HI-6135

November, 2016 MAMBATM: HI-6135 3.3V MIL-STD-1553 / MIL-STD-1760 Compact Remote Terminal with SPI Host Interface GENERAL DESCRIPTION PIN CONFIGURATION (TOP) The 3.3V CMOS HI-6135 device is a member of Holt’s MIL-STD-1553 MAMBATM family and 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 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 selfinitialization after reset. A dedicated SPI port reads data from an external serial EEPROM to fully configure registers and RAM and optionally s...
