HI-6131

October, 2016 HI-6130 / HI-6131 / HI-6132 MIL-STD-1553 / MIL-STD-1760 3.3V BC / MT / RT Multi-Terminal Device GENERAL DESCRIPTION The 3.3V CMOS HI-613x device 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 two independent Remote Terminals (RTs). Any combination of the contained 1553 functions can be enabled for concurrent operation. The enabled terminals communicate with the MIL-STD-1553 buses through a shared on-chip dual bus transceiver and external transformer. The user allocates 64K bytes of on-chip static RAM between devices to suit application requirements. Two options are offered for host access to internal registers and static RAM: The HI-6130 uses a 16-bit parallel bus; the HI-6131 communicates with the host via a 4-wire serial peripheral interface (SPI). The HI6132 combines both 16-bit parallel bus and SPI in a single 15 x 15mm hermetically seal...
