HI-6138
DESCRIPTION
The 3.3V CMOS HI-6138 device is a member of Holt’s MIL-STD-1553 MAMBATM family and provides a plete 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 bination of the contained 1553 functions can be enabed for concurrent operation. The enabled terminals municate 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 municates 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”.
