HI-6138

November, 2016 MAMBATM: HI-6138 3.3V BC / MT / RT MIL-STD-1553 / MIL-STD-1760 Compact Multi-Terminal Device with SPI Host Interface GENERAL DESCRIPTION The 3.3V CMOS HI-6138 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. 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-6138 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 programmab...
