135 can be configured for automatic self-initialization after reset. A dedicated SPI port reads data from an external serial EEPROM to fully configure registers and RAM and optionally start execution.

Software

Various software support options are available for the HI-6135. A development kit (ADK-6135) includes low level software that demonstrates the broad features of the device. The MAMBA^TM Family API Application Development Kit (ADK-6138API) includes Holt's MIL-STD-1553 Application Programming Interface (API) library. In addition, Linux and Bare Metal (ARM) Software Drivers are available. Details are outlined below.
