Holt Integrated Circuits announced a low profile MIL-STD-1553 fully integrated terminal solution. The device, HI-2130, contains MIL-STD-1553 protocol logic, dual transceivers and dual transformers in a low profile compact package.
The HI-2130 die is hermetically sealed on a ceramic BGA substrate and dual transformers are mounted in the same package. The ceramic substrate allows extended temperature operation from −55oC to +125oC, exceeding operating temperatures of competing integrated devices. The device operates over the full temperature range with no heat sink and no duty cycle or bus load constraints.
The HI-2130 combines the functionality of Holt’s HI-6130 and HI-6131, giving the user a choice of 16-bit parallel bus or SPI host interface in a single package. In addition, the new HI-2130 provides the added benefit of integrated transformers in a lower profile and smaller footprint than the original HI-6130 solution, offering customers a compact low cost solution.
Each device contains a Bus Controller (BC), a Bus Monitor Terminal (MT) and two independent Remote Terminals (RTs). Any combination of the contained MIL‑STD-1553 functions can be enabled for concurrent operation. The enabled terminals communicate with the MIL-STD-1553 buses through integral dual bus transceivers and transformers. The user allocates 64K bytes of on-chip static RAM between terminals to suit application requirements. The 32K x 16-bit RAM has an error detection and correction option which provides additional robustness in high altitude or other applications subject to SEU events. The HI-2130 can also be configured for automatic self-initialization via a dedicated SPI port from an external serial EEPROM memory.
