MIL-STD-1553 Protocol IP Core

Holt's MIL-STD-1553/1760 IP solutions are the world’s first MIL-STD-1553 Design Assurance Level A (DAL A) DO-254 certifiable IP Cores. These IP cores are based on Holt’s HI-6130/31 and MAMBA™ families, providing a complete single or multi-function protocol interface between a host processor and MIL-STD-1553B bus. Various combinations of BC, RT or MT functions with high-performance synchronous host interfaces are offered. The host interface provides easy connection to AMBA AXI4 interface protocol or PCI-Express and enables terminals to communicate with the MIL-STD-1553 buses through a shared dual bus transceiver, HI-1587, and external transformer, also available from Holt. The HI-1587, featuring 1.8V, 2.5V and 3.3V compatible digital I/O, includes an integrated IP security module necessary to enable the IP, eliminating the need for a traditional external IP dongle chip, commonly used with other IP solutions. 

All RT devices are MIL-STD-1760 compliant, responding to valid messages with status word Busy Bit set within 150ms following power-on. 

The Holt IP Core product includes the HI-6300 IP Core, a Verilog test bench, and supporting documentation, allowing designers to instantiate the core in a variety of FPGA implementations.
