Holt Integrated Circuits, a world leader in data bus ICs for the avionics and military markets, proudly announces their next-generation MIL-STD-1553 bus terminal products, the HI-6130  and HI-6131 . Each product is a single chip integration of all the logic, memory, and analog interface necessary to make the world’s smallest, complete 3.3V BC/MT/RT and, additionally, the first multi-terminal operation possible in a single IC. The results are lower-cost, proven Holt reliability, and availability from stock, making the HI-6130 and HI-6131 an excellent choice for redesigns as well as new designs. Both devices are available in very compact surface-mount plastic packages and, with Holt’s proven history for longevity across its entire product line, the HI?6130 and HI?6131 will be available well into the future to meet this essential requirement of the avionics and military industry. Furthermore, all Holt MIL-STD-1553 devices are DO-254 certifiable, with support documentation available to customers upon request.
Key features include concurrent operation for up to four terminals (Bus Controller, Monitor Terminal and one or two Remote Terminals), 64K bytes of internal static RAM with optional error detection/correction, a fully programmable Bus Controller with a 28 op-code instruction set, simple and IRIG-106 compatible monitor modes, two independent full-function Remote Terminals, an independent time counter and clock source for each terminal, programmable interrupts, and a built-in self-test of protocol logic, digital signal paths and internal RAM.
“Holt constantly strives to provide new, innovative and reliable MIL-STD-1553 solutions that meet customer needs which are also less expensive and more readily available alternatives to the existing multi-chip module solutions on the market today,” said David Mead, Executive Vice President and COO at Holt. “The new devices fill out Holt’s complete range of lower cost, short lead-time MIL-STD-1553 products for this important market.”
The HI-6130 and HI-6131 can be configured for automatic self-initialization, further minimizing external host interaction. A dedicated SPI port reads data from an external serial EEPROM memory to fully configure the internal RAM, registers and host interrupts.
The HI-6130 uses a 16-bit parallel host bus interface in a 100-pin PQFP package. The HI-6131 uses a 4-wire Serial Peripheral host Interface (SPI) and comes in a 64-pin PQFP and 64-pin QFN. At only 9mm x 9mm x 1mm, the 64-pin QFN is the world’s smallest multi-terminal solution. Both devices handle all aspects of the MIL-STD-1553 protocol, including message encoding, decoding, error detection, illegal command detection and data buffering. Host data management is simplified by storing message information and data in the on-chip 32K x 16-bit static RAM.
The devices are offered in industrial -40oC to + 85oC, or extended, -55oC to + 125oC temperature ranges as well as extended temperature range with optional burn-in. All package configurations and temperature ranges are also available in a “RoHS compliant” lead-free option. Datasheet, samples and evaluation kits for both devices, along with supporting software, are currently available on request.
