HI-6131PQIF

HI-6131PQIF is an integrated circuit product launched by Holt Corporation, specifically designed for the MIL-STD-1553B protocol. This chip provides a complete single or multi-functional interface, connecting the main processor and MIL-STD-1553B bus. HI-6131PQIF has the following features and functions:

Host interface options: HI-6131PQIF communicates with the host through a 4-wire serial peripheral interface (SPI), which helps reduce footprint and complexity of interconnect wiring. ‌

Internal resources: Each HI-6131PQIF integrated circuit includes a shared on-chip dual bus transceiver and external transformer, which communicates with the MIL-STD-1553 bus. In addition, the device also provides 64K bytes of on-chip static RAM to meet various application requirements. ‌

Programmable: HI-6131PQIF supports multiple programming options, including programmable interrupts that provide terminal status to the host processor, and circular data stacks in RAM with flip and programmable "reach level" interrupts. ‌

Autonomous operation: The chip can be configured to automatically initialize itself after reset, reducing the need for host intervention and achieving autonomous terminal operation. ‌
