The HI-6300 is a MIL-STD-1553 / MIL-STD-1760 IP core for military and commercial applications. The core is based on Holt’s independently-validated monolithic protocol ICs for MIL-STD-1553, namely Holt’s HI-6130 and MAMBATM families, and is fully software compatible with them.  


The HI-6300-xxx-B core offers an independently validated Remote Terminal (RT) and Monitor Terminal (MT) with a synchronous host interface. The terminal communicates with the MIL-STD-1553 buses through a shared dual bus transceiver, HI-1587, and external transformer, also available from Holt. The HI-1587 transceiver features an integrated IP security module necessary to enable the IP. This eliminates the need for a traditional external IP dongle chip, commonly used with other IP solutions. The HI-1587 is also the first MIL-STD-1553 transceiver to have 1.8V, 2.5V and 3.3V compatible digital I/O, making it easier to interface with a broad range of FPGAs.


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.
