HI-6139
World's smallest solution. 3.3V. MIL-STD-1553A/B. BC, MT and RT may operate concurrently. Integrated dual transceivers. 8K x 17 RAM with parity, 40 MHz Serial Peripheral host Interface (SPI).
The 3.3V CMOS HI-6139 device is a member of Holt’s MIL-STD-1553 MAMBATM family and provides a complete single or multi-function interface between a host processor and MIL-STD-1553B bus (a register bit provides optional MIL-STD-1553A operation). Each IC contains a Bus Controller (BC), a Bus Monitor Terminal (MT) and a Remote Terminal (RT). Any combination of the contained 1553 functions can be enabed for concurrent operation. The enabled terminals communicate with the MIL-STD-1553 buses through a shared on-chip dual bus transceiver and external transformers. The user allocates 16K bytes of on-chip static RAM between devices to suit application requirements.
The HI-6139 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-6139 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 for any subset of one to three-terminal devices.
Software
Various software support options are available for the HI-6139. A development kit (ADK-6139) includes low level software that demonstrates the broad features of the device. In addition, Linux and Bare Metal (ARM) Software Drivers are available.
